Rated 1 out of 5 stars

Does not work!!!

Almost perfect! Not quite, but almost. Fantastic overall though! Rated 4 out of 5 stars

Does (almost) everything it says and works very well.

Only reason not 5 stars is becuase it does not work with embedded YouTube videos. Other than that... 5/5

Sweetness! Rated 5 out of 5 stars

Annotations good-bye!! HD here I come!
I feel like the master of Youtube with this little treasure. I'm no longer bothered by annotations nagging me, and I don't have to be bothered by clicking "HD" every time a video pops up. Also I have full volume control as well as playlist control- totally sweet. I felt like I had to make an account just to review all of the great add-ons and this one made the cut :)

This add-on is perfect!

It runs your favorite HD resolution every time without fail. You can kill annotations, and you can auto start videos!

On a side note... If you have FlashStopper add-on installed to stop those annoying videos you get all over the net that auto play, this will override that setting so you have just youtube vids auto loading!

Thank you so much for this wonderful, perfectly working add-on!

YTHD 35.3 running better than ever here on FF 35.01 Rated 5 out of 5 stars

I'm unable to speak about YTHD 35.3 new Firefox Electrolysis Support because I run only FF 35.01 where Electrolysis is not implemented, so all I can say is that it runs better than ever with this FF version.

Better indeed. Previously running a Youtube video in the same tab would break the full-page video layout (YTHD option) and this is no longer the case. YTHD moreover "follows" the numerous Youtube modifications (following here is more a run than a ballade) and this is a true pleasure for the user as opposed to add-ons which are seldom when not never updated. So thanks to the developer for this excellent work.

Mobile friendly Rated 5 out of 5 stars

Great extension Rated 5 out of 5 stars

Had it before but uninstalled it for some reason. I needed it again , as my internet is slow during the day and want to watch videos in 360p. However, there are some improvements and more features as I can see. Great job. Suggestion: A repeat feature would be nice for people that listen music or something.

A must have! Rated 5 out of 5 stars

I have been using this for about a year now. Such a great plugin! Thanks! Now I no longer have to click on the settings icon and set the resolution of every. video. I watch. Not sure why YouTube never implemented such an option. I assume to save bandwidth, though. Many Thanks!

Suggestion Rated 5 out of 5 stars

Please make an option to turn off the video (picture only). Still receive stream, just blacken the video or replace it with black image (customizable, maybe?)

Очень полезное дополнение экономит где то 30 сек. при каждом кликание на видео, не плохо было бы полностью русифицировать дополнение.
