Firefox crashes on start-up, even in safe mode

Back in March/April 2012, Firefox started crashing for me on start up, possibly after the automatic/remote installation of MS security patches. After that time, I've not been able to start Firefox without it going directly to the Mozilla Crash Reporter. I've tried everything I could think of including safe-mode, uninstall/re-install, uninstall/back-up profiles directory/wipe profiles and all registry entries/re-install. This continues to fail since version 11(?) through 13.0.1. Even Sea Monkey crashes same manner. BTW, clicking on the "Details" button in the Mozilla Crash Reporter has no effect for me. I was trying it to help fill in the Troubleshooting Information box below as I can't get to "Help > Troubleshooting Information" as Firefox doesn't start.

What was the location of the file?

Firefox crashes at start up, even in safe mode

Firefox crashes on start up. Crashes in safe mode as well. Tried steps on articles. Was watching adobe flash player when it crashed first time.

Any other recent crash IDs (maybe some have links to bugs or other posts)
Crash report: [https://crash-stats.mozilla.com/report/index/ba759d32-e684-4f6c-813b-679ce2111005 ba759d32-e684-4f6c-813b-679ce2111005] 
Crash signature: nsSecureBrowserUIImpl::OnLocationChange(nsIWebProgress*, nsIRequest*, nsIURI*)
That one does not seem to give any useful info at present.
Malware is one common cause of crashes, and that may produce variable crash reports, it is probably worth doing full scans with multiple tools/software to try to rule out the possibility of malware.
*See [[is my firefox problem a result of malware]]
Besides trying in safe mode did you also try disabling all plugins whilst in safe mode. (If it crashes before then, are you able to create a new profile and try that ? ) Also if crashing before about:crashes may be entered have you seen http://kb.mozillazine.org/Breakpad#Location_of_crash_reports
Sorry I am not able to give a useful answer at the moment.

I changed Java settings and now Firefox crashes as it opens, even in safe mode; how can I fix this?

I was trying to change settings to access the comments section of Slate.com. Right or wrong, I changed a Java setting from -1 to 2. The setting was in about:config and I believe it involved some sort of max. As I cannot open anything, I am not sure.
When I made the change, firefox crashed immediately, Every time I have tried to reopen, even in safe mode, it immediately crashes again and will not reopen.

Hi pternagy,
Sorry you are having problems.
For future reference. Those of us that mess directly with about:config soon learn how to recover from mistakes and what it is sensible to backup. Occasionally backing up your entire profile for instance can be useful and would have probably given you a quick solution of copying over the file from that backup.
*[[Back up and restore information in Firefox profiles]]
Ok on to the subject of trying to get Firefox back as it was:
Find your profile and the file ''prefs.js'' and rename that. (The renamed file is a potentially useful backup.) Firefox is then forced to regenerate the file and will reset your preferences to the default. You can then re open and use Firefox. Next try to get it back to normal.
Trying to manually edit the file ''prefs.js'' is normally a bad idea. However if it is a single pref change it may be possible to directly edit the prefs.js file (whilst Firefox is closed) to get everything back to how it was before . You have the renamed file to work with. Probably best to test all this out in a new additional profile then you only break additional test profiles not working profiles essential to Firefox.

Firefox won't start (not even in Safe Mode) on Windows 7 x64

I am Running Windows 7 x64 and Firefox 3.6.15.
Since the day before yesterday I am unable to start Firefox. Even in Safe Mode it just won't start.
I click the Firefox icon, the mouse cursor changes to indicate the computer is doing something. After 3 seconds or so the mouse cursor again changes back to its default state. Nothing else happens.
The Task Manager in Windows shows me that an instance of firefox.exe is running, but I see no Firefox window.
Then if I again click to open Firefox, another firefox.exe instance starts, but again I see no Firefox window.
There isn't even a warning about one instance of Firefox already running.
What I have tried:
I have uninstalled Firefox, removed all the Firefox files and folders from c:\users\username\AppData\Local and Roamning. I re-downloaded the 3.6.15 installation package and re-installed.
No change.

I have the same problem.
The only Firefox version working is the 64bit nightly build 6.0a1. No 32Bit version of Firefox works!. Chrome, Safari and Internet Explorer all work well.
Another Problem I have in this context is, that the Firefox Installer hangs in the tidy up step - even for the nightly 64Bit version. I have to kill the setup.exe process but the Installation seems to be completed.
Before my change to Win7 64Bit I had OpenText NFS Solo 14 installed on a 32Bit Windows7 and no Problems.
Is there a solution for this problem without uninstalling OpenText NFS Solo 14?
I need the NFS Server at work.

Firefox crashes all the time, even in safe mode

Firefox keeps crashing, even in safe mode. I've tried updating my graphsic accelerator, disabling it; i've updated all extensions, windows and firefox.

That is a problem with "Constant Guard" from Comcast (PInvokeCalliWorker; bug 684748)

Firefox crashes immediately upon opening, even in safe mode

Completely uninstalled and reinstalled twice. There's no add-ons or any extras whatsoever installed.

Create a new profile as a test to check if your current profile is causing the problems.
See "Basic Troubleshooting: Make a new profile":
* https://support.mozilla.com/kb/Basic+Troubleshooting#w_8-make-a-new-profile
There may be extensions and plugins installed by default in a new profile, so check that in "Tools > Add-ons > Extensions & Plugins" in case there are still problems.
If that new profile works then you can transfer some files from the old profile to that new profile, but be careful not to copy corrupted files.

Firefox crashes after 10 seconds; same in safe mode

Tried opening firefox, it crashed after 10 seconds regardless of which website I opened (this includes Firefox preferences). Same goes for safe mode. Tried updating to most recent version, uninstalling, and reinstalling and same thing occurs. Tried dragging preferences file to desktop to create a new one and nothing changed.

Uninstalled 10.0.1, installed 10.0.2 and tried to 'Launch Firefox' directly from install. Crash. Tried to open in safe mode. Crash.
Tried to retrieve crash report ID, Windows Search tells me nothing matches
"%APPDATA%\Mozilla\Firefox\Crash Reports\submitted" when I search it.
Otherwise I would have provided that information.

Firefox crashes whether or not opened in Safe Mode

I removed several programs of what I thought were bloatware on my PC a few weeks ago, but have not been able to operate Firefox since.
I have tried a System Restore, I have tried uninstalling/reinstalling Firefox 10 numerous times.
When trying to open Firefox whether by usual operation or in Safe Mode, it still crashes.

Uninstalled 10.0.1, installed 10.0.2 and tried to 'Launch Firefox' directly from install. Crash. Tried to open in safe mode. Crash.
Tried to retrieve crash report ID, Windows Search tells me nothing matches

FireFox 4 Crashes When Started (Both Normal and Safe Mode)

When I open up FireFox 4 (both in normal mode and safe mode) it crashes within a few seconds. It is a fresh install of FireFox 4 but I also have FireFox 3.6 installed as well. The report that was given is:

1. You have a pre-release Beta 1 version of what will become Firefox 4 in like 5 or 6 months. Unless you are intending to test it for flaws and report those flaws to help in the development process, don't use it.
2. Did you create a new Profile for 4.0b1, and are you using that Profile with it? ''That isn't done automatically when you install 4.0b1, and those of us who have been doing the "testing" for many years consider a new Profile as the basis of doing out testing.''
[http://support.mozilla.com/en-US/kb/Managing+Profiles]
IMO, Mozilla is making a huge mistake by directly offering these beta versions to the general public.
Also IMO. if you want to play with 4.0b1, use the Portable Firefox 4.0beta version to minimize any conflicts with a currently installed version of Firefox, and to eliminate the need for creating a new Profile for 4.0 Beta #:
Download Firefox Portable Test to your hard drive and double click the '''FirefoxPortableTest_4.0_Beta_#_English.paf.exe''' file. The entire installation (including a new Profile for "Portable") will be self-contained in the \Program Files\FirefoxPortableTest\ folder and won't interfere with an "official" version that you already have installed. Your Profile will be in the \Program Files\FirefoxPortableTest\Data\profile\ folder.
The "down side" is that Firefox Portable won't launch if any other version of Firefox is already running.

I really liked Firefox for the few days I got to use it. This doesn't bode well for future use.

We're sorry to hear that your Firefox seems to be crashing when you open it. Please perform the following steps to give us a crash report ID that helps us find out more about the cause of the crash.
#Press the following shortcut to get a Run window: [Windows] + [R]. This should bring up a window that contains a text field.
#In that text field, enter %APPDATA% and press Enter. An explorer window should open.
#From that explorer window, double-click on the ''Mozilla'' folder, then double-click on ''Firefox'' and then on ''Crash reports''. Double-click on ''submitted''.
#Now, you should see a list of files that contain reports. Go to ''View'' > ''Arrange Icons by'' > ''Modified'' to get the most recent files at the top of the window.
#Open the most recent 5 files with a text editor and copy the IDs.
#Paste each ID into the reply window on the forums.
Thanks in advance!

Firefox 4 Hangs on Exit even in safe mode Win 7 x64

Whenever I close firefox 4 using the upper right "close" button in Windows 7 x64, it hangs in memory. The windows themselves seem to close properly, but I cannot start firefox without using the "end process tree" function in task manager. If, however, I use the firefox menu-->exit, this behavior doesn't happen. Firefox will close normally. This even happens in safe mode. I have tried re-installing firefox to no avail. I have even disabled AntiVir free with no success. I have not yet tried to disable windows defender, but that shouldn't be problematic. Any answers out there? Anyone with similar problems? I run a clean system, and I'm very tech savvy, but this one just boggles me.

Solved? Ok, so I think I fixed this myself. Originally, re-installing firefox after an uninstall (w/ option to delete profile) did not work. Here is what did work for me:
 
-Complete uninstall of firefox w/ option to delete profile 
-Manually delete entire profile under c:/users/NAME/app data/roaming/mozilla (yes, information will still be there even after a complete uninstall of firefox) 
-Update any other mozilla products (for me, Thunderbird... it turns out the older version was somehow sharing plugins and profile directories) 
-Download firefox 4.0 
-Install w/ defaults 
-disable all plugins manually (go to add-ons and select "disable" for each... why are there plugins you ask? well, some things like Adobe reader, etc... will automatically load in when firefox is installed if that particular program is already on your computer) 
-enable only basic plugins (for me, flash, java, and silverlight) 
-change settings as preferred (my changes were all in the privacy settings) 
-close and reopen firefox (I would recommend doing this at every minute step so you can troubleshoot what happened) 
-add plugins/extensions one at a time, reset firefox (option given once a plugin is installed), configure the plugin, close firefox, open firefox, repeat and wash for each plugin... 
-if any plugin/extension causes a hang, disable it. "End tree" in task manager for the hung firefox. Start firefox. Disable plugin. Do not "Restart" firefox at this point, as it will hang. Instead, use firefox-->close. Then, go in and try enabling the plugin, configure it, and the restart. If all is good at this point, leave the plugin. If not, wash, repeat, leave it disabled and move on without it at this point. 
-run your firefox sync 
-enjoy a working copy of firefox. 
The essential point is to CLEAN EVERY POSSIBLE THING OUT and install the bare minimum, then add parts incrementally and determine that every increment works. Simple, straightforward, but not always obvious.
I hope this helps...

XP SP2 FF18 doesn't start, not even in safe mode

Blue screen on start up, even in safe mode, common fixes not working

I did quite a bit of searching for the problem I'm having, and it seems some of the symptoms are common, but none of the various fixes I've come across have worked. Any help pointing to other things to try would be appreciated, as it is getting harder to search for things without finding repeats of what I've already tried. Also, I was going to post this on the OSX 10.4 board, but changes in symptoms (mentioned at the end of this post) are starting to make me think this could be a hardware issue.
The main problem is that my computer boots normally until the blue screen just before the login window should appear, then hangs.
My system: iBook G4, 800 MHz, running 10.4.11, has an extra GB of RAM installed (for a total of 1.1 GB), new hard drive that is less than a year old.
Things I've tried:
Booting in safe mode: No change, still hangs at blue screen.
Removing airport card, and extra ram has no effect.
I've done a PRAM reset
I've done a PSU reset
Checked for file system and permissions errors with Disk Utility on OS CD
Booting into single user mode works fine, where I tried:
fsck -fy, no errors reported
running /etc/rc worked fine for a while
No unexpected errors or problems seen in /Library/Logs/Console/501/console.log, or in /var/log/system.log
I've temporarily moved /Library/Preferences, /Library/Caches, and /System/Library/Caches, /User/Library/Caches, /User/Library/Preferences, /System/Extensions.kextcache and /var/db/netinfo/local.nidb to make sure none of those were corrupted (plus checked preferences with plutil), nothing fixed.
I've double checked the permissions of the root directory.
This problem did not follow an update or installation of any kind. The computer just completely locked up in the middle of using Safari (and just typing in an edit box, nothing with much of a workload) and the blue screen hang happened upon rebooting after shutting down by holding down the power button.
Single user mode appeared to work fine, although I did get single user mode to hang when trying to back up a few GB of files onto a thumbdrive after copying about 90% of the files. And then a new problem came up where afterward, now the blue screen pops up and hangs about 30 seconds after running /etc/rc returns to the prompt (and about 20 seconds after last of it finishes outputting). I've tried clearing caches again but /etc/rc still causes this.
I was going to try to run AppleJack (recommended for checking permissions and clearing caches) after copying the files to the thumbdrive, but of course didn't think to install that until after I had a problem. And now that /etc/rc causes a problem, I don't know how to attach the AppleJack .dmg file other than hdiutil, which needs the /etc/rc to have been run, and also can't remount the thumbdrive to copy any more files over.
After this recent problem, I noticed that now booting from the OS CD goes to the blue screen too and no further. Has anyone else seen such a problem? I've heard of some issues with loose GPUs in the iBook G4, but they seem to mention scrambled or no/black video (video looks fine in single user mode and in open firmware, and up to the blue screen which is clear and bright). So now I don't seem to have an option to try an Archive & Install of the OS (which I was hoping to avoid, due to effort needed to reinstall other software).

Thank you, I had forgotten about target mode. I was able to back up all of my files. I also copied some additional 50 GB of files of the disk as a stress test and the hard drive worked fine and quick (and because it was quicker than retrieving the same files from a network drive to my desktop).
I was hoping to also unpack the Applejack files on my desktop and put them back so I could run them in single user mode without running /etc/rc. However I haven't been able to get my Linux desktop to mount the iBook in Read-Write instead of Read-Only yet (I don't have access to another Mac at the moment).
