Safari users, rejoice! Now you can keep your bookmarks in sync across multiple PCs, just like Firefox users. Xmarks is the tool that makes it possible. Previously a Firefox-only add-on, Xmarks (formerly known as Foxmarks) is now available for Internet Explorer and Safari.

Say, for example, you use Safari at home, but at work you're stuck with Internet Explorer (not that there's anything wrong with that). Xmarks will keep your bookmarks in sync between the two PCs and the two different browsers. It also makes your bookmarks available online from any PC, smartphone, and so on.

Just be sure to check the settings before you perform the initial synchronization, as Xmarks gives you the option of merging or overwriting bookmarks in one direction or the other. You'll want to give some thought as to how the first sync should go.

Unfortunately, Xmarks for IE and Xmarks for Safari lack one key feature: password synchronization. For now that remains exclusive to the Firefox version/a>. Even so, this is a must-have tool for anyone who runs multiple PCs (and/or Macs) and wants to keep a consistent, automatically updated set of bookmarks on all of them.

Note: Xmarks for Internet Explorer and Xmarks for Firefox are also available.
