Great extension, one thing... Rated 4 out of 5 stars

There's an annoyance under Linux (I'm using Ubuntu with GNOME), where you need to hold down the right mouse button to see the menu and let go on the item you want - the menu closes as soon as you let go.
Other than that, kol hakavod! great extension, really useful

This review is for a previous version of the add-on (1.0.4.56).
