I tried it on android cause firefox crops youtube videos. It crops the video too or show it in a stamp sized window in a corner of the screen.

This used to be a good addon, and lots of it's features are super useful, but it CONSTANTLY redirects you to a random community post instead of whatever video you click, this happens daily for me at least half a dozen times, I'll gladly change my review once this annoying (and judging by all the other reviews, extremely common) bug is fixed.

It consistently redirects to the wrong video.

A bug report:

Whenever I try to change the clip resolution to anything other than what's set by default in the add-on, the resolution gets reset to the add-on settings. After disabling the add-on I can successfully change the video resolution to the desired one. I'm running uBlock Origin as well.

this AdOn is hardly usable!

Absolutely no setting options in the app, nothing at all. youtube movie windows are enlarged, but I don't want that because I want to decide for myself how big the window is. There is no possibility to set the HD in the app, no you have to do that in the video. Too many inconsistencies, therefore not usable, uninstalled again! Because I decide which settings I want to have and not the one who offers the AdOn, something like this is not possible!
And as I see, no update for 3 months, that explains a lot!

just breaks youtube. no videos play, all videos just go to a profile post about covid.

too bloated. I wanna set HD settings, not have it mess with my custom per channel speed settings

Breaks linkage, clicking on youtube video links goes to notifications/comments for unrelated videos. Worthless.

Utilizava o savefroom, depois que atualizou já era não consigo mais, instalar e usar, no meu ver é igual os outros navegadores, e enche muito memória.

ne fonctionne pas.

Every times I visit youtube, it keep refresh youtube page.
