29.10.2018
While I much prefer git and the GitHub workflow, Firefox’s codebase (mozilla-central) is store in a mercurial repository. There are tools that wrap mercurial so you can use a git-like interface, like git-cinnabar, but my philosophy is to learn the root tool so that I know what’s going...
