The add-on would be great, if the shortcuts work properly. Unfortunately, they are either doesn't work at all or just working on add-on settings page. Sometimes they start working on another pages too, for a brief period of time, than stop. Something is broken there.

Please, fix it and it would be 5 stars! (or advise, what might be the problem). I've checked on two different computers with two different accounts - the issue is the same.
