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, and (optionally) your bookmarks, preferences, passwords, cookies, and just about everything else Firefox offers (it can even backup/restore your entire profile).

Requirements:

Firefox 4.0b1 - 10
