Foxmarks, the popular bookmark syncing service for Firefox, has now come to Safari. The service is designed to make it easy to keep your browser bookmarks synced when using different computers, by linking each browser to your own online repository. It was previously limited to Firefox, but the most recent version now includes support for Safari as well as Internet Explorer on Windows.
While Safari users have previously been able to sync instances of Safari on different Macs with MobileMe, Foxmarks allows you to sync not just Safari on different Macs, but all three supported browsers (Firefox, Safari, Internet Explorer) on both PCs and Macs. So, for instance, if you're one of those poor folks forced to use a PC at work, Foxmarks will keep your Firefox bookmarks there synced with your home Mac's copy of Safari.
Unsurprisingly, Firefox is still the best supported of the three. For instance, password syncing is only supported on Firefox. And, as of yet, the Windows version of Safari is not supported. Nonetheless, if you want to get your bookmark sync on, the newest version of Foxmarks looks like a winner.
The Foxmarks plugins are free downloads from Foxmarks; the Safari version is Leopard-only.
