This is what I use ๐ https://addons.mozilla.org/en-US/firefox/addon/istilldontcareaboutcookies/
Firefox
A place to discuss the news and latest developments on the open-source browser Firefox
I second this but be sure to read it's description:
In most cases, the add-on just blocks or hides cookie related pop-ups. When it's needed for the website to work properly, it will automatically accept the cookie policy for you (sometimes it will accept all and sometimes only necessary cookie categories, depending on what's easier to do). It doesn't delete cookies.
Ghostery add on has also an option to auto reject cookie banners.
Use firefox new cookie banner feature (on nightly), or use uBlok Origin Easylist Cookie Notices and uBo annoyance filter, after that I never see any problem tbh.
Most site cookie consent disappear...
I'm not sure why but somehow AdGuard with the very same Annoyances list produces better results for me with cookie banners but AdGuard has other problems such as promoting its own services in the menu from time to time.
A good way to get rid of a large chunk of cookie banners is blocking cdn.cookielaw.org
and cdn.privacy-mgmt.com
in the hosts file. Lots of websites use either of the two services.
uBlock Origin. Also blocks a lot of those nasty ads .
