Is there a (firefox) extension that auto-rejects everything on your behalf?
I have only seen auto-accept ones so far.
https://www.i-dont-care-about-cookies.eu/ says it'll reject where it won't break the web site. But it's called "I don't care" not "I never want" cookies :)
The extension is quite effective, but I decided to uninstall it after it got acquired by Avast[1].

Just in case you're not aware, a couple of options. It's possible (though who knows for how long) to add the filter list[1] used by IDCAC directly to uBO. The extension was forked[2] prior to acquisition if that is preferable. EasyList Cookie is available as a toggleable list on uBlock Origin, which hides many consent prompts - though only visually if I'm understanding correctly, so better to combine with an autodelete extension.
