I can't open a new window. I can't select preferences. I can't shut it down even when I try to force quit. Going to the finder and shutting down does not work. This prevents me from shutting down my computer.

Firefox has stopped working in my computer. I have uninstalled and reinstalled 3 times now, and it will not load up. Many articles online instruct me to clean cookies, etc. but I cannot do anything if the program doesn't load. It does not even show as loaded in my Windows Task Manager. Please advise.

hi about 2 days ago ff stopped working. i type an address into the usual window like i've done a million times, hit enter, and nothing happens. i click on a bookmark, the url shows up in the address window, but nothing happens. there are maybe 3 bookmarks that still work, and all the rest are duds. auto-complete still works, but firefox refuses to take to the address. i get a lot of "flash crashes" (thanks, adobe) so i recently updated flash, and that started the problem. this is why i distrust updates. (for the record, i keep current with firefox updates, even though it is still bloatware that uses 2 GB just to run 3 windows. anyway, any help you could offer would be most... helpful! (not sure why my exclamation points are printing as open-brackets, but hey, whatever, that's the internet) thanks, tim

First thing, why is there no "register button" on the forums, tell your UI guys this IS confusing, not might be confusing, you have to go through this question submission to register at the forums. Been on the Web since I started hosting a BBS in 1988, I should not be confused. I should be browsing the forums right now looking for the right thread to get some help in. Wonder where this will be posted? I don't know, because this is confusing.

As I'm typing this my characters are freezing ever 15 seconds or so. Is there something wrong with the current build? I've had crashing and "not responding" problems for the last month and a half. Have removed all plugins and Add-ons (not cool at all) and then re-installed, twice if you include today. You see, since the last update, which I thought might be a bug fix, Firefox is now using most all of my ram, usually about 3.2 GB of it, no matter if there is 4 tabs or 15 (which I would NORMALLY have in my browsing, so I no there was a point where Firefox had no problem with this). That sounds like a memory leak to me. My question is: Is there something wrong with Firefox right now? Seccurity Essentials and MBAM both say I"m virus and malware free, which would make 4 years of being virus and malware free, I make an effort to browse smart, so I'm pretty sure that's not it. I'm attaching a link to a Screenshot I put in my dropbox of the threads tabs of Process Explorer, what are all these threads? Why is firefox running all these Threads at once. Is this normal? I cannot use Firefox right now, is there something wrong on my end or your end?

Thank you, Adam.

I recently upgraded to 36 and am running Windows8.0.

I opened up Firefox after the update and it worked fine until it suddenly stopped connecting to the internet. It doesn't say that it can't connect to the website, it just sits there with the loading charm circling endlessly.

I can restart my computer and use the "Delete Parent.lock" fix, but it doesn't last for more than about 5 minutes. I also can't untick the box for "Read Only" on the folders for profiles. Rather, I can, but it reverts after hitting "OK" and closing the Properties.

Refreshing Firefox after rebooting my computer worked for about the same length of time, so that fix will not work.

This started to happen two days ago. I'm using Firefox 36.0.1 on my brother's laptop, always using private browsing, and things seem to work fine for 5-10 minutes. After that, the browser won't load or refresh any website at all, it just shows the spinning wheel and/or a white page, with no error messages.

After trying to close and open process again, I receive a dialog saying that Firefox is running already. I can see the process running but I can't close it with task manager. Have to reboot and manually delete the parent.lock file on my profile folder.

Once I can open it, after 5 minutes, it happens again.

What I've tried: Deleted cache, cookies and history. Disabled extensions. Disabled Javascript. Went to normal browsing. Went Into safe mode. Made a new profile. Refreshed Firefox. Uninstalled and reinstalled.

Last seemed to work, installed Adblock and managed to recover my bookmarks. Worked for 1 hour, then it happened again.

Checked for my firewall, there was an exception already. Checked my antivirus, my brother's laptop uses Avast, disabled webshield. No need to check for proxys, don't use them. Everything was working fine till two days ago.


Posting from my desktop computer. My current browser has more plugins and extensions installed. This one works fine. So I'm putting my brother's specs.

Version: 36.0.1 Extensions: only Adblock Plus and Download Helper Plugins: Shockwave Flash and Java all up-to-date. OS: Win 8 64bit Sys Specs (don't know if this is relevant): Intel I7 3,5GHz 8GB RAM

I am running Firefox on Linux Mint 13 Maya. For some reason many of the buttons in Firefox (not on webpages but in FireFox itself) do not respond to mouse clicks. I have tried Safemode, refresh/restore and uninstall/reboot/reinstall. Still the same problem. I have a hard time accessing settings because the menu button is one of those that "depresses" but does not respond to any mouse clicks. Also I can not activate or deactivate plugins because of the same problem.

Firefox within the last month has started freezing every time on a Windows 7 laptop every time I try one of the above actions. I have tried "refresh Firefox", safe mode, uninstall/reinstall, nothing seems to help. Can't open prefs so I have not been able to turn off hardware acceleration. However, I was able to set up Firefox Sync which let me get my bookmarks to another PC and it looks like make setting changes on that PC affects this copy of FF so I <think> I've also tried turning off hardware acceleration. Nothing works. Especially frustrating that the options freeze. Firefox has worked for years on the affected laptop, is there anything I can do except give up and switch to another browser?

Hi, I have gone through all the troubleshooting procedures you suggested to fix the problem of a script running that causes extreme slowness on my computers (I have 3 so it is not a computer issue). It only happens when I am looking at facebook posts in my email, or at least that is when it begins. My firefox is up to date, that is whenever I get an update from you it is installed. Firefox works fine so long as I am not going through my facebook posts in my email. The last time I did the troubleshooting process it cleared and messed up all my settings so I am not willing to do that again. I am looking for a real solution that will not cause a reset to all my settings but will enable me to actually look at my email without the computer creeping along. I have more than adequate internet service, I have AT&T Uverse 12 meg, so it is not my internet connection, I believe it is a problem with an incompatibility between firefox and maybe my email service (AT&T) and/or facebook. The solutions AT&T offered did not take care of the problem either, hence my letter to you. I have also eliminated any unnecessary programs at start-up so I do not think there is a conflict there. Please, what kind of solution do you have now? I did your troubleshooting process in March of this year.

Thank you for your consideration in this matter, Jenifer Stabler

It seems that recently Firefox (perhaps the pop-up notifications) are freezing my Windows 7 machine. I have used Firefox for years without this problem. During the past weeks I notice that system freezes seem to happen when a Firefox pop-up notification appears at the lower right of the screen (e.g. Firefox 38.0.5 is available ...). The mouse will continue to move the cursor on the screen for a few seconds, then that freezes to. I get no response from the keyboard, even CTRL-ALT-DEL and power button fail to reboot the machine; I must remove and reattach the power cord.

Hoping that Mozilla had fixed the problem I updated today to Firefox 39.0, but when a Firefox browser plugin presented a notification in the lower right of the screen the system froze again. I do not have this freeze problem when Mozilla Thunderbird presents a notification in the lower right of the screen (e.g. XXXXXX received 6 new messages).

Using a Macbook Pro with Yosemite OS X. Firefox app won't 'force quit'. I have tried hard and soft restarts, but the Firefox app stops the computer from carrying out command as Firefox won't close. I can't update the Firefox software as the current Firefox app is still open, or delete the app, for the same reason. Cannot use Firefox in Safe Mode (a route to a possible solution in other threads) because I can't access the Firefox menu. Also, can't update Mac software, as it requires a restart, and the technically open Firefox app will prevent this. Help?

When Mozilla support sends a reply to my Hotmail account it contains two links. One is "This doesn't solve my problem" the other is "browse for unsolved questions and help a Firefox User". In the Nightly browser, if I click on either of these the browser freezes. No other tab can be opened; the back arrow cannot be used; the refresh symbol does not work; and Nightly can only be closed from the Task manager. Worse, if it is left open it disables other applications. While the task manager is open, if it is moved, it leaves a trail of repeated copies of itself. If Quicken is closed part of the display remains on the screen. Even using CTL+ALT+DEL to refresh the screen and asking only to open the task manager does not resolve this problem. Am I REALLY part of a Beta test or did you all just skip Alpha and give us anything that looked like it could be called a browser?
