Sync History with FireFox, IE, and Safari.

The only feature missing from XMarks that I loved from other addons is the ability to sync history from my browser. This allowed me to move from my browser at home, to my browser at work, to my browser on the road, back to my browser at home...and the history of all my activities was sync'd so it appeared as though I accessed sites from one machine.

This is a very very useful feature in that it allows me to know exactly which sites I have recently visited no matter which machine I am using, and my browsing activitiy is always up to date everywhere.

If this feature were implemented in XMarks, I would never need another addin for sync'ing browser data ever!
