After repair upgrade Firefox (9.0) would not work. I finally un-installed and re-installed it without success. Following your support guidelines I tried deleting my profile with partial success in that with a new profile Firefox would run once then revert back to an apparent crash after 2 seconds (as seen from task manager). After every new profile created it followed this same routine of working just the once. Any help would be appreciated.

Chosen solution

Try a "clean reinstall" of Firefox by removing the Mozilla Firefox installation directory before reinstalling it, as explained in these articles:

If Firefox still crashes after a clean reinstall, try the suggestions in the Troubleshoot Firefox crashes (closing or quitting unexpectedly) article here and, if possible, post a crash Report ID, as explained at the end of that article.
