Great add-on! Rated 5 out of 5 stars

This is a great add-on. It switches the youtube video quality reliably, even on embedded videos. But, in the current version it doesn't allow to switch to a higher resolution as set in the add-on's settings. Example: Add-on: 1080p -> set manual to 4k -> switches back to 1080p.

Great add-on. I finally replaced SmartVideo For YouTube, which hasn't been updated in forever. Though I do wish that this had a bandwidth saver option too :/

Broken with recent YouTube update Rated 5 out of 5 stars

Addon was working flawlessly but as of last week, is completely borked: just audio, video players seems to be shunted off to the left-hand size of the screen and won't render regardless of display size.

Broken for me v39.0 Rated 5 out of 5 stars

Love this add on. It no longer shows video though since 39.0 (addon version). I only hear audio. Running latest version of FF as well. The progress bar has been broken for a while too. The marker that shows how far you're into the video doesn't go the full length of video unless you're in fullscreen. Regardless, I just want video playback fixed please!

The no video playback started when youtube updated their player the other day.

Excellent--can't live without it. Rated 5 out of 5 stars

Love it. Every video loads at highest definition.
It also loads at your favorite size, say theater.

Autoplay? If you want. Playlist autoplay? Sure, can do. Suggested autoplay? Of course. Even Embedded vids can be set to autoplay.

Volume? Set it and never get blown away again in your headphones.
There's even a few more features, but all in all, give this about 10 minutes and you will wonder how you ever lived without it. 5 stars.

Номер 1 Rated 5 out of 5 stars

Сколько не перепробывал дополнений,это лучшее и по теме.
Большая часть дополнений-это всего лиш очередной цветной значок на панели,и лишний кеш. Считаю что разработчики YouTube High Definition - потрудились на славу.Благодаря этой проге мы не просто улучшаем просмотр видео,а реально еще то что какие функции введеш в понравившийся клип,то в таком качестве его и можеш скачать.

Time Saver Rated 5 out of 5 stars

I wish I knew about this add-on before! Up till now I've been manually starting youTube videos and then immediately increasing the resolution to maximum. With this add-on it happens automagically!

This is the one you want Rated 5 out of 5 stars

After trying dozens of addons for YouTube settings, I finally found this one. Other addons seem to have problems remembering or enforcing the settings you selected, or will only work with flash or HTML5 and not both. This one just works and works well. Install it, select the settings you want, then forget it's there.
