Script quits working - this is when multiple tabs are open and I go to close one. First, I have to click to close the tab multiple times before it closes, then a 'new tab' opens on it's own. The script error reads Script: chrome://browser/content/tabbrowser.xml:1644 I have to then close the window, reopen it, and then all previous tabs open, and yet another 'new tab' opens. None of my tabs are closing with one click, all need two or more before they close. I love Firefox and have used for years, this really must be fixed.

I just updated to 4.o RC1. I'm running Windows 7 Ultimate OS. Every time I open multiple tabs, FF crashes. Very frustrating. Any ideas? If not, is there a way to roll back to Beta release 12? This never happened with that version.

In what seems like a relentless update/upgrade competition with the "other" browsers, Firefox 11 is NOW not playing nice with Shockwave Flash, or is it vice-versa. This didn't start happening until I "upgraded" to Firefox 11.0

YES, I've updated ALL the plugins (Who invented this plug-in hassle, anyway?), as is ABSOLUTELY required whenever Firefox goes through one of its myriad of updates/upgrades. I've uninstalled/reinstalled Flash, and my WinXP Pro is up-to-date. I haven't experienced this torrential headache with IE 8.0, OR before F-11.

Is there a Firefox 11.0.0.1.2.3.4 patch in-the-works, or do I have to consider one of the "others"? HELP ME!

I've recently been lucky to get my hands on Windows 8 from my college (full Windows 8 Professional, not the 90 day trail.) and installed Firefox. Boy was it a mess, I know Windows 8 has yet to be released officially to the public but Firefox will crash and hang and just be all around terrible to use. I've tried Google Chrome and have had none of these problems with it, same as IE (I know IE sucks but just adding it to my trail list). I know flash is integrated into both of those browsers but could that be the problem that Firefox is having when it comes to Windows 8? Anyways my main reason for posting this is to let those who work with Firefox that there is a compatibility problem with it right now.

Firefox 10 and 11beta are crashing instantly while trying to load a majority of sites such as newspapers, youtube.com etc. I could not track it down to a particular pattern, but the presence of videos on the sites was a facilitating factor. It even crashed on the Mozilla Extensions website. I tried all the described steps, starting in safe mode, disabling all plugins and all extensions but it did not work. I re-installed Firefox 9.0.1 and it works. No crash reports were generated. I do not have any of the applications mentioned to interfere with Firefox either. I have a solution for now after the downgrade, so it's not urgent for me - but would like to let you know that this is a real issue.

Firefox crashes CONSTANTLY. It is non-discriminatory as to when, where, what or why I'm doing anything. No one web page has done it. I have always submitted results and asked to be notified and have heard bupkiss... I would attache my last crash data, except you guys have 30 crash dumps already. I've tried disabling all addons (Ghostery, ABP and Flash) to no avail. I'm currently running unsynced from my other devices to see if that makes a difference.

I switched because I was tired of IEs pop up and crap, but now I think IE is a Godsend. If you guys can't get this fixed, I'll move on to Chrome!

The damn thing JUST crashed AGAIN trying to Copy and Paste the Help>Troubleshooting info... I'm done.

I just updated to firefox 3.6.8 this morning after getting prompted to update as I started firefox. The firefox update successfully installed page said that I should update to the latest adobe flashplayer, so I did that as well, although that installation failed for whatever reason. I figured that I would update it later. I started watching live streaming videos on a website, and it was working for awhile, but firefox started to not respond. I tried opening up task manager, but even that started to lag and took minutes to open. The problem seemed resolved for awhile, but firefox started to not respond off and on, task manager stopped responding completely, explorer crashed, and my computer blue screened. It wouldn't even get off the blue screen after minutes of waiting, so I shut my laptop down manually. I'm positive that this couldn't have been a virus, since I only visited my usual websites, and I have both adblock plus and noscript installed. As for my laptop now, it won't boot to windows vista. I tried the hard drive test and failed. Now my laptop isn't even able to turn off no matter how long I hold down the power button. It's not an old laptop, so I doubt that it was just time for it to die.

I have always been a fan of firefox, but this is just horrible. I don't know if it was firefox's fault but it sure seems like it...

I'm currently on my older laptop, since my other one is obviously dead now. My broken one had vista installed and again, firefox 3.6.8 version.

While in E bay, I buy an item, when I press "Commit to buy", Firefox crashes every time. Then does the report thing and takes me back to the 'commit to buy' page again .... several times it has bought a second item. I have to be careful to exit and restart Firefox. This does not happen with IE.

I recently had Firefox update and ever since the update, I have had problems with it. It is so bad that I have to use internet explorer. Every time I use firefox on any page, it freezes/locks up...it tells me it is not responding. I have to go to the task manager in oder to even close the window. I do like firefox better than IE, so I would love to have this problem fixed.

Hello, I`m running XP SP3, witk no appearent viruses (according Bitdefender and Malwarebytes' Anti-Malware) or hardware problems, but having crash after virtually each exit. After I cleaned cache, temp (maybe sth else as well, don`t remember) dirs and started/exited firefox few times, it didnt crash, bet after few more such cycles problem came back. Any help would be appreciated.

Firefox continually crashes (approx. 6-8 times a day or more) due to Adobe Flash player crashing.

I'm running Firefox 13.0.1 and Adobe Flash 11.3.300.262

I noticed that since the second-to-last update of Flash Firefox has been crashing a lot. Before that Firefox crashed 'only' once a day or so.

Over the past few months I've read just about every thread related to Flash & Firefox and I'm not about to spend hours troubleshooting stuff, trying to disable hardware acceleration, etc, etc. I've done that before when the Flash-crash issue started a couple of months ago. (Also, Firefox is sometimes sending you automated crash reports, so you should have that data.) I would expect Firefox to simply "work" reasonably well, and as of the past couple of months or so, it hasn't.

W.T.F, Mozilla? I've used your browsers (Netscape) since the early 90s and have been quite happy - until recently, that is. As of now I'm having to go back to using Internet Explorer.

I sincerely hope Mozilla can finally resolve this issue as I still believe Firefox could be a great browser if it didn't "fight" with Flash all the time.

It stopped working like 2 weeks ago. I don't know what happened but when I open it I can't use it. I can't type in the search bar, I can't click anything, or go to any website. I can minimize it/close it by right clicking, not by the X or -. It seems to be working but with an error, the little "loading" icon keeps going but doesn't stop:

I've tried everything! I've uninstalled, reinstalled, deleted every other version of Firefox, everything!

Ever since I upgraded to Firefox 4.01, it is like constantly crashing. Since upgrading in the last week, I have 35+ crash reports in about:crashes and none of them show crash signature, as shown on the web page in the crash id section when filling out this report.

I've tried to find a volunteer online during live chat this week but seems no one is there during the times listed. Tried Monday, Tues and yep, today - nada! :(

I've checked the various articles about Firefox 4 and the crashes. I have verified my graphics driver (Intel G33/G31 Express Chipset Family) is up to date. And have very minimal add-ons (as in almost none!) to the best of my knowledge.

Here are a sample of some of the crash reports to see/find the issue : (will list 3 of the 35+ for a sample)

I downloaded the newest version of Firefox, yesterday, and now it keeps freezing. What can be done about this?

Firefox 6.0 My system is Mac OS X 10.5.8

Firefox 6.0 (release) has a memory leak.

Tested with 5 windows and 43 pages loaded and left overnight, it crashed after several hours. Able to fully repro this every time.

I left it for 10 mins after all pages loaded. I opened Task Manager and I can see the Memory (Private Working Set) increasing every few seconds.

FF worked fine before I accepted the latest update just a few days ago. My friend who lives far away said that she also has problems since the upgrade. When I click on the thumbnail to open FF no window opens, all I see is the crash report. Without the window I can't try the self-helps or give a crash ID (from what I understand from reading the options). None of the options in the crash report restore the browser. When I click on one, the box just pops right back up. Other than general slowness of my system and some possible hacking which got someone into my paypal account this week, I've had no other computer issues. (I've changed my email address with PP & changed my email passwords in case someone is accessing my machine through my email...I'm not very computer literate...I don't believe this can happen, yet no other options were presented). Because my friend also experienced this crash issue I think this is totally related to the upgrade & what ever it did to my computer such that FF no longer loads. Please give me steps to fix this issue without FF running--all the self-help techniques seem to assume that I can run FF, get a browser window, utilize the links therein. I can't get a window open at all!

I have tried reinstalling, opening it in safe mode with add-ons disabled as well.. I don't get anything from the crash reports either, as it wont allow me to see it. I have tried everything that I possible could think about..

I'm lost on this one.

whenever i try to watch DivX movies through a streaming website, the extension to the movies are .avi files, only these streams cause my firefox to crash. if i would just let the firefox load itself out of the problem, which i have, it never does until i CTRL ALT DELETE it in the end task manager.

streaming worked fine for .avi files before the new firefox update, so will this error be fixed, or is it something else? and if so how do i fix the problem so i can continue to view these movies online?

I have been using Firefox 5 on the Mac OS X Lion developer preview for a few days now, and Firefox crashes over and over again.

If I have more than 2 tabs open, Firefox can't last more than 20 minutes without crashing. I have submitted multiple crash reports.
