For last few months started to notice that YouTube really sluggish, pages load slowly and every keyboard tap takes long time to register. It was driving me nuts and I blamed FireFox for becoming so slow. To my surprise the Enhancer was actually the root cause! 2 stars because resolution switcher and mouse volume control are very nifty. But this slowdown is unbearable to the point I had to disable this extension. I hope the author will take care of the performance issues.

So good and useful addon

This extension is the best. I don't want to miss it when using YouTube. All these possiblities to customize my experience are great.
Just one thing is a bit annoying: if i reload a YouTube-tab, this tab is "broken". I can't use the controls etc anymore. Only way to fix it for me is opening a new tab and navigate to the video (duplicating the tab or pasting the url into a new tab doesn't work)

The author missed one point, but what should users of the Firefox ESR versions do?
How do I upgrade?
I have the latest version of Firefox ESR. And now what to wait until the version reaches "121.0"…

Автор упустил один момент, а что делать пользователям версий «Firefox ESR»?
Как обновится?
У меня последняя версия Firefox ESR. И что теперь ждать пока версия не дойдёт до «121.0»…

omg, so lost w/o this. tysm One of the first extensions i always get when getting FireFox for the first time. I have to say after trying them all this YouTube extension is hands down my favorite.

Would be perfect except it now tends to break any Youtube video that is age restricted or has a violent content warning. Clicking the "I understand and wish to proceed" button just makes the initial warning pop up again and the video is unplayable. This mod is the cause of this issue since disabling the mod made the video play just fine.

Adblock is removed. Did Google buy them off orrrr?

Essa é a melhor extensão para o Youtube!
Uso há muitos e muitos anos.
A função eu mais gosto é a de usar o volume segurando o botão direito + scroll.

Used to use it a lot to skip ads, but now that feature is gone. Other than that everything is great

Glad to see this addon is back. One bug though is if you convert shorts that preference works but it won’t let you backspace to the main page, it just keeps staying on the short’s video page. Or sometimes it will backspace to the unconverted video.

While the extra control functions are nice, it has caused the videos to freeze up constantly. As a result, I have had to stop using it.

Return of the King!

To everyone complaining about adblock, just use μBlock Origin smh. You may not have experienced any problems but a lot more people have.

I wonder why there's a min version of 121 though, why wouldn't 115 work?

起動しないので使えない

After a lengthy absence, It is back, and I must say, this addon is unparalleled in its excellence. It has surpassed all others I've encountered, which attempt to mimic only a fraction of its functionality

One of the best, excellent work

This is my go to extension for keeping my youtube videos at 2x speed. Though I have noticed with youtube's API changes that the extension doesn't always work. Either a new window or reload of my browser is needed to get it to work.

Edit 2024/7/14: The extension works really well still but doesn't always seem to run when loading up youtube. Sometimes I need to reload the browser to get the extension features to work

2024/9/26: The issues listed above have gotten worse where the extension doesn't appear to be active as I will have no preset settings working. Unable to narrow down the cause as some tabs it works others it doesn't. A new browser session doesn't seem to effect it

2024/11/16: I no longer get any features of this extension working.
