Kiwi Browser Shut Down,

This was a good tool to use extensions (like Nostr) on Android.

Mull was another one, but that's shut down too. Kiwi devs are now "shouting out" Microsoft Edge, but screw that.

I would now direct you to IceRaven (which Firefox based),
https://github.com/fork-maintainers/iceraven-browser

It can be used with Obtainium, which lets you use apps directly from Github. Shoutout my boy @mister_monster for this idea
