Ask Tim:Synchronize my Firefox bookmarks to another computer
Foxmarks is a Firefox extension that allows you to synchronize your Firefox bookmarks to another computer. If you are able to run Firefox at work and want an easy way to keep your bookmarks in order then this is for you. Foxmarks requires you have an account to use it. The account is free and allows you to use it virtually anywhere you have Firefox and Foxmarks running.
The Foxmarks Bookmark Synchronizer automatically synchronizes your bookmarks between two or more computers running Firefox. It also lets you access your bookmarks from any computer anytime via my.foxmarks.com.
