Says I can choose 144p as default but it only goes to "Tiny" which is 360p.

Extension is broken.

Opening a video with this enabled causes the whole page to scroll down 1 line automatically, cutting off the top of the video. This means that if Im playing a game with autoplay on my side monitor, I have to alt-tab for every new video just to scroll back up.

THe PC version works well enough, no complaints there. But the Android version for Firefox (84.1.1, Build 2015781795) is useless since I can't find any way to change the settings.
And since it looks like the developer has abandoned this and there's no support on his webpage, my 2 stars are being generous.

Beeld kwaliteit is goed , maar het stop op de haverklap. Jammer.

It works just fine most of the time. But sometimes it automatically downgrades the quality setting, and if I try to set again my desired quality, the YouTube video player begins to blink and I have to either reload that YouTube video webpage or restart the web browser.

Takes me to posts for some reason, when I click on a video

Please support - playing youtube video in background

Replicates theater mode and full screen mode from Youtube. The only useful feature is auto quality change, but takes forever to load. Doesn't work for non-SD videos.

Seems to be totally broken. Youtube loads a strange blog view that constantly jumps up and down all the time. I only wanted to stop the autoplay feature in Youtube and show videos in 1080p by default.

When I open a YouTube video link it changes the resolution (does what it proposes). But when I open the YouTube homepage, it redirects me to a random YouTube post and keeps reloading the page. So I can't use YouTube's homepage

Apparently this bug is at least one year old, deducting from old comments.

Hello, and sorry for hte bad news. but. When I tried to use your addon I expected to improve the video qiuality on YouTube. For example, by default YouTube gives ne 720p, but I want to watch in the highest definition. So, I did this: I clicked your addon's and there was a dropdown menu, and I saw: Vieo quality, Video size, Video speed and so on. So, I chose Video quality > and it did not help (the video quality is still 720p). So, I tried "Video quality > Large" and the video is still 720p.
What am I doing wrong? I want to watch in the best quality, and i do not want to specify 4K or 1080p, but I just want the best quality. Why is it not working? ''Large'' and ''highres" do not help. Please, fix your add-on.
I will delete your addon, and i will reinstall it after you write a reply with the words ''Click Highres' and you will get the highest possible resolution''. Sorry again for the bad news. I could have given 1 star because it does not help, but I want you to know that you can have 5 stars if you fix it. Latest version of Firefox, no antivirus, updated Windows 10. ps Maybe my YouTube Classic addon is causing the problem?

For some reason I was not able to save any settings.

after install HD, ADs starts play on youtbe. Maybe dont coop with AdBlock.

Please fix this bug.
