After choosing my settings in the enhancer for YouTube it worked perfectly instantly. Will continue to use and recommend.

大変いいです

I am surprised at what this add-on can do. No other browser has thought about this facility

Excelente extensión. Se ha convertido en una de esas extensiones que debes tener>
¡Buen trabajo!

Awesome

Very happy to see this extension on Firefox, works just as great as on Chrome!

Absolute fantastic multifeatured enhancer. All what youtube's google couldn't or wouldn't think of

Awesome features and finally I don't bleed from my eyes when browsing youtube in the dark

One of the best addons ever made.

Great Plugin to get the best experience in watching youtube content.

One more suggestion if there is any way to hide/autohide the youtube topbar(search)

No ads, every customization you'd like to see on YouTube, this takes care of it.
Absolutely love it. Hope the video alignment issue gets fixed soon (video frame is beyond the screen and 1/3rd of the video is cut off, have to turn on + off theatre mode or fullscreen to fix it)
