скриншоты не работают
минусов у новой версии больше чем у предыдущей !!

Everything works, but it won't load when I start Firefox. I have to go into Add-ons manager and toggle it off then back on for it to work. Very annoying and will have to look for an alternative add-on and uninstall this if it isn't fixed. What's the point of the Add-on if it won't work!

This used to be a great addon, latest update is still functional but the new interface is awful, too fussy and intrusive. Bring back the old look.
Edit - for those who prefer the old look you can rollback to the previous version

I don't like the new update. New buttons are way too big and cluttered. The 'boost volume' button covers up my sound bar for some reason. The speed button was turned into three separate buttons, you can still change the speed by scrolling the main one, so I don't see the point of other two. Also before the update you could scroll down and still use the toolbar but now you have to go all the way up.

The missing minibar at the bottom of the page is frustrating because all the buttons are now stacked on the youtube player making it ugly and unnecessarily full

Speed of the video can no longer be controlled. And no I did not use boost sound.

This extension has a plethora of options, but they're not well organized. (Look at the settings for any popular IDE for how it should look.) What I needed was A) an assurance that the default settings would not modify YouTube at all (or at least a summary of the default changes), and B) a quick way to discover if the specific feature I need actually exists in this plugin.

Without A), I have to read and understand *every* option before I can rely on this plugin, and without B) I don't even know if it's worth the effort or not. In summary, the new-user experience suffers from the sheer magnitude of what it can do.

I find this to be highly inconsistent. Sometimes the videos are in expanded view, sometimes in default view, sometimes in cinema view and sometimes in theater view, all without changing the settings in this extension. Makes it highly unpredictable as to what my viewing experience will be.

On top of that, the settings are very obtuse in what they actually do and how thee interact with each other. For example, I count at least three different settings for the viewport size. WHY???

Decent when it works properly but that is rare. 90% of the time it doesn't turn off annotations despite being set to and an increasingly more annoying issue is videos loading in a lower resolution forcing me to reload the page for the set resolution to take effect. The extension seemed to work much better with the legacy version of youtube. Since that's been completely scrapped now this extension is becoming more and more inconsistent. Dropped my new rating to 2 stars from the 4 I gave in the past because the issue with annotations has still not been fixed despite almost 3 years having passed.

Unreliable performance. As often as not it does not run when I select a video. Also, the buttons for screen size adjustment vanish for no reason.

Conflicts with LastPass, hangs out when i click skip ads.

Does not allow any fraction play-back rate (I am trying to sync a recording with a slowed down YT video)

neat settings and capabilities, but it's unusable because it makes firefox crash during every video. nice try though

Not getting activated. I'm Using Firefox in Linux Mint 20 Cinnamon.

Firefox version: 80.0 (64-bit)

"disable auto-play" feature does nothing

Always on top option not working

The features are great, but pause autoplay doesn't work.

Очень классное расширение. Куча полезных и приятных функций. Очень доволен им, был, до последнего обновления. Постоянно выскакивает ошибка воспроизведения, вылетает браузер и просто оно перестаёт работать. В итоге, ищу альтернативу, чего делать не хотелось.

Be advised, Youtube is stuttering and lagging with this extension for now.

Hay montones de complementos para el youtube y son todos iguales, y ninguno tiene lo que me interesa que es la opción de poder ver los vídeos de las listas de Youtube en orden cronológico.
