EDIT: I didn't realize the anger this would bring out of people. It was supposed to be a funny meme based on recent real-life situations I've encountered, not an attack on the EU.
I appreciate the effort of the EU cookie laws. The practice of them just doesn't live up to the theory of the law. Shady companies are always going to find a way to be shady.
Well, you can install both of these add-ons via this workaround: https://blog.mozilla.org/addons/2020/09/29/expanded-extension-support-in-firefox-for-android-nightly/
(I have used both. Both work. Although, again, I'd rather recommend I Still Don't Care About Cookies + Cookie Auto-Delete.)
However, Mozilla plans to make much more extensions available for Android soon, so you might see these regularly available before the end of the year. This is what we know for now: https://blog.mozilla.org/addons/2023/08/10/prepare-your-firefox-desktop-extension-for-the-upcoming-android-release/
