I have not used it yet so if all goes well it will change to a 5 star.

My Windows 7 PC broke so I installed Win10 on a new PC - and found out that I can't activate the classic version in YouTube anymore.
So I copied over my "C:\Users\Name\AppData\Roaming\Mozilla"-Folder from my old PC to the new one and this method restored the classic YouTube View - so I could use this Addon again.

=> If you can*t activate the classic YouTube version find an old "AppData\Roaming\Mozilla"-Folder and replace it with yours. Be advised that this folder also stores all website passwords!

I think YouTube got rid of it's classic version. There is no option in the drop down box to switch anymore, therefore I think this is outdated for good. Thanks for YouTube Plus, it has changed my experience dramatically!

Great add-on. If only Youtube was this flexible out of the box. A must have if you frequent YT!

A wonderful addon!

I don't know how I ever used YouTube without this.

It takes some customization, but it's worth it.

100% compatible y full rendimiento

A lot of features that work very well. I love the pop-out viewer and the ability to hide almost anything. The auto video page for channels is a must. Thank You!
