Firefox automatically creates backups of your bookmarks and saves the last fiveten backups for safekeeping. This article describes how to manually back up your bookmarks, and replace them with a backup.

• If your bookmarks suddenly become unavailable in Firefox, see Lost Bookmarks for troubleshooting information.
• For more about using bookmarks, see How do I use bookmarks?.

Moving bookmarks to another computer

Using Firefox Sync

You can use Firefox Sync to move your bookmarks from one computer to another.

Firefox Sync is the best way to keep your bookmarks (and other profile data) synchronized between all of the computers you use. See What is Firefox Sync? for more information and How to sync Firefox settings between computers for instructions on setting it up.

Using a bookmark backup file

You can also use a bookmark backup file from one computer and restore it on another computer. This is useful if you can't Sync the two computers, for some reason.

The bookmark backup file can either be a manual backup (see above) or one of the automatic dated backups located inside the Firefox profile folder bookmarkbackups folder. Place the bookmark backup file on your transfer media (e.g. a Flash drive) and copy it to the desktop (or any location) of the other computer. You can then restore the backup from the Firefox Library window, using the Choose File... option, as described in the Restoring from backups section above.
