If you are using a slow or unreliable internet connection, hg clone might fail because it gets interrupted. See the documentation explaining how to enable the Mercurial progress extension. This will provide feedback during the lengthy clone process. This may take a while it's a lot of code! We recommend that you add the progress extension to your Mercurial configuration. Get the latest source code from Mozilla's Mercurial code repository. Once you have all the dependencies installed, you need to clone the Firefox repository. You can re-run the bootstrap script to print this information again later. For now, copy this configuration text and continue on.

The bootstrap script will print out configuration options for you when it finishes more on this below. The bootstrapping script will install system packages, the Android SDK (and NDK, if required), and the currently required versions of the Android platform and extras. Or, if you have wget installed instead: wget -q & python bootstrap.pyĬhoose Firefox for Android when prompted. If you have curl installed (note that Mac OS X ships curl by default): curl -O & python bootstrap.py You'll need Python version 2.7 or later and curl or wget. Run either of the following in a terminal. If you're going to install Firefox for Android on a physical Android device, you'll need one running Android Ice Cream Sandwich (API 15) or later.As of early 2015 it is no longer possible to build Firefox on most 32-bit machines. You must have a 64-bit operating system.Artifact mode regularly downloads large (50MB) binary archives. Both the development environment and the source code repository are quite large. Fast broadband internet is strongly recommended as well.If you have older hardware, it is strongly recommended that you use artifact mode.

While you can build Firefox on older hardware it can take quite a bit of time to compile on slower machines, and having at least 8GB of RAM is recommended.

If you're interested in building on Windows, or can contribute, please CC yourself onto bug 1169873.

There is no hard reason that it should not be possible (now in the past, it was not possible because Google did not release certain parts of the Android toolchain for Windows), but it's also not a priority. Building Firefox for Android on Microsoft Windows is not yet supported.
