Firefox has stopped working completely

Firefox stopped working after I changed preferences to have it clear history on closing. I have reinstalled 3 times (new version) Will not launch at all. Will not reset Will not open in safe mode. At the very least I would like to salvage my bookmarks. iMac running OS 10.9.1. Anti virus software disabled for this problem

Reinstalling wont do much for this problem, instead you should create a new profile and transfer files from the old to the new.

* [[Use the Profile Manager to create and remove Firefox profiles]]
* [[Recovering important data from an old profile]]
Does that help?

Browser Install Fails, it says "Firefox has stopped working" and it does not install. I cant use your browser.

I had few issues with Mozzilla browser so i uninstalled it completely and tried to re install it again. But when i try to reinstall it , it does not install fully , it breaks half way and says, Firefox has stopped working. I cant install Firefox now. Can you help.

Try this instead:
*Download the full Firefox installer and save the file to the desktop<br>http://www.mozilla.org/en-US/firefox/all.html
*Start the installation with a double-click on the desktop icon
Make sure that your security software isn't causing problems.
Boot the computer in Windows Safe mode with network support (press F8 on the boot screen) as a test to see if that helps.

Since installing 3.6.12, firefox crashes continuously...I have gone back to Windows Explorer because firefox does not run anymore. Upon any actioin in firefox, the screen goes white and freezes and I get an error message saying firefox has stopped working

just about any action in firefox will cause a "WHITE SCREEN" freeze up and then an error message stating that firefox has stopped working. This happens in EVERY sessioin of firefox.

I have had a similar problem with my system. I just recently (within a week of this post) built a brand new desktop. I installed Windows 7 64-bit Home and had a clean install, no problems. Using IE downloaded an anti-virus program, and then, because it was the latest version, downloaded and installed Firefox 4.0. As I began to search the internet for other programs to install after about maybe 10-15 minutes my computer crashes. Blank screen (yet monitor was still receiving a signal from computer) and completely frozen (couldn't even change the caps and num lock on keyboard). I thought I perhaps forgot to reboot after an update so I did a manual reboot and it started up fine.
When ever I got on the internet (still using firefox) it would crash after anywhere between 5-15 minutes. Since I've had good experience with FF in the past I thought it must be either the drivers or a hardware problem. So in-between crashes I updated all the drivers. Still had the same problem. Took the computer to a friend who knows more about computers than I do, made sure all the drivers were updated, same problem. We thought that it might be a hardware problem (bad video card, chipset, overheating issues, etc.), but after my friend played around with my computer for a day he found that when he didn't start FF at all it worked fine, even after watching a movie, or going through a playlist on Youtube.
At the time of this posting I'm going to try to uninstall FF 4.0 and download and install FF 3.6.16 which is currently on my laptop and works like a dream. Hopefully that will do the trick, because I love using FF and would hate to have to switch to another browser. Hopefully Mozilla will work out the kinks with FF 4 so I can continue to use it.
I apologize for the lengthy post. Any feedback would be appreciated, but is not necessary. I will try and post back after I try FF 3.16.6.

Why am I continually getting "Firefox has stopped working" messages?

Seems like constantly, several times a day, I receive the message "Firefox has stopped working" and that Microsoft or Windows is searching for the problem, and then it shuts down. When I open Firefox again, it takes me right back where I left off, with another open window. Also, since running an update a week or so ago, every time I click to open another site I get hit with the "Do you want Mozilla to allow this change?" That didn't happen before. Both are very annoying. I also lost my RoboForm toolbar unless I juggle back and forth the "Full Page" setting after dropping down the open menu bars. I am not, by any means, a computer whiz, so most of the help FAQs are written above my knowledge of computers level. Now when I just clicked "Automatically add" Troubleshooting info, at the bottom of this page, I got a pop up that said " Firefox prevented this site from asking you to install software on this computer". Now I'm really lost! I don't want to reset back to Default because I'll never get back the settings I currently have.

Regarding the message about allowing a change, is there more information about what the change is?
You have quite a few plugins, and they might not all be necessary. To minimize the influence of add-ons while you're troubleshooting this problem, I suggest the following.
Open the Add-ons page using either:
* Ctrl+Shift+a
* "3-bar" menu button (or Tools menu) > Add-ons
In the left column, click Plugins.
* Set unrecognized or rarely used plugins to "Never Activate"
* Consider setting "player" type plugins such as QuickTime, Silverlight, and Shockwave Flash to "Ask to Activate" so that sites cannot run them automatically. As you discover sites you want to allow to run the player every time, you can click the notification icon in the address bar (looks like a small Lego block) and give permission there.
In the left column, click Extensions.
* Remove unrecognized extensions, or disable them
* Disable rarely used extensions (for example, you don't use it daily)
Often a link will appear above at least one disabled extension to restart Firefox. You can complete your work on the tab and click one of the links as the last step.
Hopefully this will help keep Firefox more stable.

Every time I TRY to start firefox 18-19 I get an error message : Firefox has stopped working - close the program and check online for a solution - or - close ..

Every time I TRY to start firefox 18-19 I get an error message : "Firefox has stopped working" - "close the program and check online for a solution" - or - "close the program" this happens TWICE every time I try to start firefox. Eventually after a random number of tries firefox will start normaly. I am useing firefox 19.0.2 now bit I belive it started when I upgraded to firefox 18 but am not sure, it might have been when I upgraded to firefox 19 ... but it has been happening for a very long time and I cannot find any helpfule solutions online.
I have tried a Clean reinstall but it did not help.

Hello,
'''Try Firefox Safe Mode''' to see if the problem goes away. Safe Mode is a troubleshooting mode, which disables most add-ons.
''(If you're not using it, switch to the Default theme.)''
* You can open Firefox 4.0+ in Safe Mode by holding the '''Shift''' key when you open the Firefox desktop or Start menu shortcut.
* Or open the Help menu and click on the '''Restart with Add-ons Disabled...''' menu item while Firefox is running.
''Once you get the pop-up, just select "'Start in Safe Mode"''
'''''If the issue is not present in Firefox Safe Mode''''', your problem is probably caused by an extension, and you need to figure out which one. Please follow the [[Troubleshooting extensions and themes]] article for that.
''To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before opening Firefox for normal use again.''
''When you figure out what's causing your issues, please let us know. It might help other users who have the same problem.''
Thank you.

Certain Firefox problems can be solved by performing a ''Clean reinstall''. This means you remove Firefox program files and then reinstall Firefox. Please follow these steps:
'''Note:''' You might want to print these steps or view them in another browser.
#Download the latest Desktop version of Firefox from http://www.mozilla.org and save the setup file to your computer.
#After the download finishes, close all Firefox windows (click Exit from the Firefox or File menu).
#Delete the Firefox installation folder, which is located in one of these locations, by default:
#*'''Windows:'''
#**C:\Program Files\Mozilla Firefox
#**C:\Program Files (x86)\Mozilla Firefox
#*'''Mac:''' Delete Firefox from the Applications folder.
#*'''Linux:''' If you installed Firefox with the distro-based package manager, you should use the same way to uninstall it - see [[Installing Firefox on Linux]]. If you downloaded and installed the binary package from the [http://www.mozilla.org/firefox#desktop Firefox download page], simply remove the folder ''firefox'' in your home directory.
#Now, go ahead and reinstall Firefox:
##Double-click the downloaded installation file and go through the steps of the installation wizard.
##Once the wizard is finished, choose to directly open Firefox after clicking the Finish button.

"Firefox has stopped working" whenever I open it.

Today I tried to use firefox for the first time in a few months (as chrome wasn't working for something). When I opened it, the Windows "Firefox has stopped working", "Check online for a solution and close the program" or "Close the program" window pops up. It pops up before the firefox window even opens or anything. I reinstalled the newest version and it is still doing it. Can anyone help? Thanks!

I get the "firefox has stopped working" message after closing browser

Hello.
My problem is that when I close the FireFox browser I get the "FireFox has stopped working" message. It's pretty annoying. I've read some other posts here that described a similar problem and have tried some of the suggestions in them including:
A clean install, a browser reset, running in safe mode, unchecking hardware acceleration, disabling extentions and plugins one at a time, uninstalling my antivirus (avast), rolling back to version 23.01 and checking run in compatibility mode that someone claimed helped them. None of this was effective.
It seems like after a computer restart the browser will be ok for 2-4 closings and then it will start with the message on every closing. Also, after I uninstalled avast it was good for 6 closings. Rolling back also gave me about 6 message free closings. But then the messages start and doesn't stop.
Is there anything else I can try? Thanks in advance for any suggestions.

One thing is for sure, and that is if the only page i visit is the Google homepage (not logged in) or this site (mozilla forum), the problem does not occur, ever. I can't make it happen.
If i visit yahoo.com (not logged in) (or ighome.com, logged in), as examples, it happens every time.

Get error "Firefox has stopped working" under Windows 7

I'm running Firefox 3.6.10 (just upgraded, I was at 3.6.9) and every so often (maybe 1-2 days), Windows 7 decides to crash it with the error "Firefox has stopped working". Firefox itself does not seem to be generating a crash id, which is disappointing since that way it would be reported. I run a LOT of tabs, at the moment I have around 100 open. I notice that the CPU usage seems to get very high (it shows 25% for me, but I have a quad core machine so I guess that is 100% of one CPU) as well as memory (1.5gb). It's almost as though Windows thinks that Firefox has stopped responding because of the high CPU usage and decides to terminate it.
I've seen some posts here reporting similar problems, but no resolutions. I also saw a post elsewhere suggesting disabling throttling in Windows but saw other posts saying that had not solved the problem.
Any suggestions on how to fix or troubleshoot this problem?

I have this problem too. Now i'm using win7 64 bit, i installed the newest firefox 6.0.2 and yahoo messenger 11 -> i got this problem. First time i think this is a firefox's error. I decide to use process hacker (a mini tool to manager running process) to find out what is happening and i found this: the program name "YahooMessger!.exe" run a few second and it calls the firefox crash popup lol. I uninstall the firefox and i see "YahooMessger!.exe" auto run in process hacker! ^^ conclusion: i uninstall Yahoo Messenger 11 and delete two folder of yahoo in my username's document (1 of them have the program "YahooMessger!.exe"), reinstall firefox and get out this problem!
So my question is: what is "YahooMessger!.exe", is it a yahoo's part, is it a spyware or virus? Here is the link of this file, i have archived it with winrar http://www.mediafire.com/?lf8tc9fal5rxlup

Firefox has stopped working in Windows 7 but works in Windows safe mode

I am sending this from a different computer on which Firefox works fine. My problem is on a Windows 7 PC -- in the past few days Firefox has stopped working in normal mode but works ok in Windows safe mode. I keep getting a Windows error message that it has stopped working and I will be notified if there is a solution. Of course, I am never notified. I have tried resetting Firefox when in Windows safe mode, as well as uninstalling and reinstalling Firefox, after having deleted all the program folders and appdate. I've exhausted every possible fix I could find in the Mozilla support forums but I still can's solve the problem. Can you help please?

Firefox used to work on my windows 8 machine, now it does not, even starting in safe mode and after un/reinstalling. message "firefox has stopped working".

Firefox used to work fine, then a few days ago it just stopped. When I try to start it, it comes up with a message that "firefox has stopped working". That message comes up over the box that asks if I want to start in safe mode or reset firefox. when i try to close or cancel that message so I can try starting in safe mode, both sets of messages go away.
if I try to start in safe mode using the shift key, the same thing occurs. The same thing occurred after I uninstalled and reinstalled.

Do a clean reinstall and delete the Firefox program before (re)installing a fresh copy of the current Firefox release.
*Download the full Firefox installer and save the file to the desktop<br>http://www.mozilla.org/en-US/firefox/all.html
If possible uninstall your current Firefox version to cleanup the Windows registry and settings in security software.
*Do NOT remove "personal data" when you uninstall your current Firefox version, because this will remove all profile folders and you lose personal data like bookmarks and passwords including data in profiles created by other Firefox versions.
Remove the Firefox program before installing that newly downloaded copy of the Firefox installer.
*(32 bit Windows) "C:\Program Files\Mozilla Firefox\"
*(64 bit Windows) "C:\Program Files (x86)\Mozilla Firefox\"
*It is important to delete the Firefox program to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
*http://kb.mozillazine.org/Uninstalling_Firefox
Your bookmarks and other personal data are stored in the Firefox profile folder and won't be affected by an uninstall and (re)install, but make sure that "remove personal data" is NOT selected when you uninstall Firefox.
If you keep having problems then also create a new profile.
