Question

Hello, FYI

  I try to start firefox (22) in safe mode and the freezing problem is still here.
  The browser freeze when after call to multipart/data form. It seems to be released after a timeout (aprox 30s -1 min).

With aurora 21.0.a2 the problem does not occur, as for other browsers.

Seems like this bug (still unsolved): https://bugzilla.mozilla.org/show_bug.cgi?id=859038 If you have the same problem, consider voting up that bug.

Edit
Comment by a forum moderator. I have put a line through some of the above. That bug and some related bugs are resolved i.e.the known issues seem to have been fixed. There is now no point in voting in those bugs. ~J99

Hello,

Try disabling graphics hardware acceleration. Since this feature was added to Firefox, it has gradually improved, but there still are a few glitches.

You might need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.).

Then perform these steps:

• Click the orange Firefox button at the top left, then select the "Options" button, or, if there is no Firefox button at the top, go to Tools > Options.
• In the Firefox options window click the Advanced tab, then select "General".
• In the settings list, you should find the Use hardware acceleration when available checkbox. Uncheck this checkbox.
• Now, restart Firefox and see if the problems persist.

Additionally, please check for updates for your graphics driver by following the steps mentioned in the following Knowledge base articles:

• Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems

• Upgrade your graphics drivers to use hardware acceleration and WebGL

Did this fix your problems? Please report back to us!

Thank you.

Ok, I followed your instructions and it made no difference. Thank you for the suggestion. Judging from the comments on the Bugzilla board, this is a very specific bug that is reproducible by many users. It may require a code change and update rather than fiddling on the users' end. Or perhaps there is a bug in the most recent Java version? Firefox runs on Java, yes?

Hi NerdyTechie, I think there might be two different problems being discussed in this thread:

(1) Original issue that Firefox freezes Windows after starting the browser;

(2) Second issue that when you resume Windows from "sleep", that Firefox 21 is unresponsive for a long period of time (but other applications are not affected).

Which problem do you have?

For what it's worth, Firefox does not run on Java and you do not need the Java plugin for most sites.

Hi Aethyr, could you also undertake these prophylactic steps that address the most common issues with the Flash player plugin. I'm sure you've seen some of it before, but just in case:

(1) Make sure all recorders/downloaders that interact with Flash media are as up-to-date as possible, or disable them.

(2) Disable hardware graphics acceleration in Firefox and in Flash

(A) In Firefox, [as noted in a previous post] un-check the box here and restart:

orange Firefox button (or Tools menu) > Options > Advanced > General > "Use hardware acceleration when available"

(B) In Flash, see this support article from Adobe: http://helpx.adobe.com/flash-player/kb/video-playback-issues.html#main_Solve_video_playback_issues

(3) Disable protected mode (Windows Vista/7/8)

See this support article from Adobe under the heading "Last Resort": Adobe Forums: How do I troubleshoot Flash Player's protected mode for Firefox?

Thanks for the prompt reply. I should have included the bug report I was talking about. It's this one: https://bugzilla.mozilla.org/show_bug.cgi?id=859038 If the computer falls asleep with Firefox open, then upon awakening, has a problem refreshing the UI. Clicking the systray a couple of times forces a single refresh but the problem continues. I can quit Firefox normally, choose close all tabs, and when I reopen Firefox I can choose to restore the prior session and everything works fine. This is definitely related to something that is happening when the computer either falls asleep or wakes from sleep.

NerdyTechie,

Your problem is off topic for this thread. Please start a new thread or join a discussion about Firefox being unresponsive after resuming from "sleep".

Disabling graphics hardware acceleration; Seems to be the solution to my problem, Thanks.

OOps - my bad. I read so many threads that I thought this was another one of them. I'll stick to bugzilla thread then. Thanks for the heads-up.

To the original poster with the problem, i had the same issue just tonight 7/9 and fixed it.

The problem was my computer asked me to update my Adobe Flash Player. I did so but it didn't install saying 'action list not found'. I am on Windows 7 btw. Then when I tried to run FF 22, it would just hang and I would need to kill my computer and turn it back on. I tried my other browsers such as Chrome and IE and same thing, when it tried to load a page, whole computer froze and i had to turn off turn on the computer to get it back up.

I uninstalled FF and then used IE to download Flash Player. I got the same error with the 'action list not found' but directed me to a troubleshooting page. I did a search on 'actionlist not found' error, and it had a direct download link to flash thru IE. I did that, installed the newest version of Flash and it didnt give me the actionlist error.

Then I used Chrome, opened the browser, went to a page, then it froze on me again, but this time I let it run, and some window popped up for split second so I didnt know what it said, but then the webpage unfroze and everything was back to normal. I then redownloaded FF and it has been working without the freezing problem ever since.

I hope this helps.

jfkobama,
Not too sure your solution is likely to work for everyone.

It may be noted that FlashPlayer is separate on Firefox IE & Chrome. It is totally different software on IE Firefox & Chrome. I am not sure however if some of the installers may be able to update Firefox & IE at the same time. The Flash Player for Chrome is integrated with Chrome and will update separately.

(As an aside IIRC it may actually be possible to run the Chrome plugin in Firefox under linux, but it that is obviously not supported and is not something I have ever tried)

I've had this problem too, have been keeping flash and flash player up to date. I've disabled the 'use hardware acceleration where possible' option and will notify if this seems to fix the problem. Using Firefox 22.0 Windows 7 Professional (64bit)

Recently I had been having this problem also. I tried disabling all add-ons and still I had this issue. Finally I disabled the "Java Deployment Toolkit" plugin and that appears to have solved my problem. Previously I wasn't able to go 20 minutes before a lockup and now I haven't had one in several hours.

As an added bonus that plugin is no to be vulnerable so I also increased the security of my system!

I am running Windows 7 and have experienced Firefox 22 hanging after wakeup as well. I found that if I click a tab on the hung page I get no response other than the titlebar changes to the title of the page associated with that tab. But if I click a menu item like TOOLS after I click the tab the page refreshes with the page of the last tab I clicked. None of the links work on the page. The menu items drop down, the submenus are active but clicking on one does nothing

Hi page1, the problem of Firefox taking an excessively long time to wake up from sleep should be fixed in Firefox 23 (coming August 6th). If you want to try Firefox 23 now, you can install it from the beta page here:

http://www.mozilla.org/firefox/beta/

Before doing that, you might want to make a backup of your personal settings folder (AKA your Firefox profile folder) just in case something goes wrong. This article has some tips on that: Back up and restore information in Firefox profiles.

Recent Firefox freeze my computer's manage (windows explorer) frequently. When it happens, the taskbar locked with busy cursor, you can not access it anymore, start button, running tasks etc all locked. I can bring up the task process explorer (a better version of task manager) by press CTRL+ALT+DEL and can kill all the live processes except firefox. When it locked the windows Explorer, FireFox can not be killed. I even can not kill the Explorer.

Some time the explorer is not frozen, but the problem came from logout, whenever I try to shutdown the machine, it hangs on there forever, and again it is firefox locked on background and obviously windows can not shut it down.

The aggressive updates/upgradings of FF are not good. It simple broken what was working and introduced more problems. I do not think aggressive upgrading will bring more users, actually it is killing Firefox cause upgrading causes more problems than the features added in.

FF has plenty of features already, and most of user even do not uses half of them. So why FF is trying to add more features by broken it? Stability is much more important.

Hi wgm192, does this problem occur when you interact with Windows to upload, save, or download files? I don't want to torment you with having to restart over and over, but if you can find a pattern to what Firefox is doing when it locks up, that would be helpful in tracking down the cause of it.

Meanwhile, it might be helpful to run Firefox in its Safe Mode. The disadvantage is that your extensions are disabled. More info: Troubleshoot Firefox issues using Safe Mode.

You can restart Firefox in Safe Mode using

Help > Restart with Add-ons Disabled

In the dialog, click "Start in Safe Mode" (not Reset)

Or, if Firefox not running, hold down the Shift key when starting it to call up the Safe Mode dialog.

Hi jscher2000,

Recently, I did download and upload files quite often.

But I noticed the previous version had problem of hang up on FlashPlayer, it looks different from current case, it locked up whole screen with CPU usage running high for about 5 seconds (or longer), then pop up a prompt windows saying that the flashplayer plug-in crashed. When that happened, Windows also could not be log off and be shutdown, and the FireFox process also could not be killed even windows comes back to 'alive' .

After upgraded to latest version, it doesn't lock whole screen anymore , nor will it show the flashplayer crashing window. When Firefox had problem and stuck in background running, I even do not notice that, because all running program still running well except the explorer task bar area, When I move mouse to task-bar and see the busy running cursor , then I know something happened..

If I noticed something new, I'll send it to you.

Thanks.

OS : Vista FF version: 23.0.1 CPU : core 2 duo. ..

Just subscribed cause, as i had the last version of firefox, (23), i have this problem too, firefox, randomly freeze my whole computer, to only solve the problem via hard reset button, when it freeze my PC, nothing else can be done, this began to occur, since 21 version, and neither safe mode, or disabling the extensions help, so i decided to uninstall firefox completely, even as i have now, a new fresh windows 7 install since yesterday, when i install firefox, the problem comes back (so, no chance for a virus, defective driver or whatever to justify this behavior), then i decided to get rid of firefox and go for chrome.........but as i couldn't get along with google (no youtube download extension, that sucks).......i decided to take the most unexpected choice, since there is no workaround for this problem in firefox............i have installed nightly 64 bit version, in hope to solution this, as i love firefox and it's extensions........hope these freeze keeps away for a while, and please........resolve this serious issue, i don't want to abandon my favorite browser for this problem.

PD: As for not making another post, i have to report that actually Nightly 64 Bit, didn't crash the way firefox done, when it crash it only stops responding as the program itself, so, no computer crash or freeze as nightly is being used, so, for a temporary solution for 64 bit OS users, this is quite a good one for me.....i bet nightly 32 bit, works the same way too.

PD2: Today Nightly updated itself to this version, 26.0a1 (2013-09-17), and i experienced my first crash, so, what is hapening, my PC will damage with so mane hard resets.

Hi Everyone,

This thread at present has over 200 metoo votes and nearly 7.5k views. So no one is saying there is not a real problem needing addressing.

I will try to go through the thread in a short while and see if I can provide links XXXX to what seems to have been the most helpful points, it may save you a little effort.

Of course Firefox should not freeze or leak memory and of course Mozilla Firefox cares about such problems, although you may not notice that talking amongst others with a similar problem.

I am sure we have solved this issue for some of you. I hope anyone posting or considering posting in this thread is able to take the time to read this explanation.

Sorry if this is rather a long post and not offering each of you a direct solution but I feel it may help you all to understand some background information and the importance of having your own threads (Which you may of course crosslink here so everyone is able to follow them and see the larger issue).

Purpose of the Forum
I know this is frustrating but we are mainly fellow users trying to help one another. We try to find solutions but it is not the place to discuss development decisions or ask for enhancements to Firefox. It is not even the place to file bug reports to fix problems. You are unlikely to get developer attention here.

Bug Reports and Bug Fixes
So I have just said you will not get developer attention here and it is not the place to file bug reports. What should you do ?
Well if you are lucky enough to be a developer or coder with time to spare fire file a bug and better still dive in and fix some of the bugs yourself. The bug reporting site is a work space for developers. Very occasionally they request our (user) assistance for instance in demonstrating or identifying steps to reproduce a bug, but normally the best thing we can do is to file good bugs and let them get on with the work.
I did not answer what it is you should do, and the answer to that is in the first instance ask a question here on the forum ! If necessary we should be able to help you file a bug where that is appropriate, as long as you have the time to help us do that. You should also use the input feedback and turn on telemetry. (See under). Remember

1. If it is a valid bug is filed and gets fixed it helps all of those with that particular problem not just you. Many bug fixes will help hundreds or thousands of others.
2. But a badly written bug could be ignored and considered incomplete. That wastes triargers &/or developers time and benefits no one.

• Bug writing guidelines for anyone interested by the way are here
  https://developer.mozilla.org/en-US/docs/Mozilla/QA/Bug_writing_guidelines

Complain using feedback & turn on Telemetry
Some of you viewing this thread will not find it helpful, and will not find a solution to your problem. Make that known by making a short comment from a supported version of Firefox on the two subjects forum helpfulness and memory or freeze problems with Firefox

• use https://input.mozilla.org/en-US/feedback

Attempts are made to analyse the comments by subject and number to see what may need attention.

• • comments are public and can be seen here XXXX
• turn on telemetry, it was brought out after a bad memory regression in Firefox 4 was initially missed by developers. Using Telemetry should help developers detect real life issues with memory and freezes
  • Share telemetry data with Mozilla to help improve Firefox
  • public data may be seen here XXXX

Crash Reports, Hangs & Freezes
This is the basic general information

• Crashes
  If you have a Firefox crash you should submit a crash report. That will help Mozilla Firefox. but you also need to look at a kb articles &/or ask a question about the crash. Submitting crash reports does not directly fix your problem or get you a solution.
  • see Firefox crashes - Troubleshoot, prevent and get help fixing crashes
• Hangs
  see Firefox hangs or is not responding - How to fix
  • Note many freezes or hangs may relate to Video &/or Flash use
    Adobe Flash plugin has crashed - Prevent it from happening again
    Send plugin crash reports to help Mozilla improve Firefox

Memory Problems
Developers know of some issues, and have had a project to fix a lot of memory issues. You need to remember that often problems will in fact relate to third party software or problem websites.

What is Mozzila Firefox doing then
Generaly

• Memory reporting tools have been improved and there is an on going project to fix problems & improve tools.
• Work is continuing on Firefox Health Report. We are aware the Crash reporting situation should be improved.
• I understand
  • Consideration is being given to improve the emails (presently rather unhelpful IMHO) that are sent out sometimes after a crash report is submitted.
  • There is a new reporter relating to Flash Player that is being trialled at present.

And if YOU start your own thread and ask a question quick direct link) someone will do their best to help you with YOUR Firefox problem.

Minority Edge Case

1. Firstly why should we consider something is a minority problem ?
   • Because we have results from the crash reports, telemetry, input feedback and questions on this forum
2. So why am I finding loads of posts and questions about my problem if it does not affect everyone ?
   • Remember the userbase size.

With a user base approaching 1/2 billion someone will have almost any problem you wish to name. Even something affecting a fraction of a single percentage point affect thousands or even millions of users. Firefox is highly customisable and used on differing platforms and accesses sites all over the internet. We really do need a lot of detail to track down the problems affecting minority groups.

Saying me too and please fix it draws attention to a problem but does not help in narrowing down where that problem lies so that it may be addressed and fixed. If it is an issue affecting minority it is critical to identify the important factors.

Usless answers | scripts |templates |boilerplate |Articles
Yes a lot of what you see or read will not directly apply to you or help in your specific circumstances and looks impersonal. Yes I have to agree with that, but you need to bear in mind the following

• It is not just you reading the information
  • Threads may be read by many people. Some including this one are looked at by thousands.
  • The Knowledge Base articles are read by many more people. Top articles are read by tens or hundreds of thousands of people per week, and we strive to constantly review articles to maintain and maximise the helpfulness.

It is a pain in the Proverbial starting a new thread
Yes I tend to agree that we should be able to handle this better. All I can do is offer you a more direct and quicker shortcut to use

It does make it immensely easier to help you if

1. You have your own thread
2. And carefully follow the prompts to add the full troubleshooting information.
3. Then do your best to supply any additional information requested.

I will fill in some of the blanks xxx in this later today

Sorry John99, but for everything you say, this problem is still annoying and can harm a computer seriously, and as for firefox 24, the problem persist in a minor basis, but still freeze completely a pc, in nightly, it began to hapened since a couple of updates since last week, and if this get to have no solution, guess we gotta replace firefox for another browser, cause, we don't want to make our hard disks useless.

Created an account just to post here that disabling "use hardware acceleration" in advanced settings fixed the problem for me. A suggestion to Firefox crew - this setting should be removed or at least be included with a warning that it can make a system unstable. I had to check many things including updating BIOS, testing hard drives etc. - my PC just kept freezing. This was the worst in 3 years since I have this computer. Hard to believe that one setting in Firefox was causing all this!

i have the same problem from 2-3 days. my pc just start up normally, when i opened firefox to browse then suddenly the screen was freezed (or maybe the win7 was). i got to hard reset my pc to reboot. after a couple of the same thing happened, i realized that it wasn't entirely firefox mistakes. the main culprit was the addon adobe flash that acting automatically crazy like it meant to destroy any pc who dare coming to his website :)

anyway, it's strange when i use chrome there's nothing like this happened, only in firefox. u gotta respond quick, mozilla or the unhappy users will quickly turn the likes to the others :)

Hello! I've been having the same problem for months now. Stumbled across this thread and thought I'd try the Safe Mode option as described, but sadly, this causes Firefox to crash upon starting. Firefox is by far my favourite browser so please help fix this problem!? I can only agree with all other posts here as to how I've tried fixing (without addons, updating flash etc) My PC is also set to go to sleep often so maybe the problem is related to that?

Hi Elfiemyrtle, if your Firefox is crashing instead of freezing (and having to be killed), you may have some additional data you can provide to better identify the issue. Could you start a new question including your system information and the crash IDs described in the last section of the crashes article:

• Firefox crashes - Troubleshoot, prevent and get help fixing crashes
• New question form: https://support.mozilla.org/en-US/questions/new/desktop/fix-problems (scroll down past the suggestions to continue with the 3-page form)

"Sleep" on Windows has been a problem in a few recent versions, but the bug is thought to have been fixed by now.

Here to report progres, as far a things goes, azovsky's solution proves right with the issue, looks like flash and hardware acceleration, are part of this problem, i dissabled hardware acceleration and for now, the problem has gone............thanks azovsky, ando hope things keep this way.....for now

I have experienced something similar to the original poster. My problems began approximatley July 21st, 2013. I also experience cursor lag and subsequent system lockup when using Firefox, although sometimes it recovers after this lag, as the OP stated. However, the lockup rarely occurs for me soon after starting Firefox. Additionally, I frequently experience system lockups when the operating system transitions my monitors to standby mode. Less frequently, I also experience system lockups when the computer enters or resumes from sleep, enters hibernate, or shuts down.

I have traced this problem to my graphics card, which is the same as the OP, an EVGA GTX 460 (although mine is the 1GB version). I swapped my graphics card with my girlfriend's EVGA GTX 275. Now my computer is stable when using Firefox or changing power modes, and her computer experiences the instability.

The cause of my problem may be unrelated to the OP's problem, but I found it interesting that he has the same graphics card and that his description of the problem is very similar to what I experience when my system locks up while using Firefox. I'm now curious if all my crashes are due to an interaction between my GTX 460 and Firefox, rather than simply a hardware failure on my GTX 460. I'm going to test if I experience lockups without running Firefox at all during my sessions.

Ever since version 3.5, Firefox has frozen on my Mac. Firefox starts up well, but as soon as I go to a website it freezes. I have tried several of the new versions including the latest one (25), after trashing previous versions. I have tried every "fix" suggested in these forums, including starting up in safe mode. It hasn't helped. And I don't see why all these workarounds should be necessary. I also use three other browsers that work with no problem and have done so as soon as I've opened and launched them.

Just out of curiosity xkreiss, have you tried resetting your Prebindings or dyld shared cache? This usually helps clear slowdowns and other problems with newly installed applications. Running the following command in the Terminal should ensure the dyld cache is set up properly:

update_dyld_shared_cache -root / -force

You can use this option to update the caches used by dyld and sometimes correct problems. It replaces the update_prebinding command used in the previous versions of Mac OS X, but is now obsolete in Mac OS X 10.6 and higher.

Hi Saneman

Thanks for the suggestion. I'll try it.

First off, my issue is the same as the OP. Firefox seems to be causing my computer to freeze, ie. is not responsive to tapping the <shift-lock> key, mouse movement, control-alt-delete, prayer or cussing up a storm. The only resolution is a reset or power off and on. I can also note that there is no hard drive activity during one of these freezes. No other browser has caused this. I have tried Firefox portable from portableapps.com as well and the same issue occurred.

I think it started around the same time that NickdeClaw says it started for him, July 21st, 2013. After reading through this topic I decided to start with one thing at a time to try to track this down. First off I have disabled all but the "necessary" add-ons, ie. LastPass and Tree Style Tabs. Note these are the Add-ons not the Plug-ins. I still have Shockwave Flash enabled as well as several Google Plug-ins, Silverlight and a couple MS Office plug-ins that I wasn't aware had been placed there. :) I have disabled hardware acceleration in Firefox as my first foray into tracking down this nasty bug. I'll let you know if that squashed the bug after waiting a few days to make sure. One last thing, I don't think I was accessing any video intensive pages during some of these crashes. I can't be sure but looking at my current tabs now there aren't any "video" tabs open and I had a crash earlier with the same tabs and that finally prompted me to go looking for a fix and thus finding this thread.

I've been having this same issue in FF 25.01

I have narrowed it down to the windows user account which is set as admin.

I have tried all of the options found here without success.

After switching to the real admin account I have not had any issues.

Personally, I think the ISP's (AT&T in my case) are monkeying around in the background.

Other issues I am having is not being able to access my own website at www.electricalmanagementsoltuions.com from different servers but the same ISP (AT&T) even though my host tells me the site is up & running.

This is still a work in progress.

Complete BS!

Hi EVERYONE (IF YOU POST HERE IT WILL PROBABLY BE IGNORED !!! )

Sorry if this is inconvenient and not what you wish to hear but may I remind you all that

• Developers do not look at this forum.
• There are other methods to comment / complain.
• If you have a problem and would like us to help you
  • Post your own question, in your own thread and follow the prompts to provide troubleshooting information.
    PLEASE Use this special link
  • Please look at my log explanatory post /questions/963963?page=2#answer-479420 above for more information on
    - the reasoning behind this comment,
    - some potential or known solutions.
    

I posted here that I was having the same problem as the OP, ie. my computer running Windows 7 Ultimate would freeze and it appeared that it only happened when Firefox was running. I read some of the possible solutions and decided to try the easiest which was disabling hardware video acceleration. I said I'd report back on the result. It was on November 19 2013 that I disabled hardware video acceleration. I leave my computer on all the time and have Firefox running. It is now December 02 2013 and so far I have not had any freezes. Thanks for the help. Hopefully the problem is solved.

FlippityWidget,
Glad for you. Great that it has worked ok now for the last month after disabling hardware acceleration.

Thanks for adding that comment about disabling hardware acceleration solving the problem. We often suggest as as an initial test using Firefox's safe mode.

This allows us to home in on this sort of problem and other potential causes because one of the changes in Firefox's safe mode is disabling hardware acceleration.

You may wish to try updating your graphics drivers (or conversely backing out the last update as a test) because that may improve matters and sometimes may allow hardware acceleration to work properly and speed up rather than slow things down.

• Please see Upgrade your graphics drivers to use hardware acceleration and WebGL
  (Note to others -It also mentions how to disable hardware acceleration)

Anyone else thinking of posting may benefit from glancing at my post just above /questions/963963?page=2#answer-507483.

Thanks John99 for the response and the helpful info on additional things to try.

I'll explain what I tried to resolve my problem prior to consulting these forums. Maybe it will benefit others to go through the process. The very first thing I tried was to uninstall Firefox and reinstall it. Then after reinstalling I imported my old profile. I gave it a few days and my system hung. I do run a few add-ons. I won't list them here but I think I usually have about 10-12 various add-ons. I've been running the same ones for a few years with no issues but I am aware that can change with every Firefox update. So the next step was to disable all of them except a couple essential ones, LastPass being one and I can't remeber the other one right now. AGain my system hung. So I tried a different route and loaded up the Portable Apps version of Firefox and ran it without any add-ons. My system hung again. It was at that time I decided to use the tremendous resource I have at my fingertips known as the Interweb and the Google. : ) That's when I came across this thread.

As far as my video driver is concerned I recently (within the last week or so) updated my video drivers. I was trying to solve a different problem and whilst doing that I updated a few other drivers as well. I am running an Nvidia GT 550Ti video card. I don't know if the hardware video acceleration issue is linked a particular video card or not. I should add that I do keep my system and drivers up to date as a general rule. So I am fairly certain that my video driver was updated regularly anyway because the NVidia "GForce Experience" application that runs in the background notifies me of updates.

So I have a question for you. Well, maybe more than one question. Does the Firefox error reporting capability survive a system hang? I mean can Firefox, when the system has been rebooted after hanging-up, gather information to report back to Mozilla about the problem? I can tell you that when my system stopped responding I saw no hard drive activity. The [shift-lock] key did not get a response from the system. Pressing [ctrl]-[shift]-[esc] did not bring up the task manager and [ctrl]-[alt]-[del] did not get a response from the system. I let the computer sit for some time just to see if the OS had become busy but it never recovered until I did a hard reset. Based on that condition I wasn't sure if Firefox ever had a chance to gather information for a crash report to Mozilla.

Other than enabling the three checkboxes under the "Data Choices" tab in the Tools-->Options box is there anything else I can do that will help to provide Mozilla with information to debug issues with Firefox?

Thanks again for the help.

This reply about locking up from sleep is not off topic. It is completely related I have the same problem with the error message popping up saying Shockwave has stopped working, continue or stop.

Hi reallymurphy, when scripts hang on a page that uses Flash, this may be caused by the protected mode feature of the Flash Player plugin. See my experience with this problem here: Flash hangs Firefox (eventually get script continue/stop dialog).
