Hi. Will you add shortcuts to handle speed?

i have the youtube+firefox bug combo where the sound volume always is maxed out no matter what. i have tried a few add-ons before and this is the only which manages to actually have an effect on youtube videos volume. By setting the plugin volume at 10 % i obtained my wanted youtube volume (which is different as it is 44 %). i intend to up the note to 5 stars if somehow, someday the add-on volume happens to match with the actual volume result.

i am reporting a bug
when i open a video with expand option ,page going down 1 line automaticly .can you fix it

5 stars if video speed works on embedded videos.

This is one of the best addons for youtube ever. What is missing now is the ability to enable HFR 60. But lately as already reported, the addon sends you to community posts randomly and it remain stuck in refresh loop.
