    Firefox (3.x) has been acting strange for a while, and I'm suspecting corrupted preference files or something like that. How do I reinstall Firefox from scratch, while keeping my bookmarks, passwords etc?

    So basically you just back up the following files from your Firefox profile:

    places.sqlite (bookmarks)
    key3.db (key database for passwords)
    signons.sqlite (passwords)
    cookies.sqlite (cookies)

    Remove Firefox along with the profile, download and reinstall a fresh copy of Firefox, then run Firefox for the first time (creating a fresh profile).

    Then it's just a matter of copying the backed up files into the new profile, replacing those already there.

    Correct. You could even try *just* deleting your profile and preferences and then restarting Firefox to see if that fixes the problem, without redownloading.

    Yes, but remembering to rename the existing Firefox folder first so you can always revert.
