Firefox does not open at all! Troubleshooting solutions do not work.

My operating system is Windows XP. Firefox installed a new update two days ago. It caused Firefox to crash repeatedly and was a pain in the bum, but seemed to sort itself out after three restarts and a lot of frustration.

Turned my computer on again today (two days later) and when I double click Firefox, the egg timer shows for about two seconds, but the program doesn't open. Neither will it open if I right click and select Run, or if I open it from the Start menu.

I've restarted my computer, that has made no difference.

I started to copy my profile information and make a new profile, as the troubleshooting guide suggested. However, when I get to the point where you run the Firefox Executable file, I get an error message apologising for Firefox crashing, and offering to report the problem to Mozilla. This has happened three times.

I can't reset Firefox, because it doesn't open.

Apparently uninstalling and reinstalling won't help, and I don't want to lose my bookmarks. Any suggestions?

Thansks!

Try a clean reinstall and delete the Firefox program folder before reinstalling a fresh copy of Firefox.

Download a fresh Firefox copy and save the file to the desktop.

Uninstall your current Firefox version, if possible, to cleanup the Windows registry and settings in security software.

  • Do NOT remove personal data when you uninstall your current Firefox version, because all profile folders will be removed and you will also lose your personal data like bookmarks and passwords from profiles of other Firefox versions.

Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.

Your bookmarks and other profile 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.

See "Creating a profile":

If the new profile works then you can transfer some files from an existing profile to the new profile, but be careful not to copy corrupted files.

See:


If you have submitted crash reports then please post the IDs of one or more crash reports that have this format:

  • bp-xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx

You can find the IDs of the submitted crash reports on the about:crashes page.

  • You can open the about:crashes page via the location bar, like you open a website.

If you can't open Firefox then see:


Try to boot the computer in Windows Safe mode with network support (press F8 on the boot screen) as a test to see if that helps.

Hiya

Thanks for the links. The mozillaZine article deals with Firefox crashing, which isn't my problem. It is not opening at all. The second link is to the troubleshooting guides which I have already followed. It is when I follow the troubleshooting guide that I get the crash error message!

I have two submitted crash reports (interesting, as I only submitted one) and the IDs are as follows:

bp-82589e84-4c4e-458f-a2a1-88e8b2130311

bp-a7a81996-f58f-4e7e-823c-cb2762130311

Thanks!

Ahhhhh! Clean reinstall has worked, bookmarks are intact. Thanks! (Just an fyi - creating a new profile was what was crashing, so that wouldn't have worked.) Thanks for your help!
