Small, simple, no restart required and it does what it should. Very good :).
Only one thing: It doesn't work with e10s until now. I can't open links in a new tab or in a new private tab if this add-on is enabled.
Edit: Oh, okay, thanks for that info. I leave the note here if someone else is experiencing the same issue. But as e10s is in development it's still completely worth five stars ;-).
This is known issue about e10s:
