This is fantastic! The amount of customisation possible with just a few seconds to spare is phenomenal. Maxime seems to get the usability point of view bang on ! :D Kudos, to the developer.
The default themes could use a bit of work to make the UI a bit less jarring, but this is just nitpicking. Nothing a couple of seconds in a user-style override can't fix.

Overall, top notch addon to youtube on firefox !I say it this way, because you'd stop using youtube without this installed once you start. This is *that* good. :)

Adds a lot of missing options to youtube, like the pinned video.

Nice add-on apps

What yt should be

Gotta have it, gotta love it.

extension recomendada por buscador google....la considero genial porque puedo visualizar los videos sin cortes

It realy improve my way to watch videos.

I love the look of the interface and it's versatility. Keep up the good work! Thanks!

Very nice addon and very helpful, keep it up

I am extremely impressed with this addon. It is very well integrated to the point that I often forget this is a third party extension and that YT hasn't altered it's UI. I would give this a 5 star but I am too much of a perfectionist and am waiting for very minor improvements to be made before I jump to the full 5. Till then it is a 4.8/5.

Dear Dev, this is an amazing ext and I thank you for it.

Amazing plugin. Great functions, super useful.

The Enhancer does what Youtube should have done from the start to 'enhance' the user experience! Thank You!

Very versatile.

It works really well, the settings are clear and easy to use and the interface is intuitive. It doesn't interfere with anything else; no slowdowns of anything anywhere that I know of. I especially like cinema mode and thanks for bringing the new features to my attention.

excellent extension, the best ive used

Awesome experience.

Excellent!
