Great app otherwise, but NEEDS a "read-reciept blocker" or "'seen'-blocker" for Facebook chats. Blocking "... is typing" would also be a VERY good idea. For both the Firefox and Chrome extentions, PLEASE include this. I will rate this app 5 stars and even donate if you have a donation link.

That was the most important feature I was hoping for. Otherwise this app is still pretty decent/amazing, but PLEASE add a "Seen Blocker" for Facebook chat.
