This is useful if you can't synchronize the two computers' bookmarks using Sync, for some reason. You can also use a bookmark backup file from one computer and restore it on another computer. See How do I set up Sync on my computer? for more information and instructions on setting it up. 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.įirefox Sync is the best way to keep your bookmarks (and other profile data) synchronized between all of the computers you use.
