Works fine but like Firefox user 12726217 said its now giving "Playback isn't supported on this device." errors or nothing at all(just a black area that you cant interact with), but it seem to mainly be on embedded videos, sometimes video works after several refreshes, but like 90% of the time it gives the playback error or its just a black area. Disabling the addon makes videos load with no issues.

great and useful extension if only it doesn't cause interruptions. it takes seconds before the video loads and triggers "experiencing interruptions?" popup from youtube

Proprietary but no bigger/better toolbox available

Good extension, BUT: recently YT won't load video player while this extension is working. I'm not sure who's to blame for this, leaving review because I wonder if other users have the same issue.

Recently the automatic video quality selection has stopped working.

This is a great addon but suffers because you cannot change your browser user agent and also use this addon. Firefox users have an unskippable 5-10s delay before a video starts if youtube detects the user agent as matching firefox, so not being able to avoid this is a huge negative for this addon.

When it works, it's amazing. But on half of the videos, it just doesn't work. The UI buttons are gone, ctrl + wheel no longer changing the video playback speed - The only functioning thing is the custom theme color I set. Replicating this issue may have to do with "Place controls within the video player" but I'm not sure. Could be a conflict with another extension? If there is a way to fix this, I will change the review to 5 stars.

Sometimes it causes the video player to be very small (im on a 2560x1440 monitor), or sometimes the control bar just doesnt appear. If those were fixed, this would be 5 stars easily.

The disable autoplay feature doesn't work. All videos and playlists will play automatically either way.

I think we need a new update asap.

Will give it 5 stars when updated for Firefox.

In my "exodus from Chrome" I realy don't want to turn back to that hellhole just to not see shorts etc.

This extention is one of the better ones out there, but not up to date for Firefox (yet).
Let it happen, make it happen, make us happy and clean youtube-dwellers again :D

Dear Maxime,

Please update the extension for firefox. It's been so long. I recently learned that this extension is up-to-date on chrome with newer features.

bueno

стал исчезать на YouTube! исправте пожалуйста!

Good stuff, but when i'm using the vertical monitor, its not working good, when i trying to split screen for video player and other thing.

It stopped working. It was my favorite youtube extension but now youtube continuously pauses at random times, and no matter how much I restart it, it keeps happening!

Once the ad block was deleted, the only thing that this was useful for was to be able put a music video on repeat. Today that was deleted too. So I deleted this add on.

recently begins to forget to set full window videos. have to keep "rechecking" thebox.

It's great at increasing the video size... When it works. When it doesn't, there's no button to press that will make it realize it didn't work.

Sometimes it works and sometimes it doesn't. Not sure why. Does anyone know of a good alternative?
