Just works, and the most recent update added an aesthetically pleasing UI enhancement that's really easy to personalize. There's a good reason it's on Firefox's Recommended list.

The recent update was awful, too much buttons screen, you don't care about UX, do you? it's really on my nerve
those buttons are not that useful, make a option so we can disable it or I have to use something else
OR is there any option to use older version ?

This last update hides the volume bar in all but fullscreen mode in favour of some buttons I'm certain are ignored by the majority of users.

The length of the video and length remaining is also blocked by these new unnecessary buttons.

I'll be turning it off I guess. I can't remember benefits it came with so they're not important. I'll take easy access to the volume slider and ability to see the length at a glance over whatever features I seem to never use since I can't even remember what they were.

Ich hoffe das die Dislike Funktion die genutzt wird ja auch bei dem Projekt mithilft und man nicht noch das Extra Tool runterladen muss damit das stimmt am Ende. Zudem hat es viele andere gute Features aber auch so einen oder andere Schwächen. Die Leiste z.b. im Player Bereich macht mit ublock dann gerne probleme und man kann so nicht sagen skippe die Werbung wenn diese nicht Skippbar ist.

Disappointing update

Been absolutely smashing it with this recent update! This extension in general is a severe improvement of my youtube experience. I could probably not live without this extension anymore. Just donated as well!

While I do like that the buttons now match the player's buttons in this new update, it feels like an extreme case of feature creep. Too many buttons on the player makes it feel overwhelming, and it keeps switching on autoplay whenever I try to turn it off.

I've been using this for a looong time and I really love this a lot. When i listen to music my volume is low but with this i can force it to be louder and its helpful. With the new looks and customization, I feel like I have even more control. My favorite look is the Ubuntu Purple and the others are very well done too, lot's of options to choose from and given the option to make our own theme is awesomeee. Great Job!
Edit: I just noticed the video filters, I love the idea of it a lot because that could help out a lot of people with vision problems and so on.- thanksss

This "enhancer" makes the options confusing, I can barely adjust volume of the video and every darn time I open a video in a new tab, Autoplay is automatically on. It's seriously annoying.

Love the new update, can pick the good part of the song to listen to without all of the rest.

Everything works, but it won't load when I start Firefox. I have to go into Add-ons manager and toggle it off then back on for it to work. Very annoying and will have to look for an alternative add-on and uninstall this if it isn't fixed. What's the point of the Add-on if it won't work!

Great add-on. Only thing annoying me with the new update is the Auto-play feature is constantly being reactivated.

incredible and usefull work thankyou!
