Firefox 8 crashes on every startup (after upgrade from v7)


Firefox 8.0

This morning Firefox on one my Windows XP SP3 machines decided to upgrade itself to the latest 8.0 version. All well and good, but after the upgrade Firefox worked for couple of minutes and then crashed. Every subsequent attempt to open Firefox resulted in immediate crash. First tried couple of obvious things:
  • Start Firefox in Safe Mode
  • Restart PC
  • Reinstall Firefox
None of these actions helped. Then Started Windows in Safe Mode and Firefox was running happily without any issues. This made it pretty clear that problem was caused by a third party software. Standard Firefox add-ons had to be ruled out as they would not be loaded in Firefox safe mode.

Restarted PC again and checked what processes are starting automatically with Windows. Suspicion immediately fell on RoboForm Password Manager, which runs in a system tray and also attaches to Firefox.
Checked Roboform website (using IE obviously) and surely RoboForm on a PC was couple of versions behind. Upgraded RoboForm to the latest version and issue was resolved.

If you have the same problem, but don’t use RoboForm, check for other software which runs as a standalone application and also integrates with Firefox.

I have been having the same troubles since updating from FF 3.6 to 8.1. Necessary window would not open for me and also FF was always 'not repsonding' I tried uninstalling FF 8.1 and installed FF 7 and still had the same troubles. So I uninstalled FF 7 and reinstalled 3.6. Now things are back to normal and I am able to browse with no problem. Here is a link to downlaod ff 3.6

The new update(8.0.1) solved my problems.

I have a SOLUTION for you guys! (for Windows 7 32 bit and 64 bit)

Please do the following steps:

1. Run firefox in safemode

->Windows Start menu ->Run Dialog ->enter C:\Program Files (x86)\Mozilla Firefox\firefox .exe -safe-mode for Windows 7 64 bit edition OR C:\Program Files\Mozilla Firefox\firefox .exe -safe-mode

2. If successfully runs in safemode, go to Tools->Options, then go to Advanced Tab then you'll see general tab, go below then find the "Use hardware acceleration when available" -UNCHECK IT! then hit ok. Then exit your firefox.

3. Start your firefox normally

- This will also resolve your firefox that hangs most of the time!

This is so annoying. Every time firefox decides it's going to do an update I lose all my plugins (add-ons). Is there a way to get an older version of firefox back and keep firefox from automatically uploading new versions?

just install add-on compatibility reporter. Then you won't have any problem with new FF and earlier add-ons

You can download and install previous v. FF from here like me:

After installing, turn off "auto update" option from settings.

haqy, I have same problem. FF8 crashes, I want version 7 like you suggest. I found the ftp site, but do not know what to do. There are so many files. what do i download? Can you provide some more details?
# haqy 2011-11-16 15:34
You've to choose your o.s. (win32, linux or mac) and than language. for example: win32/en-US.
# cacbg 2011-11-16 17:17
haqy, I go to the link provided by "admin" and download file. It does not give me option to specify o/s, language prior to download. Are these chosen at time of install?
# haqy 2011-11-16 17:39
Nope, the setup file not ask your o/s and language. First, you've to choose from ftp folders for your o/s and language. Than download and install. If your language english with windows7 o/s, go to win32/en-US folder for setup file.

I need to tell you that my o/s is Windows Pro-SP3, US english. Is the link to file that you provided consistent with these details? Thanks.

Yes, the link matches your system and language.
Uninstall Firefox 8 first, then install downloaded Firefox 7 file and disable auto update as haqy suggested.

This is a firefox-8 problem, not an add-on or 3. party software.

Thanks very much for this solution - although I had updated Roboform on one PC, I had not done so on the other. Have now done so and after 10 hours of Firefox 8.00 fails, it works fine.

Run Firefox 8 as administrator and it will work but Roboform will not work in Firefox 8
