Excellent extension so far, I've had it for several days, however it looks like YouTube made some kind of change to their API, as the extension doesn't seem to be working right now.

Edit: Looks like it's fixed :D

why did youtube have to remove dislikes

Youtube is dumb.

More people need to get on board this, to improve it's effectiveness! Show Youtube how horrendous it was to remove dislikes!

Much respect & appreciation to the creator for putting so much of his own time & effort into this vital tool!

thank you

Thank you for this!
It would also be great if this extension was enabled for Firefox Android.
