Works great now. Recent updated fixed the issue with part of the controls missing.

THANK YOU so much for this extension! I was horrified to go onto YouTube today and see an eye-hurting, unwatchable mess. What on earth were they thinking? This add-on makes it look more like before. Wish I could give it 10 stars!

Returned old youtube layout and got rid of new garbage one. All I wanted from this addon

I just woke up to an awful design decision by YouTube to put recommended videos BELOW and comments to the right... this extension (perhaps accidentally?) reverts this change, though the recommended thumbnails are quite large.

Downloaded the extension and ever since dozens of videos I haven't seen begin showing up under my "liked" category. Extension seems to be using my account to sell likes to youtubers in the background.

Amazing extension. Highly recommended!

amazing

There's just so much respect to be given to a random person on the Internet who just does the right thing and you are definetly one of them. Thank you so much for the possibility of using your App.

Works great, I do have an issue when using multiple YouTube tabs, only the first YouTube tab loaded has the Enhancer activate, the others don't get any of the benefits of it.

Love the extension, does a lot of stuff that enhances my YouTube experience. So thanks for whatever led to that point.
Here comes the "But - instead of shying away people blatantly that are coming to your website with this:

"To get in touch with me send your message directly to webmaster@mrfdev.com and if you're lucky you'll get a reply.
Don't send feature requests, I ain't got time to implement new features."

These people are trying to help you with ideas of new features, which will make your work even more renowned. So turn the approach around. Give the possibility to donate 5 bucks and by that give me the chance for a submission. Nipping ideas in the bud is the wrong mindset.

Great enhancement suite for youtube, but please keep the users for Firefox forks in mind and make it so it can be used in FF ESR based forks for longer :)

Amazing, makes the experience with YouTube much better. Especially the shortcuts.
