For everyone, this addon is still working via GreaseMonkey or other script manager and I suggest you migrate to that. For some reason, Firefox won't update this one. And yes, the button UI is fixed there. Thanks for the great work Dmitry!

tuff

i bin using this addon for years but now that youtube have removed the dislike button on shorts maby this can be a new feature to add it back in this addon ? :)

I give that 5 start cause it was doing its job for a long time. But we need an update urgent.

Amazing seeing all the dislikes, the dislike icon doesnt show but idrc. Overall, this is a very good addon :D

This extension saves a lot of time when searching for tutorials and guides. One glance at the like-to-dislike ratio is enough to understand if the method in the video actually works. The integration with the YouTube UI is seamless; the counter looks natively built-in. Highly recommend to every Firefox user!
