If you use more than one computer on a regular basis — home, work, laptop, ipad, for example — you know what a pain it can be to keep things like bookmarks and passwords synchronized. Enter Xmarks, which is a dead-handy little browser plugin that makes it easy to sync, um, bookmarks and passwords, across multiple machines.
Xmarks handles the bookmark syncing, and it integrates with Last Pass to support secure password storage. Very useful. And Xmarks even works across browsers — Chrome, Firefox, IE, and Safari.
