Geminize, a Firefox addon for the Gemini Protocol

That depends on how you define native. If you ship an add-on that uses
"native messaging"[1] to talk to a companion app (such as a console python
script), then you can have the companion app do the gemini protocol dance
and send the data back to Firefox.

What sucks is that you can't have the add-on install the native companion
app for obvious security reasons, but if you can convince your user to run
an installer, then it is all very easy. When I was developing some SSB
add-on toys for Firefox, I initially used this approach and it worked fine.
Later I started using WebSockets to talk to the SSB server instead which
was much easier for the user. Still, using native messaging works, and it
works across platforms and across browsers. Oh, an in the subject of
add-ons, I vaguelly remember something about  Brave is exposing sockets to
add-on developers, you might want to check it out.

I'm sad about libdweb as well. I was one of the contributors. It had so
much potential, Mozilla totally dropped the ball.
