FEBE is a Firefox extension that allows you to automatically back up your Firefox environment and restore it at will. It is a highly customizable tool, allowing you to select exactly what you would like to save and how often to automatically back things up. It can be used to save extensions, themes, bookmarks, preferences, cookies, and more, as well as virtually any other data on your computer, even outside of Firefox. Your Firefox environment will be saved into a .xpi file that can be used to quickly restore everything. FEBE now allows uploads directly to your Box account – you can create backups manually, or schedule automatic uploads at any interval you choose.
To use FEBE, click "Add" and download and install it. Go to the Tools pull down menu in Firefox, select Add-ons, and click on Extensions. Click on Options for FEBE, and go to the Box tab to set the uploading options for your Box account.
