Android extension

Kiwi Browser

Dots Menu -> Extensions -> + (from .zip/.crx/.user.js) -> Pick SzuruChrome-x.x.x.x.zip

Updating is a PITA because selecting a newer version zip does not 'upgrade' the older version.
It creates a new version side by side and does NOT transfer your settings. Maybe there is something I can do to fix this?

I could also consider publishing it to the Chrome Web Store, though this would cost me 5 USD.

Firefox

Cannot currently be installed, but it technically works when run in debug mode (requires USB connection to PC).
Could maybe become a thing if I publish this extension to AMO (addons.mozilla.org), see this. I contrast to Chrome, this is free.

web-ext run -t firefox-android --android-device=XXX --firefox-apk=org.mozilla.firefox

I can not believe how hard Mozilla is fucking extension developers by forcing them to use the AMO.
My extension works perfectly fine on Firefox Android, but there is no way to distribute it without using the AMO.
I want to be able to run my extension without being tethered to a PC, but I don't want to be forced to
publish my shitty extension to the public webstore.
