This is an excellent

One of the better (or best ones) ones on the add-ons "market", where are tons of similar...

Wonderful little add-on that adds a ton of useful tiny tweaks to YouTube, and can go even further than the minimal settings I have on. The toolbar is fully customizable and one is able to make it almost look like a built-in part of the site. One thing to suggest to the dev, adding support for the Firefox built-in PnP would be super useful, if only because the sizing appears to automatically scale a bit better than the presets.

A few days ago, I added this ad=on, and it was not showing up, like it did nothing, so I should not even be trying it again!? No sneaky underhand bull crap Eye am watching you! 😯
Now, just to be fair I have used this in the past and it did work fairly well, BUT!! DON'T LIKE HOW IT HAS TO CONSTANTLY BE CLICKED ON FOR VOLUME PER VIDEO AND SOMETIMES WITHIN THE SAME VIDEO TWEAK TWEAK! HINT HINT!

Does not remove ads automatically any more (offered button needs to be pushed). Otherwise great tool.

This is an excellent, must-have add-on if you ever watch YouTube. Make the YouTube page stop autoplaying videos, gives you the choice of several Dark themes, allows you to automatically stream videos in your desired quality (for example, low quality if you have limited internet speeds, or high quality if you prefer HD, etc. etc.). Great add-on

Die Erweiterung funktioniert prächtig! Mit ihrer Hilfe kann man jede Werbeanzeige überspringen / überspringen lassen.

Обновить надо. Тупит.

I've been a happy user of this extension for the past three years and always recommended it to make YouTube usable. Sadly, in recent months more and more things have broken. I know it's difficult to keep the extension up-to-date when the website it's used on changes frequently, but with no update in nine months, I can't keep rating it at 5 stars.
