@jrob1765 Right! Maybe it is a Mac bug...

I don't think it is a mouse problem. I've used different ones. Including trackpad from my Macbook Pro. It somehow has to do with positioning on the screen. I'va also changed monitors and resolution and still happens.The option I get me most is save as or enter fullscreen and it does enter without me even clicking in it.
The only variable I see is that my Macbook pro is a bit outdated. I might change browser soon.

I have the same problem since today with a new update. It's really annoying...
