>v2.1: Add icon for dark theme.
How to enable them?

Works like a charm!

Does what it's supposed to. Only closes current window and leaves others open like it should.

Is just what I want.

Well, this with the other "Maximize" and "Minimize" + "Hide title bar" Addons, you are good to go on Linux mint, no more ugly while using themes, because of the title bar.

Ok, it does what it has to, fast.
But, it would be more interesting (and more usefull!) to create restart button which will work in Web extention format.
