Уважаемый Дмитрий, огромное Вам спасибо за всё

The dislike button's icon stopped showing a short while ago
Edit: Changed back to 5 stars based on dev response

Installing this, ironically, FIXED youtube for me. It was starting not to work properly, stalled out constantly seconds into videos, the whole tab freezing the whole browser, and now it's completely fixed and all I had to do was install this. Wacky!

I can now see how many dislikes a youtube video has

As of today 25.04.26 does not work, but worked well...

experienced glitch with dislike count, but good extension

It has experienced a glitch for me before, however is overall a really good extension.
