it worked like a charm now after following quick fix guide from Firefox user 12256057, thank you my dude, you're the real MVP!

also edit:
thanks to the developer (Dmitry Selivanov) for the update 🙏

YouTube feels empty without it. How can you have likes without dislikes? It's like Ying and Yang.

Super responsive dev. When YouTube breaks the extension, he even uploads fixes to GitHub before they get approved by Mozilla. Keeps everyone updated on his Discord.

Works great, waiting on fix

Dev quick to respond when YT updates cause issues with extension not working. Happy to see it. Been using this for awhile now and just realized how much I missed it. Thank you Dmitry!

Thanks, great extension.

Not working anymore

Doesn't work now.

At least this is a website where we can still rate things

實用

Thanks to this Extenstion we can still differentiate between good and bad content. Really sad that YouTube decided to remove this essential feature.
