some shit resets FF and Thunderbird
 

the last 2 days my pc froze up 2 times, 1st time reboot: Firefox bookmarks and setting were all gone, it started up like it never has run before, pretty fucked up. 2nd time this happens, i rebooted and start up Thunderbird - All my email adresses and emails are gone, this fucking thing also starts like it has never been running before... i ran spybot and another program and it found some kind of *zilla.dll file i dont know exactly anymore how its called but it looks like its some shit that flushes out all mozilla programs, wtf. Anyone ever heard of this? Anyway its gone now.

Oh btw where the fuck are the email addresses setting and mails being saved from thunderbird? Because i find it hard to believe they are all deleted i just need to import them again.

Check in
C:\Documents and Settings\{your name}\Application Settings\Mozilla\Firefox\profiles\

Thunderbird I believe is in
C:\Documents and Settings\{your name}\Application Settings\Thunderbird\profiles\

yep found them, thanks
