Foxmarks, one of my favorite add-on which backups your bookmarks and password, suggests tags is changing it’s name to xmarks and adding new features.

The features of xmarks are –

Smarter Search

Xmarks will highlight the 3 top sites in your Google results based on how many people have bookmarked them. Simply move your mouse over the site info icon to learn more about that site.

Site Info built into your browser

Click on the Xmarks info icon in your location bar to see detailed information about the site you are on, and discover other great sites just like it.

Sync and Backup

Install Xmarks on each computer you use, and it seamlessly integrates with your web browser and keeps your bookmarks safely backed up and in sync.
The Xmarks browser add-on is coming soon to Internet Explorer and Safari.

Adding new features is great but why the name change?

Well.. The add-on is now not a Firefox only add-on, it’s compactable with both Internet Explorer and Safari. The name Foxmarks links it with Firefox. This might be the reason for the change of name.
