I'm very happy with Consent-O-Matic for auto accepting cookie popups with privacy preserving choices done for me. Prior to that I used "i don't care about cookies".

On uBlock Origin, the list "Easylist/uBO Cookie Notices" and the Annoyances lists help remove a ton of those cookie popups.

Why autoaccept?

[Karunamon]

Because rejecting all tends to break things or make them work non-optimally, and practically speaking there are no negative consequences from accepting, so even the mental overhead of thinking about what to do with the dialogue is a waste of time. If you do really, truly, care that much then you would be better served by accepting everything and then simply throwing them out when some time has passed or the tab has been closed.

I meant "accept" as in OK'ing the dialog, which it does with the most restrictive options by default. So, autoreject if you wish.
