A bookmark synchronizer with profiles and secure password syncing.
Pros & Cons:
Xmarks is fairly hassle-free and also has a lot of features. One feature that gives Xmarks an edge over the competition is that it has secure password syncing. Another great feature of Xmarks is the ability to have different profiles for different computers/browsers. This allows you to have only certain bookmarks go to certain places. Nonetheless, I have been running into issues with the beta version in Google Chrome syncing with Firefox because the browsers handle bookmarks differently.
Since Xmarks is just a browser extension it can run on many different operating systems. If you sign in to your Xmarks account, you can view, edit, add and delete bookmarks from any browser by going to my.xmarks.com.
Overall I would say Xmarks is one of the best bookmark synchronizers. (NB: Some features may not be available in all browsers, check the chart at http://download.xmarks.com/download/all for the differences.)
