I want to share with you that after a month of research and building of all dependencies, I finally made Firefox run on the board. It is a lot until it is fully complete, however it already can do cool stuff.
I built the main branch of Firefox with rust and cargo 1.55-dev and nodejs 14.8.
I also had help from Mozilla community so thanks to them I was able to complete this.
I’ll try to package it in the next days (and see if I can build it with more optimizations) and I pretend to share with you here.
A demo of it running can be seen here:
Cheers and stay safe
