If you have a lot of bookmarks and always need your bookmarks on hand then Xmarks is the perfect fit and now that it supports other browser platforms, you won't have to give up your bookmarks when you switch over to another browser or another PC. The only downsides to Xmarks is the fact it can take a long time to sync bookmarks and on rare occasions, it won't sync at all. But for how much time this can save you, the downsides are minor. On a side note, Xmarks is not compatible with Firefox 4.0 Beta 1 even if you do disable compatibility check, it will not sync your bookmarks.
