I have used this for over a year and found it really useful. But since the last update I cannot stop the Video Player Controls from showing up and preventing me from accessing the YT player volume etc. This is a major flaw.
I will disable and check back in a month before deciding to delete it entirely.

It's limited by 720p. I don't know why nobody can fix that

It needs some work on how it processes opening tabs in background. The current version seems to be having trouble displaying the controls, either within or in a control bar.

It enhances video in more types is true and settings page contains so many helpful articles. Yes all are working properly. But needs a more option in settings. When video paused but its cache is loading, then if I have disconnect internet - clicking unpause the video, the play operation runs. Because without internet its only contains the loaded cache. This "loaded cache" called as "loaded background".
So we need in the settings to "block or stop video cache loading" so we can prevent unwanted mass and data usage.

May I ask why you need to access all of our browser activity during navigation since it's only supposed to work on Youtube?

Works great in the beginning but I cant login Youtube when this is enable. Have to disable and re-enable

This is a swell addon, but could you please include an option to drag the pinned video to any position on the screen and possibly resize it to a custom size with the mouse as well? I'm aware of the current options, which are great, but this additional capability would really separate this extension from the pack. Thanks for the great addon! Your others are amazing too.

After the new Firefox v81 update, the plugin doesn't work as before. The videos need to be clicked twice to be played, the cards at the end of videos are not hidden anymore and so on. Please update this if possible, it's a very good plugin for Youtube. Thanks!

worked great when i first installed it, only crashing on a few occasions...now I have removed it as it does it literally every time i play a youtube vid. removed

must have add-on for firfox
edit : it now sometimes doesnt show control bar and cannot change the default set playback quality for video (tldr sometimes it doesnt work)

Really, Really like it when it works. However the menu settings are over the top complex.
Big failure right now is when the video playback is increased followed with a Volume click, the playback is reset to normal and fails to work until the video is reset. This fail is really a trial, since most videos need the sound boosted and increased playback speed.

Volume controls need to be page-global instead of video-focus, speed controls don't work in full-screen player mode.

La instalé en mi viejo PC y estoy seguro que llevó a errór y conflictos continuos a mi navegador firefox...interrumpiendo totalmente la función de este..obligandome a restaurar el software free lubuntu 18.04,reinstalandolo totalmente en el disco duro.

the chat box on live streams is not changing colour... please fix it

It seems since November (Windows 10 update?) extension partially became DPI unaware - Buttons pane too small to operate.
