YouTube’s ad blocker crackdown now includes third-party apps

Wish I could say the same.

I'm also using firefox + ublock, but Ive noticed when I'm watching shorts, I'll occasionally get an ad that's disguised as a short. There's no like/dislike buttons or anything.

Sometimes I have to reload the page when using these 2. the page will load but just have a youtube icon in the centre of the player or the spinny circle until i hit f5

Yup same here, on android
