i opened firefox just now, and all my settings, favourites, everything is gone.
i am using FF 1.5.0.4
also, i cant bookmark anything. this happened once before too and i had to reinstall that time to fix the problem. can anyone tell me why this is happening and how i can stop it from happening again?
Thanks

are you in your firefox profile?
that has happened on the past to me, couldnt find the solutionj

dont know about profiles, never seem to use them, I.

Click Start -> Run -> firefox -pf
Make sure that you start with the default profile...
