This and "Youtube Watchmarker" are the best Plugins for YouTube!

Used to be a no-brainer add-on, but currently is a huge performance hog that will constantly freeze youtube tabs, so there's a trade-off to make between the great features it offers and having the speed of using youtube in Firefox roughly cut in half.

Update: Turns out the slowness was/is actually a bug with Firefox 86 and later on Windows 8.1 and only affects exactly one computer of mine. It's still a no-brainer add-on.

Everything is great !

Best youtube application out there, amazing stuff

If you spend any time on youtube, you need that add-on.

Yeah what others have said - these latest updates (I'm using 2.0.103.2) when proceeding through a playlist, the first video plays at the preferred resolution, but the "next" video in the list doesn't. I presume it's a bug, hopefully it can get fixed soon?

I think the last update is alright design-wise. The problem I have with it is that it's BUGGY. Auto-expand does not work correctly anymore and it's very annoying to have to enable it manually each time. Also the import settings feature does not work correctly between old and new version.

Good thing the version history exists, because until all the problems mentioned by other users get resolved, I'll keep using the old ones.

The latest review that made the buttons collapse when not in use is useful but there is something else updated that prevents videos from automatically expanding to the viewport which was fixed before this update. Please revert that setting. It was only fixed in the previous update after so long and now its having the same issue again.

Excelent work, keep it up!

I've used enhancer for youtube for some time and it is irreplaceable. I would not be able to watch youtube without it!
