Vista - Firefox crashing in x64

FWIW, I have had no end of trouble getting Firefox to run on my new system. Starts off fine after a clean install/restore but after some time it always crashed and would not load again, and always gave me the same set of error messages - all related to Extensions or Add-Ons, of which I only had 2 I'd put on myself and trusted from XP. Googled my heart out and never found a solution, nor saw anyone else who had encountered this total loss of Firefox. Lots of posts referring to crashes but none about a total Firefox blackout. NOTHING, and I do mean nothing, would fix the problem. I tried all this: run Firefox Safe Mode; removing all addons and cleaned up all the extension entries; Uninstalling and Reinstalling; cleaning profiles; removing all Mozilla folders; deleting all registry entries. i.e. What you'd think would have removed any trace of Firefox on my computer. Because I refuse to use Explorer and don't like Opera that much, I would restore my clean backup and go again, only for the crash to reoccur

Finally, after cleaning the registry etc. etc. I tried installing to a new folder (Firefox instead of Mozilla) and so far so good. Why this works I have NO idea. Wish I'd know how simple that was in the first place - HTH someone else somewhere along the line.

Did you have FF 2.x on your system and are now running FF 3.x?? Are you using Mozbackup? Once you put the FF 3.x profile on, you cannot restore stuff from a FF 2.x profile save. It hoses everything. Take all the FF stuff off and put Minefield on. It kicks ass. Put Mr Tech Toolkit on first so you can turn off version checking for AddOns. I've been using Minefield nightly builds for months on Vista64 SP1 and Vista 32 bit and now W7. It runs great.

No - I was (am) running 3.0.10, and had only backed up my bookmarks via the Organizer and copied my profile manually. I was about to go back to 2 when I got lucky! I will give Minefield a run - thanks.

Think I MIGHT have finally found the culprit for the crashes, though. Today I tried to run my Creative Zen (MP3 player) software to edit my music library. It wouldn't run that particular (browser) area of the software, referred me to some missing registry entries ... cannot find {yadda yadda} ... must be stuff I deleted when cleaning out the Mozilla registry entries. (Why it would link itself to my default browser escapes me, but it must have, because that's all I scrubbed from the registry.) Reinstalling the Creative software didn't restore the entries - I haven't yet gone further with this because I can edit the music list via my file manager (Directory Opus).
