What is Foxmarks?
Foxmarks keeps your bookmarks automatically synchronized between two or more computers. A simple wizard guides you through the startup process. Foxmarks works silently in the background. As a bonus feature, you can access your bookmarks from anywhere via my.foxmarks.com. It's simple and solid. If you are a die firefox user then this is for you.
If you haven't already got it I highly recommend downloading Firefox 2.0!
