quick find pop up when i press shortcut keys like s d z x etc in fireforx on my ubuntu desktop
please fix it

The addon stopped working entirely today without any reason. I have already tried re-installing, but it still does not work.

Does not work. When I click + it only increases the speed by +0.1x. Clicking + again DECREASES the speed by 0.2x!!!!!! infuriating. USED to work, not anymore.

Doesn't work, videos won't play and ad shows after page refresh.

Why did you change the design? HORROR!
Now the control panel is just HUGE and it gets in the way of your viewing! It used to be tiny and inconspicuous ...
It would be better to add the Reset Speed button.

-RU-
Зачем изменили дизайн? УЖАС! Теперь панель управления просто ОГРОМНА, и мешает просмотру! Раньше была крохотная и не приметная...
Лучше бы добавил кнопку Ресет Спид.

Please add an option to go back to the old design

Used to work fine but now makes a deflating sound when speeding up a video

Does not work

I had to disable it since it was causing serious issues to some websites that had nothing to do with youtube. The developer kindly replied saying the issues would be addressed, but I wonder if I can now trust it won't do the same again, with some other website/web app.
EDIT May 2022: still causing issues, and preventing checkout via PayPal to work at all. Such a pity I have to delete this extension permanently because it's a real disaster.

cannot remember playback speed of each individual sites. I want youtube video to play at 1.3 but that speed carries to ALL video on ALL sites

It is not your extension. it stopped working.
I rebooted everything reinstalled , no good. Then I tried the flash player controls and it does not work either. chrome works fine. i think it may be firefox. can you help me out on this

deixou de funcionar no firefox.... já desisntalei e reinstalei tanto o firefox quanto a extensão, mas não voltou a funcionar

Stops working after 1-2 videos. Only way to make it work again is to remove and add it again.
