The more buttons and sliders, the better. Enhancer for YouTube has more adjustments than I've had a chance to try yet.

One of the adjustments -- "Filters" -- is not concisely named. It has a dozen controls to fix the video image, but I was looking for audio adjustments.

For a long time, I avoided youtube as a music provider, simply because my Winamp media player has an equalizer and youtube doesn't. Also, it's been many computers since I had one with an equalizer that would affect flash players and youtube. But lately, it became undeniable to me that you can find any music you want on youtube < :) happy notes :) >. I'm bluetoothing from the laptop to my hifi stereo across the room -- it has tone controls, but I don't want to get off the couch. I wish Enhancer for YouTube had a nice 5 band equalizer, which would be plenty appreciated. That would necessitate changing the name "Filters" to "Video," and introducing a section of controls named "Audio."

I do find the "Audio Boost" button very useful; I'd like to see an indicator to show whether it's active or not.

The best extension for Firefox. You can change the speed of the video for any value you want, like 0.9 1.2 1.3 and even beyond the limit, going to 2.2 2.5
That's my favorite feature.

I simply would not be using Youtube at all without this App. Tanks guys

Fantastic extension that automates so many settings and makes my YouTube Premium experience even more premium. Be it actively watching videos or playing music in the background while working or driving, I cannot imagine getting a good experience without this addon. Thanks to the kind folks behind it. Yes, there may be some bugs but this add-on deserves 5 stars.
