For me, this is the best YouTube addon available on Mozilla. I'm very happy that it received an update that fixes bugs related to the new YouTube UI. It took so long I even started looking for a replacement addon. Happily I'm here again.

The best add-on for YouTube is back on Firefox ! Thank you :D

If this add-on stopped working I might actually stop using youtube, which is why I was so glad to see the recent update.

However, the update also introduced a number of bugs. Default playback speed doesn't work. In full screen the UI scrolls but the video doesn't. And there are too many issues on live streams to even list here.

Is there a better place to send detailed bug reports?

5 stars because when it works its fantastic, the bugs dont actually bother me too much, and the ongoing development gives me hope.

Ever since the latest update, when trying to scroll on the speed adjuster icon the entire screen scrolls, when previous the screen would lock. This makes adjusting the speed, especially when scrolling down, very difficult

I would like to thank the author for returning to the development of the FireFox add-on. Thank you very much!

I don't know why, but Enhancer works on some YouTube tabs, and doesn't work on others (it usually doesn't work if I open the video in a new tab). I don't know the reason. Regards.

Incredible work. Thank you for all that you do. The recent update darkens the screen to the opacity % in the cinema settings when going from cinema mode to fullscreen. Currently troubleshooting but haven't been able to figure it out.

Did we finally get an update?

Great! But it seems can't work in firefox nightly

Great extension, but it stopped working for me about a week ago. Recent update didn't help and previous versions don't work aswell. I hope it gets fixed for me in the next update somehow

This is the best firefox extension ever!!

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.

A great suite of QoL features YouTube should already have! I especially like adjusting video volume with the mouse scroll wheel and watching the video inside a picture-in-picture viewer while scrolling comments

Thanks for the update!

Its nice to see that its back and updated , But the new version broke cinema mode , when going full screen it dims the player the same amount as the setting is and make it not intractable when cinema mode is on. I got it set to 98% so its completely unwatchable in full screen with cinema mode on. Even reinstalled and it did not help.
Edit: fix worked.

The update landing page claimed something along the lines of “tons of bug fixes and improvements - too many to list.”

In reality, I don’t see any improvements at all. In fact, it broke features that were working perfectly fine in the previous version.

For starters, embed quality stopped working for me after the update. I’m not sure what else is broken yet, but I’ll update this review as I encounter more issues.

What makes this especially disappointing is that I previously found the extension very impressive. The old version worked flawlessly for me, even after YouTube’s UI changes. Every feature I used continued to work without issues right up until this update.

Given this experience, I’m honestly starting to wonder whether the original author is still maintaining the project, especially considering there’s no proper changelog and the overall experience has clearly regressed.

Anyway, just a heads-up to others. Someone should confirm whether this update actually comes from the original author and possibly decompile the code to check for anything sketchy. I’ll most likely downgrade to the older version and disable auto-updates.
