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...

Doesn't work on Firefox Android (even before the September 23 update)

Doesn't do anything on Firefox Android after the latest update of this addon.

Before September 2023 this extension worked a most of time normally (but occasionally i saw YouTube in wrong resolution - i closed Firefox and stopped it forcefully via operating system settings and started again - the extension worked again). After a middle of September the extension totally not working. When i open Firefox menu and Extensions submenu and tap to YouTube High Definition extension - nothing opens! Reinstall extension did not help, reinstall Firefox, reboot and reinstall Firefox - did not help (Google Pixel 4a, Android 13)

Partially stopped working on all of my devices about 1-2 weeks ago. Settings do not show up when clicked on the icon in toolbar. Speed setting only gets applied if set to 2x. Doesn't work with 1.25x or 1.5x. Quality settings is also broken. Video Subtitles set to "on" doesn't seem to work either. Settings used to apply immediately after the change, now I need to refresh the page.
It still works just fine with 109.0.0 version. I had to go to the add-on page, click on "See all versions" and install it. In settings of the addon I disable the update feature to keep it at this version.
Keeping 2 stars until a fixed new version gets released.

The last update broke a lot of functionality. Defaulting to 1.5x playback speed does not work. Quality settings are inconsistent. Used to be great but no longer does the things it should.

Version : 118.0.5 (22 septembre 2023)

Ne fonctionne pas correctement depuis la dernière mise à jour, l'add-on semble planter.
- Options inaccessibles
- Configuration non prise en compte

Pour rétablir temporairement la fonctionnalité, il suffit de désactiver/réactiver l'add-on dans le gestionnaire d'add-on, mais cela ne résout pas définitivement le problème.

Can't open the option dialog box. ( 118.0.5 )

After the update it stop working a few days ago. I can't even enter the configuration page.
