Rated 3 out of 5 stars

Nice addon, I like it. But there is a serious bug (but safe, not dangerous).

I use 2 monitors. When used on 2nd (bigger) and I try to maximize it, FF automatically goes to main screen.

This review is for a previous version of the add-on (0.9.0.3p). 

I'll check it.

- I'll check the 2nd monitor thing. tks!
