Fantastic addon but won't install on latest Waterfox as of about three days ago. I can't figure out why, I've even changed useragent to latest FF and it won't let it install. The support site appears to have been closed for a couple years now :(

Je suis un peu déçu, car il manque une fonction bien utile qui permet d'activé la traduction des sous-titres lorsqu'elle ne sont pas dans la langue par défaut du navigateur

The addon does what it claims, however, at some point it started to have a huge problem - it only works once. If a load the YT page, and then it dets discarded, on subsequent view the addon never activates on it, no matter what I do. I can reload the page or even de-activate and re-activate the addon - it doesn't help, it won't load on the same address ever again.

Also tried rolling back to a much earlier version - while this problem seems to not happen as much, then addon stops blocking ads, which is an equally bad problem...

The queue has been behaving strangely lately.

I'll give it five stars when it'll show thumbs down.

Veamos pues...

Sometimes arrow keys are for backward/forward and sometimes they are for volume. So confusing.

Had been enjoying this for quite a while. Lately videos appear to re-load after a few seconds of play, and the speed change is no longer applied.

Keep controls visible without having to click the ••• control or hover over it with the mouse cursor, this feature doesn't work.

It's a good idea but I don't really want to read all this features. Therefore I recommande you to make it more designed and intuitive (you interface). Sorry & Thanks you

unfortunately cannot recommend it, it's a great addon, but each update breaks something basic and you gotta wait a certain period of time 'till they fix it, they will... eventually, but it's still pain in the ass so it might even be easier just use default youtube, cuz that's pain as well however, at least you can count on basic features to work every time you watch something and you don't have to wonder wtf is going on so if you use this and something doesn't work, blame this addon probably

Useful add-on but one of my favourite features recently stopped working. The app no longer brings the dislike numbers back. This app has not been updated for 5 months so I guess Youtube code has changed since then. I am hoping for an update to this app soon that will again bring the dislile count back.

This extension was flawless at suppressing ads, while keeping ads visible for subscribed channels. Hard to understand why such a great feature suddenly gets removed. As such, this extension is no longer useful to me.

Good, but unfortunately does not block adds as once did.

The default speed setting stopped working. You have to set it manually for each video.

Disable AutoPlay does not work without restarting browser. Volume Booster breaks when using privacy preferences. I contacted the developer, but they refuse to disclose what settings they are utilizing. There may be privacy issues.

Been an absolute must have in my browser since I discovered it, however like others have said, the scroll wheel volume control has been broken, working on/off since last update.
And causes videos to load slower, sometimes even buffering for 10 seconds before the video finally plays, sometimes it will load indefinitely.
Seems the addon has a problem hooking to the page, sometimes it will not have any function at all.

In the latest versions a customization option was removed... please add it again!

The option allowed you to change the aspect of the bar when it is at the bottom of the screen. It becomes meaningfully useful when there is a combination of theme/settings that makes toggled and untoggled buttons look the same.
