Use the extension/add-on "cookie auto-delete" https://addons.mozilla.org/en-US/firefox/addon/cookie-autodelete/

It's magic!

And "I don't care about cookies" https://addons.mozilla.org/en-US/firefox/addon/i-dont-care-about-cookies/

This clears those annoying GPDR things.

These two add-ons will change your life.

They are available for all the browsers, not just Firefox.

I feel welcomed.
