I tried using hotkeys. I had to have clicked the game before i used a hotkey. Otherwise it did what Mozilla said.
For instance
Ctrl+C is copy, nothing was selected so the button didn't work.
Ctr+W is close tab, it did exactly that without selecting Elvenar.
And I forgot the other two but they did not do what Elvenar wanted unless first clicking on the Elvenar screen.
Mozilla Waterfox 37, it is basically firefox but faster for me.
