"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.foxcloud.com from any computer anywhere to access your bookmarks."
This is a very kewl plug-in, it works with both Windows and Unubtu's FireFox.
