FEBE

FEBE (Firefox Environment Backup Extension) allows you to quickly and easily backup your Firefox extensions. In FACT, it goes beyond just backing up -- It will actually rebuild your extensions individually into installable .xpi files. Now you can easily synchronize your office and home browsers. FEBE backs up your extensions, themes, bookmarks, preferences, passwords, cookies and just about everything else Firefox offers (it can even backup/restore your entire profile). You can selectively restore only the items you need. For instance, you may just want your bookmarks Restored and leave everything else as it was.
