Sorry for the harsh review but this addon has a HUGE issue that hasn't been fixed in a year.
Every now and then, randomly, this addon will stop working. The advanced control features will go away permanently.
Literally the only way to fix it is to reset all cache & cookies. Other reviews bring this up too, it's not just my machine.

This is very infuriating. On one hand, the features of this addon are incredibly useful, and it's annoying to use Youtube without it.
On the other hand, I don't want to keep losing ALL my website logins & settings just to keep it working. I didn't want to write this review but after a year I don't think this is ever going to be fixed.

Generally a good extention, but seems like the playlist reversal feature does not work currently. the button is enabled in the settings but does not appear anywhere in the UI at all.

Works super well! especially the speed option, even if it's a little fiddly with a trackpad.

Impressive level of control over YouTube. My favorite feature is forcing it to a specific resolution. YouTube lately has been quietly downshifting your video resolutions by default to save themselves bandwidth.

4/5 stars because this doesn't include a feature (That I have found) for quick and easy YouTube downloads. Would be an awesome feature to add.

Please keep support for Firefox ESR version.

swear to god you used to be able to download with this thing but they probably got sued or something and now its useless for me

He is amazing, help-me a lot putting out all noise images and screens that does not matter to me. That's it.

Very handy extension and less sketchy than Magic Actions IMO. There is one long-standing bug that is annoying though -- if you have automatically expand player and use available space based on window size enabled, when you open a video in a new tab that function doesn't work. It just uses the default YouTube theater view. Going into miniplayer and back fixes it but it's annoying. Otherwise no big complaints.

I am very sad that Firefox's policy had discouraged the creator of this extension. Hence, we, firefox users, have to use version 2.0 instead of enhancer version 3.0 that are currently available to edge and chrome.

Due to this reason, the reserve playlist button is bugged and can not be displayed on enhancer's control bar. Such a useful tool ended up not being able to be utilised.

It is a phenomenal and incredibly useful extension.

Nie jest taki zły,pozwala trochę dostosować na własny sposób które klawisze się przydadzą,ALE od około tygodnia i dłużej nie mam dostępnego automatycznego rozwijania opisu filmów,oraz w moim przypadku opcja ,,nie zapobiegania auto-odtwarzaniu dla list odtwarzania nie działa gdy korzystam z publicznych list np. z muzyką,w prywatnej liście działa nawet bez tego dodatku.
Osobiście bym się cieszył gdyby ta opcja tyczyła się ,,wszystkich" list odtwarzania,i auto rozwijanie opisu gdyby wróciło.

Works great! No complaints here
