not sure if this addon changes youtube playback resolution to hd like it promises or not.
reason is, because it took me under 10 seconds to remove this addon, because it forces me to use that theater mode when videos are not in full screen mode.

if i want to concentrate on video itself, then i put it on FULL SCREEN, but when i want to look at other parts of the site like recommended videos or comment section. then i want the video to be in the small compact size and stay like that until i say otherwise.

Redirects randomly.

On every new Firefox update this add-on gets broken and redirects randomly on Youtube, breaking it completely.

При заходе на главную страницу YouTube, это расширение перенаправляет на разные левые ютуб-каналы и врубается циклическое обновление страницы. Это очень похоже на мошенническую монетизацию - накрутку трафика! И такой прикол ребят происходит уже как минимум год. Я не понимаю как вообще это расширение могло попасть в рекомендованные???

When go to the YouTube homepage, this extension redirects to random YouTube channels and cuts in a cyclical page refresh. This is very similar to fraudulent monetization - traffic cheats! And such has been going on for at least a year. Proof - https://support.google.com/youtube/thread/4029968?hl=en I do not understand how this extension could get into the recommended ones???

The add-on behaves as malware. Constantly refreshing the page without me having done so. The user settings don't reflect on the website. For example, selecting "Normal" for video speed, will not save as a setting and automatically go back to x2. Until the creator of the tool fixes the bugs, don't bother adding this feature to your browser. Just find a different one.

bugou meu youtube e fiquei sem conseguir assistir vídeos, tive que excluir.

worked good for a day then it sends me to a community post each time I try to go to the YouTube homepage and it just refreshes over and over and over until I either close the tab, search for a video from Google, or have a direct link.

glitches out and takes me to a community post on a never ending loop

I love this addon but it now causes youtube to redirect to channel posts/pages and I cannot stop it. Will need to disable until this is fixed.

After using this addon for some years, all of a sudden youtube.com redirected to a post on a page from a channel I have visited in the past. The page was hanging on this post and refreshing all the time. Couldn't solve it by deleting cache, cookies temp etc. Opened youtube.com in MS Edge and no problem occured. Restarted FF in save mode, without addons enabled! No problem with youtube. So I disabled all addons and one by one enabled them again. Found out that 'Youtube High Definition' was the problem of the redirecting of youtube.com homepage. I removed the addon from FF.

When going to youtube.com - instead of the home page, I get the latest Community comment from one of my subscriptions that I rung the bell on. The comment is a never ending loading page and I can't interact with it. After disabling the extension it fixed the issue. I'm posting this here to find how I should report this.

Causa error en la página principal y no termina de cargar.

When this extension is enabled, Youtube constantly reloads, showing what appears to be some random video. There's no getting away from it. Disabling the YT-High-Definition extension eliminates the problem. This extension makes Youtube completely unusable.

We have to log us with google to use this extension ???
Not acceptable for me
