There is a way to enable arbitrary add-ons to work on Firefox for Android, but you have to do a few extra steps: register a Firefox account, create a collection of extensions, then add that collection to your phone. I can tell you that Conset-o-Matic definitely works if you take this route.
ublock origin has inbuilt filters you can turn on for cookie popups that work for almost every site I've been to I almost never see them anymore ublock origin is just all around great
Well to be honest, even if each and every website wouldnt use dar patterns and there is a clear choice to refuse with one click, it would still be obnoxious to decline everytime you visit a site.
I've been using this addon for some time, but I think the best way to get all of yours would be to use uBlock lists and then whitelist sites as needed when things break
I don't really have anything specific for cookies, just doing the basics with uBlock + Firefox + Firefox containers. I do keep my facebook/instagram/other problem-logins in separate containers, but that's about it. I saved this thread in case someone else has other suggestions :)
