Can't open Firefox 8.0. It crashes immediately.

more options

I couldn't open Firefox. It would instantly crash - a window would flash and then I would see the Mozilla Crash Reporter . I restarted my computer. It continued to instantly crash.

I went online and downloaded the most recent version of Firefox. Just as it finished installing a window popped up with some kind of an error, I closed out of it and did not see the Mozilla Crash Reporter.

I un-installed Firefox. Went back to the website and downloaded and installed the latest version of Firefox again. This time it installed without problem, but still crashed instantly when I clicked to open it.

I couldn't test Firefox in safe mode because I couldn't access the top of the Firefox window, seeing how no window came up. Then I saw that you can start Firefox in safe mode by pressing shift and did that. The Firefox Safe Mode window popped up and I checked all the options ("Disable all add-ons", "Reset toolbars and controls", etc.) and clicked "Make Changes and Restart". The window closed and the Mozilla Crash Reporter popped up. I started Firefox in safe mode again and clicked "Continue in Safe Mode". Finally, the Firefox window came up!

Now if I could just get it to work outside of safe mode...

Create a new profile as a test to check if your current profile is causing the problems.

See "Basic Troubleshooting: 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.
