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

On Android it works in browsers that fully support extensions, and it also works in "Firefox Nightly", 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/
