The extension accepts essentials only when that doesn't break something and when it's easy enough to do it. Regarding Google, it worked like that in the past. Too many people complained that it takes too long to accept only essentials on the redirected page so I had to give up.

It used to (and still could) work in regular Firefox for Android but Mozilla team decided to stop supporting all extensions (they now allow only a couple of handpicked extensions).

It works in "Firefox Nightly" though, but the installation procedure is a bit complicated. I tried it and it works well: https://blog.mozilla.org/addons/2020/09/29/expanded-extension-support-in-firefox-for-android-nightly/

It also works in some other Android browsers.

It rejects cookies (or just hides the pop-up) whenever it's easy enough to do it and if that doesn't break the website, otherwise it accepts some and in some cases all cookie categories.
