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.

It consistently redirects to the wrong video.

Excellent extension. Only reason for 3 stars is that it occasionally breaks Youtube. It just redirects all video links to random posts. Doesn't happen always but when it does, it just continues to happen for 20-30 mins which can get annoying.

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.

Ok.

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.

Nice

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

I absolutely love this plug in but at the same time it can break Youtube. Issues with playing a video and it randomly sending you into a loop on some random profile. I really wish they'd fix this problem.
