Lot's of great options, but it causes at least 1 in 5 videos to crash and requires a reload to the youtube video page.

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.

Not bad. Came over from Iridium after developer blew it up and started from scratch but is a long way off from what it did before he started over.

That said, Enhancer is okay does a lot of what I'm looking for like remove ads, resize video beyond what YT lets us, etc. But it also lacks some of the things I'm looking for like hide comments, that "Toolbar" can't be moved, remove the "up next" and "related" videos.

Overall a 3/5 stars

Works nicely. Recently has started refreshing every page if dark theme enabled though. Also has ads in settings for some 10 year old Android racing game...

It seems there is no way to disable the annoying youtube floating vid if its been playing on another page.

Would be higher, but with it installed all youtube videos freeze at 2 min unless you manually scrub.

I've been using this add-on for a while and it's great.
However today I noticed that the layout of youtube had changed and it was no longer in dark mode, and the option to enable dark mode was also missing.
It seems that this add-on has caused this because as soon as I diabled it I got the new layout with dark mode again.
