For a long time I was running Firefox 3.0 just fine, until a few months ago when every time I tried to open it, it froze up and I had to shut it down. I removed it and installed Firefox 2.0 which was fine for a while but I would really like to start using 3.0 again. Does anyone know what the problem could be? I've tried uninstalling and reinstalling, deleting my Firefox profile, etc. I'm not really that tech savvy, but I'll accept any help. Oh, and I'm on a PowerBook G4.
