This is a great add-on for firefox. However there are features that can be added and I can't believe they haven't been added years ago. For example, I need an option to check if closed captions are enabled and disable them. Often times I use youtube without being logged in and closed captions are on by default. It's so annoying. Right now I can do this by using a script I found on some website. Also an option to organize comments by number of replies and number of likes would be nice. There is only 1 option to organize comments. Newest to oldest. More options to organize comments would be great. Thanks.

La plupart des problèmes que j'ai avec youtube depuis des mois provenait de cette extension et de ses paramètres par défauts qui changent sans cesse.
Je l'ai désinstallée, ma vie est redevenue plus belle.

A great app, some problems, not sure where to send the info, so ...`here` i guess, `stop autoplay` has a pretty spotty reliability, sometimes it stops them, often though, it doesnt, the youtube uploader has set auto play orsomething (maybe its youtube that does it, or recommends it ... ?), whatever the cause, `stop auto play` is usually non-functional. Overall, a great app, again, finding where to report a problem led me to here, so ..here it is. Be good :)

Не изменяется цвет полосы просмотра видео, стал всегда красный.

the youtube logo doesn't change color

Toolbar doesn't load 99% of the time, but when it does it works great. Make the Toolbar always show up like I assume it is supposed to and its 5 stars.

Perfect! Thank you a lot for developing this useful add-on!

再生画質の固定や指定時間ループ再生など細かな設定が出来る気の利いた拡張機能。
動画のミラー反転機能はあるが、90度回転機能も欲しい。それだけが非常に惜しい。
