hi guys! this is NOT UPDATED since 2016 so a lot wont work.. Try Improvedtube.com tho ( ​https://github.com/code4charity/YouTube-Extension/blob/master/README.md ).
, it is the only big Youtube extension developed openly and since several years and Recommended By Firefox🦊 (the alternatives resigned along the way, because it requires continuous work)

Does not work. Clicking anywhere does nothing.

wszystko działa dobrze
everything works well

No sirve

Doesn’t work at all.

Not a good player

This ad on has no purpose!

I installed this in waterfox and when I attempted to change the color, I could highlight the the text in the textbox but could not edit the color. This makes the extension useless for those that want to change the theme and actually be able to see data that is blacked out.

An extension that does not do as the author claims is a pointless extension.

Muito bom e útil
