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.

upon startup, ff19 crashes in both normal and safe modes. I've disabled all add ons and extensions.
XP Pro sp3.
It started crashing occaisionally, then increasingly more often, now, upon startup.
I tried reloading ff19.
I can't start ff with the -p command.

its not correct crash id.
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 with '''bp-''' into the reply window on the forums.
Thanks in advance!
You can find more information and troubleshooting steps in the [[Firefox crashes]] article.

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.

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 on startup - opens normally in safe mode.

I've attempted to uninstall and reinstall.

Hello Hokie4Life, disable graphics hardware acceleration in firefox.
copy the next bold '''firefox -preferences''' and paste it in your win 7 run command
(if you have NOT enable the "run command" in your win 7, go from : right-click Start Button > Properties > click Customize > in "Customize Start Menu" dialog > Check [v] the box next to "Run Command" > click OK. Now the Run command will be displayed on the right side of the Start menu)
Now the Firefox ''Options'' window will open (with Firefox closed of course) > 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]]
Thank you.

At odd times I will get a second instance of Firefox startup. I have run avast av, spybot, malwarebytes, both in normal and safe mode and nothing has been found, any ideas?

That second one sounds like malware.
Do a malware check with some malware scanning programs on the Windows computer. 
You need to scan with all programs because each program detects different malware. 
Make sure that you update each program to get the latest version of their databases before doing a scan.

As a test, start your '''Computer''' in safe mode. Then Firefox.

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
"%APPDATA%\Mozilla\Firefox\Crash Reports\submitted" when I search it.
Otherwise I would have provided that information.

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 crashes when opening PDF, Word and other files

Recently, Firefox stopped being able to open PDF files within the Firefox program. It crashes whether one tries to have it open the file or just download it. The same occurs when trying to open a Word doc. It does this in safe mode too. Since I am studying for a college degree and use these features a lot, I've had to stop using Firefox. This is a problem, because my university uses Firefox for its classes and other programs aren't as compatible. I've tried EVERYTHING suggested on line, both in Firefox help pages and in user pages. Nothing works.

Fix the [http://browser.iyogi.com/firefox/firefox-not-opening-pdf.html '''PDF not opening in Mozilla Firefox'''] issue by reinstalling Adobe Reader. You need to uninstall Adobe Reader and re-install it to get the issue fixed. It is important to uninstall all versions of Adobe Reader that you may have in your system. Also, take care of installing the latest Adobe Reader for the browser.

Firefox crashes when starting up, does work in savemode.

Firefox crashes most of the time when you start it up.
I've already done a whole lot of things, like:
-updating everything (firefox, plugins, addons).
-removing addons
-disabling / turning off plugins
It does NOT happen in save mode, so that makes you wonder.
I think it has something to do with one of these things:
- I updated Shockwave for Director (adobe), but the older version is still visible as a plugin. I cannot delete this plugin, though it is not installed on my computer anymore and it has no use whatsoever. I can however turn it off to see if this does the trick. It does not help, but maybe really deleting it does help? I don't know because I can't delete it.
- FireFox runs in SandBox by Avast! Sometimes it does seem like this is the problem, but sometimes he still crashes even though I open FF without SandBox.
- it does seem like hardwarespeed-up has something to do with it. But I'm not sure.
My questions: does anybody know how to really remove the old Shockwave for Director plugin?
Is it possible this is caused by sandbox avast?
How can I establish the hardwarespeed-up being turned off? I can turn it off, this does seem to help: it won't crash. However, when I open FF again, it is being turned on again.

Try to disable hardware acceleration in Firefox.
*Tools > Options > Advanced > General > Browsing: "Use hardware acceleration when available"
*https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes
*https://hacks.mozilla.org/2010/09/hardware-acceleration/
If it does work in Firefox Safe-mode then disable all extensions (Tools > Add-ons > Extensions) and then try to find which is causing it by enabling one extension at a time until the problem reappears.
Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

Firefox crashes when opened through the option "Safe Run for Websites" through Kaspersky Internet Security 2012

Safe Run for Websites in Kaspersky Internet Security 2012 is for browsing websites without the attack of phising sites from storing the date or key strokes. While accessing my online bank account through the said safe run, firefox crashes with an alert msg. by Kaspersky saying "could not initialize the application's security component. The most likely cause is problems with files in your application's profile directory. Please check that this directory has no read/write restrictions and your hard disk is not full or close to full. It is recommended that you exit the application and fix the problem. If you continue to use this session, you might see incorrect application behaviour when accessing security features." How to solve this technical problem? If anybody has a solution, kindly send the same to my email ID : [email protected]

Kaspersky 2012 not compatible with Firefox 9 yet, can you also notify Kaspersky Techsupport and Kaspersky forum about this issue?

* http://support.kaspersky.com/helpdesk.html
if the problem is Kaspersky related, they will fix it through patch via database update

Firefox crashes when starting up on Win2k3 Terminal Server

Firefox 3.x works, however after upgrading to 10.0.2 it will crash whenever starting up.
Platform: Windows 2003 Terminal Server with Citrix.
We have excluded the firefox.exe from the ctxhook and it doesn't help (we know this fixes crashing on startup on Xendesktop deployments).

Thanks for pointing out that crash-stats website. DgApi.dll is Digital Guardian by Verdasys. Essentially monitoring software that the company uses to make sure users are not doing anything they shouldn't. Disabling that fixed it.

Firefox crashes, Firefox crashes when loading certain pages and Firefox crashes when you exit.

I have listed the problems and solutions I have try at here:
