Actually works and not a dud. GG

O taki dodatek mi właśnie chodziło i cieszę się, że go znalazłem

it is good for less Permissions needed

installed very quickly through addon extension, it looks perfect. You do have th resize the window manually if you want to fill the screen. but otherwise a straightforward Messenger app. I can't believe FB doesn't offer one.

1. It's working
2. It opens instantly
3. It's got simple side controls that fades.
4. You can pin it above other tabs if you need to.
5. It's just like improved firefox window for messenger.

simply put... amazing

So far so good, very clean and the fact that is a pop up window it is way better

Exactly what I was looking for. Only wish the browser window icon would also contain the facebook messenger icon instead of standard firefox one.
