when you deny ‘all cookies’ and add exceptions for the few you need to, the cookie banner keeps splashing even if the sites’ cookies won’t be accepted. Consent-o-matic gets rid of them and it refuses automatically for the sites that won’t work without “essential” cookies. (In Europe there are organizations that verify if these choices are respected)

this way you don’t need cookie auto delete

i use uBlock myself, with very rigid preferences but people find uBlock complicated 🤷 so i install this addOn with a cookie shortcut for the sites they need to accept cookies

i add a weak ublock that won’t get in their way though, for all the trackers &c
