So it says nowhere if this works for something else than a MAC. So I'm not gonna go through the trouble of signing up if I don't know before hands if it's working for windows and if it's free.

Since I'm here to give a real critic I still signed up :)

It's amazing! You should make it clear that it is a browser extension though. And is it backed somewhere or does all my data dies when I reset firefox?

Also I don't really like that I can't browse through what I saved through the sidebar.
