Move Thunderbird Address book to another profile

Thunderbird can have multiple profiles on one account in XP! Just make a new profile, overwrite it with your old one. Profiles are created under C:\Documents and Settings\username\Application Data\Thunderbird. Note that username is your Windows user profile name and Application Data folder is a hidden folder. Switch to it by using [C:\Program Files\Mozilla Thunderbird\Thunderbird.exe -p] at the RUN prompt (hit Windows Key + R), this will load the profile manager I believe and you can then switch profiles there. Once you import the old profile over the new one, you can then either EXPORT the old one (to import it again into your proper profile), or use mozbackup to back up ONLY the address book, and then have it restore it to the proper (probably named "Default") profile.
