Are you in need of a quick and easy way of backing up your Firefox bookmarks? If you are, look no further than the Foxmarks extension.
If you use Firefox on more than one computer, you’ll want Foxmarks. Install Foxmarks on each computer, and it will work silently in the background to keep your bookmarks synchronized. As a bonus, log in to my.foxmarks.com from any computer anywhere to access your bookmarks.
Out of all the alternatives out there, this one rates, at least, in my personal top five. They have been around for a while now, I have never heard a complaint about them and it is totally free. How can you say no to that?
