Adding on to this, while this article is fast approaching 20 years old, it gets into the quagmire that is web standards and how ~10 (now ~30) years of untrained amateurs (and/or professionals) doing their own interpretations of what the web standards mean–plus another decade or so before that in which there were no standards–has led to a situation of browsers needing to gracefully handle millions of contradictory instructions coming from different authors’ web sites.
Here’s a bonus: the W3C standards page. Try scrolling down it.
Uhhhhhh, bem vindo a EasyList/uBO – Cookie Notices.
Sorry, can’t speak Portuguese beyond the stuff out the front of Nando’s. uBlock Origin includes two lists in the settings (both off by default) that also handle bypassing cookie notices. The other one is AdGuard/uBO – Cookie Notices, but I’ve been getting by with just the first one enabled. Useful if you want to keep your number of extensions down.
EDIT: Also just realizing this is not Portuguese. Told you I can’t speak it.
