There are a lot of people who hate the day when you need to wipe your Firefox profile clean and start from scratch. You know the drill: install Firefox, get your extensions, adjust the settings, import your bookmarks, etc…
This can seem overwhelming at some point but Google recently made it easier with the release of Google Sync. That will take care of transferring your bookmarks, some of your cookies, and your passwords. That is where the Firefox Extension Backup Extension (FEBE) comes in. It will backup your Firefox extensions and settings, and then all you need to do is use Compact Library Extension Organizer (CLEO) to bundle all of the information into one single XPI file that can be installed in any Firefox profile.
These features are only offered for Windows users currently, which is a little disappointing because one of the big features of Firefox is being cross-platform. Hopefully they will be able to support other operating systems in the future so that everyone can enjoy the benefits of these two extensions.
