Works very well over all
Sometimes I have seen some odd behavior but Google CONSTANTLY changes Youtube code so you can't fault developer for that.
Tons of functionality controlled by many settings
Thanks for all the hard work

it's great, the only reason i'm giving it 4 stars is because it doesn't work with 360° videos

goodjob

Addon is not bad. Just a couple of things I'd like to see changed.
1) On a mac when you two finger scroll (which is the equivalent of mouse wheel scroll) to adjust the volume when using the "natural" scroll direction, scrolling down increases volume while scrolling up decreases volume. Just have a setting that reverses the scrolling direction, maybe have it say something like "use natural scroll direction" under the setting for adjusting volume of youtube videos with scroll wheel.
2) Really all I wanted was an addon that auto-pauses videos when I go to another tab while the video is playing. Firefox already auto-pauses youtube videos that are loaded in a background tab. That's not a big deal. The big deal is auto-pausing a video that is already playing in an active tab when you go to another tab. Is it even possible to do? Thanks.

Awesome.

Крутое расширение...

Думал получше будет работать

Excellent!

If it just have the ability to take clean screenshots of the video, then it would be perfect.

Useful tool!!

Works EXCELLENT 10-4

As if it was even possible...they've gone and figured out how to improve your Utube experience! Using the Enhancer add-on is easy to do and by being able to customize your settings or restore it the defaults (should you get too excited and get carried away, lol) means you aren't pausing video's and playing with the "quality" settings every time you decide to move to a different "channel". Just one click and...all better. Now if someone could share the secret of how to "flip the mirror" with me (as some uploads do play as if you're watching the reflection in a mirror?!?) oorrr how to maximize the screenspace when someone's created a border that's constantly moving (very distracting for those of us with ADHD) I'd give ya's 5 bright & shiny stars...until that day 4(+1/2) is about the most I ever give because total perfection is scary so I don't go there!! Definitely NOT sorry I came across this add-on!

Why aren't you working for Google? I hate the "new" Youtube look and feel, this is sooooo much better. The Deep Dark (KDE) is fantastic and the "resize player" works and looks great. Thank you.

Perfect! really enhances your youtube experience.

Me fascina éste complemento, mejora a Youtube y es fácil de usar, lo recomiendo.

Muy practica y cómoda. Recomendable.
