Add-on doesn't work properly after new YouTube update Rated 3 out of 5 stars

Nice add-on, but after YouTube's recent update, it became bugged and needs a fix.

I have the add-on set to enlarge the video to Theater Mode whenever I start a new YouTube video, but it refuses to work properly.

It only enlarges the black border around the video, leaving the video itself stuck to the left of the screen in default mode. This means I must click the Theater Mode button on the video itself to have it displayed properly, which is counterproductive and highly annoying.

Fix this addon Rated 1 out of 5 stars

Quit deleting the negative reviews Mozilla. We have a right to the freedom of speech. I have problems where YouTube videos don't go HD and you don't fix it? Fix it now.

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.

Rated 5 out of 5 stars

Addon works flawlessly, good job, well done!

Interesting stuff! Rated 5 out of 5 stars

I just love this add on. Both user experience and quality have tremendously improved. Thanks for the updated version!

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.

Soaping playback video Rated 4 out of 5 stars

Заметно снизилось качество воспроизведения видео (отсутствие четкости, замыливание) по сравнению с версией 38.4, но лучше, чем - 38,5, 38,6.
Пожалуйста, обратите внимание на данный отзыв, так как Ваше дополнение лучшее в своем классе и должно приблизиться к совершенству во всем :)
---------------------
Markedly reduced quality video playback (lack of clarity, blurry) compared to version 38.4, but better than - 38.5, 38.6.
Please pay attention to the review, as the addition of your best-in-class and should be closer to excellence in everything :)

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.
