I used to use 32-bit Windows, so I currently use 32-bit FireFox. Can the profile be transferred to the 64-bit version?

Since Firefox places the profile information in your user profile, this is entirely independent of bit-ness. So your profile should work just fine.


to easily backup/restore FF profiles you could use MozBackup... http://www.mozbackup.org/
