You convinced me, I’m totally adding this today! :)
I also would throw in sponsorblock to that too - it skips all the “but first, Raid Shadow Legends…” “don’t forget to like share and subscribe” nonsense :)
edit: thank you, I just poked into YouTube Revanced, and found DeArrow was on! This explains why I didn’t like youtube’s content when on my PC, so I’ll 100% be adding this to Firefox! :)
Thinking about it, I would not put it past me to have set it and forgotten 😂 it’s been a while since I played about with the settings!
