good

Seems to have stopped working. Used to work great, not sure what has changed but needs an update.

This add-on doesn't work most of the time. HD icon just stops responding and also the add-on itself. This happens several times per day. Restarting Firefox doesn't help. The add-on only starts working again if I disable it and enable it, which is annoying to do. Then it works for some time and stops working again. I'm using Firefox 119.

Using it for a long long time. Sadly, since the last update and as mentioned by others, I have to disable and enable it again everytime I start my browser, otherwise it's not working.

After doing so, it will work until you fully close the browser.

With fixing this, I'll give it a full 5-Star because it's just so usefull.

Every time I start the browser I have to disable and then re-enable the add on, otherwise it is non responsive anymore.

Doesn't work.

Doesn't work

This has worked for me in the past with intermittent issues setting the playback speed. The September update completely broke it for me. I am using this with Firefox on Android.

On mobile it's awkward, you need to click and scroll 3 times to press the add-on button, it's less without the extension in YouTube.
