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 nostr:npub1m5s9w4t03znyetxswhgq0ud7fq8ef8y3l4kscn2e8wkvmv42hh3qujgjl3 for this idea
