If you go to uBlock Origin’s settings and then select ‘Filter lists’, there’s a list maintained by EasyList and another by AdGuard that both block cookie notices. To my understanding, this isn’t enabled by default (at least it wasn’t when I installed uBO).
Apologies if this is common knowledge; I didn’t know about it until recently.
Why YSK: Cookie consent pop-ups are annoyances full of dark patterns designed to frustrate you into affirmatively opting into superfluous data collection and letting companies profit off your information. Saving just a few seconds on pages you browse adds up, and this is especially true if you use something like Cookie AutoDelete that makes your answers to these pop-ups transient.
Blocking accounts.google.com and facebook.com (you can unblock them on google/facebook if you actually use google/facebook) (in the “advanced mode” view that tells you what third party domains are on a page) gets rid of those, too!
(or maybe it was a different facebook domain, I dunno, we just block everything facebook on sight)
