Moving bookmarks to another computer


Using Firefox Sync

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


Important: Firefox Sync continuously updates itself as you change bookmarks, so it does not provide a true backup service, nor is it intended to be used as one.


Firefox Sync is the best way to keep your bookmarks (and other profile data) synchronized between all of the computers you use. See How do I set up Sync on my computer? for more information and 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 synchronize the two computers' bookmarks using Sync, 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 named bookmarkbackups folder. Place the bookmark backup file on your transfer media (for example 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.
