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 the icon in the task bar is non responsive. This was not happening when I installed the addon.

Edit:
The problem mentioned above is still not fixed.
Additionally:
Now the enabled option "Auto expand video description box" lets the screen jump to the expanded description box instead of staying focused on the video.

Still usable.

Doesn't work.

Doesn't work

My default resolution is 1080p, I want all videos to be played by default in 1080p, even when I watch a individual video in 1440p or 2160p, I want videos watched after that to default to 1080p, but this add-on is not performing that function. When I play a video in 1440p or 2160p, all the videos I play after that also play in 1440p or 2160p.Very disappointing.

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.

Please, fix the shortcut button.

extension is not full potential working.. you cannot click to shortcut. only way to click is open in extension menu and press off and on to this extension. but its only one time usable. after that again this problem occurs. please fix it.

Reduced from 5 to 3 stars due to recent issues. Setting to 8k doesn't seem to do anything if the video is not 8k. Instead of just loading the next highest, it defaults to 720p for some reason. Setting to 4k does not have this problem. Setting to 4k will load videos at 1440p or 1080p if 4k is not available.

Needs to add support for "Premium" quality. YT Premium quality loads videos in vp9 at literally 3x~ the bitrate of regular 1080p. In the cases where Premium is available, non-premium is in AV1 at less than 1 Mbps.

This addon is extremely useful, but has recently started having significant problems which make it much less usable.
About a week ago, the youtube HD options stopped appearing when I click on the icon in my Firefox toolbar, until I go to the addons manager and turn the addon off and then turn it on again.

Can this issue be explained or fixed?

This extension no longer works!!!! No sure what broke it but no matter what I do I cannot get it to work. Some days it would work but then after closing Firefox then opening back up again it would just be broken...
