So, not uBlock or whatever as everyone’s aware of that.
Mine (all Firefox):
Video Speed Controller. LOVE this one. A tiny widget appears on any video showing current speed and you hit a key to +10% / -10% (I have mine mapped to [ and ]). You can also hide the little widget (v) if you’re watching a movie etc.
Very handy for sites that don’t support changing video speed or have limited options.
Quick cookie manager - Allows you to delete all cookies on a page that you’ve visited. Very handy when “reject all” leaves you with like 20 cookies anyway.
Netflux - 1080p Netflix on Linux. Can be a little fiddly at times but it does work.
Have you set it up in the options menu? It’ll ask what you want to consent to and want you don’t want to consent to etc, then it’ll just do it’s thing from then.
I haven’t seen a cookie consent form in months, it’s great.
