Under GDPR, you must opt-in. So blocking the popup is the same as no consent, if you're in the EU.
I don't trust random sites on the internet to follow the law anyway, so nuking your cookies and localstorage when you close the browser or navigate away is what you should be doing if you're concerned about this sort of thing. Obviously sites I need to stay logged into get on the allowlist.
same, I feel those cookie consent dialogs are solving the problem at the wrong level, remembering that in the end the cookies were always under your control. I think the gpdr opt in tracking requirements should have been interpreted as "the browser should not persist any tracking data past the end of the session unless the user gives explicit consent to do so"
luckily some kind soul her pointed me to the cookie autodelete extension. Which does just this. I am able to add the three sites I want to keep persistence as exceptions and just let everything else burn after a day. The fun part is how it trips the firefox "looks like you have not used firefox in a while" dialog every single time. I don't fix it because that is how I know it is working
