Firefox Nightly Build on Debian (not Ubuntu)

[Michael]

sudo apt update && sudo apt upgrade

TimeShift


sudo apt-get install mercurial

hg clone https://hg.mozilla.org/mozilla-central/

https://firefox-source-docs.mozilla.org/setup/linux_build.html

cd $HOME/mozilla-central && ./mach build -j56

Change -j56 to your actual cores, not logical cores. It will compile faster.

Compiled in 6 minutes on my dual Xeon server, no errors.
