Are you still looking for an active fork to recommend?

I'm maintaining a fork here https://github.com/lucafabbian/firepad

It's not a complete rewrite - I've just ported Firepad from the old Grunt concatenated monolithic file, to native javascript modules. I'm not planning to replace this repo, I just want to provide a modern way to import Firepad.

I also added some test, upgraded from Jasmine to Jest, added some examples and added (experimental) support for the new Codemirror 6.

Not sure if it's enough for your code standards. Let me know :)
