You can use Tampermonkey on Firefox mobile to run these scripts. I just installed both of them they work great!

While I personally agree with you on desktop Firefox, Firefox on Android (or at least most user-facing versions of it), have a curated list of approved addons and it’s generally impossible or at best incredibly difficult to install any addons outside that list. Tampermonkey is included but Violentmonkey is not.
