I love this extension! One of the few get it and forget it extensions I've had for years. Never failed me.
It synchronizes Wired Marker and Read it later (pre 2.0) links too.
I do have to say that the software for IE just doesn't work. I don't know why they keep saying it's compatible because it has never been and they haven't fixed it.
