Out of curiosity, I decided to take a look at the Firefox codebase, and compile it on my Mac. Mozilla's developer pages are great, with elaborate instructions on how to get the source code from the mercurial repository, to compiling and running the codebase on various platforms. You can find the details at: the Mozilla developer guide , and on Mac OS X they are as simple as: Get the source code from mercurial repository hg clone https://hg.mozilla.org/mozilla-central Install a specific version of autoconf (2.13) brew tap homebrew/versions brew install autoconf213 Build Firefox cd mozilla-central ./mach ./mach build The build took roughly 2 hours to finish on my MacBook Air. Run ./mach run The resulting build is similar to Firefox nightly, and includes all the bleeding edge features and instabilities, but is great for tinkering.
Musings about technology and life in general.
