Getting set up can take a while - we need to download a +lot of bytes! Even on a fast connection, this can take ten to fifteen +minutes of work, spread out over an hour or two. + +If you'd prefer to build Firefox for Windows in a virtual machine, +you may be interested in the `Windows images provided by Microsoft +`_. + +Requirements +------------ + +- **Memory:** 4GB RAM minimum, 8GB+ recommended. +- **Disk Space:** At least 40GB of free disk space. +- **Operating System:** Windows 10. It is advisable to have Windows Update be fully + up-to-date. See :ref:`build_hosts` for more information. + +1. Install MozillaBuild +----------------------- + +Install `MozillaBuild +`_. + +Accept the default installation directory. +Windows may prompt you to "reinstall with the correct settings", which you +should click to accept. + +When working with Firefox tooling, you'll need to do so from within the MozillaBuild +shell. You can start it by running ``C:\mozilla-build\start-shell.bat`` (you may want +to make a shortcut to this file so it's easier to start). + +.. note:: + + The MozillaBuild shell is a lot more like a Linux shell than the Windows ``cmd``. You can + learn more about it `here `_. + +2. Bootstrap a copy of the Firefox source code +---------------------------------------------- + +Now that your system is ready, we can download the source code and have Firefox +automatically download the other dependencies it needs. The below command +will download a lot of data (years of Firefox history!) then guide you through +the interactive setup process. + +.. code-block:: shell + + # Using the C:\mozilla-build\start-shell.bat shell from step 1: + cd c:/ + mkdir mozilla-source + cd mozilla-source + wget https://hg.mozilla.org/mozilla-central/raw-file/default/python/mozboot/bin/bootstrap.py + python3 bootstrap.py +.. note:: + + When running ``bootstrap.py`` there will be a `UAC (User Account Control) prompt `_ for PowerShell after + selecting the destination directory for the source code clone. This is + necessary to add the Microsoft Defender Antivirus exclusions automatically. You + should select ``Yes`` on the UAC prompt, otherwise you will need + to :ref:`follow some manual steps below `. + +.. note:: + + In general, the Firefox workflow works best with Mercurial. However, + if you'd prefer to use ``git``, you can grab the source code in + "git" form by running the bootstrap script with the ``vcs`` parameter: + + .. code-block:: shell + + python3 bootstrap.py --vcs=git + + This uses `Git Cinnabar `_ under the hood. + +Choosing a build type +~~~~~~~~~~~~~~~~~~~~~ + +If you aren't modifying the Firefox backend, then select one of the +:ref:`Artifact Mode ` options. If you are +building Firefox for Android, you should also see the :ref:`GeckoView Contributor Guide`. + +.. _Ensure antivirus exclusions: + +Ensure antivirus exclusions +~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Microsoft Defender Antivirus and some third-party antivirus products +are known to significantly degrade build times and sometimes even cause failed +builds (due to a "missing file"). This is usually because we have tests for +well-known security bugs that have code samples that antivirus software identifies +as a threat, automatically quarantining/corrupting the files. + +To avoid this, add the following folders to your third-party antivirus exclusion list: + +- The ``C:\mozilla-build`` folder. +- The directory where the Firefox code is (probably ``C:\mozilla-source``). +- The ``%USERPROFILE%/.mozbuild`` directory (probably ``C:\Users\\.mozbuild``). + +The ``bootstrap.py`` script attempts to add the above folders to the Microsoft +Defender Antivirus exclusion list automatically. You should check that they were +successfully added, but if they're missing you will need to `add the exclusions to +Microsoft Defender Antivirus manually +`_. + +.. note:: + + If you're already missing files (you'll see them listed in ``hg status``, you can have them + brought back by reverting your source tree: ``hg update -C``). + +3. Build +-------- + +Now that your system is bootstrapped, you should be able to build! + +.. code-block:: shell + + cd c:/mozilla-source/mozilla-unified + hg up -C central + ./mach build + ./mach run + +🎉 Congratulations! You've built your own home-grown Firefox! + +Now the fun starts +------------------ + +Time to start hacking! You should join us on `Matrix `_, +say hello in the `Introduction channel +`_, and `find a bug to +start working on `_. +See the :ref:`Firefox Contributors' Quick Reference` to learn how to test your changes, +send patches to Mozilla, update your source code locally, and more. + +.. note:: + + If you'd like to interact with Mach from a different command line environment + than MozillaBuild, there's experimental support for it described + :ref:`over here `. + +Troubleshooting +--------------- + +MozillaBuild out-of-date +~~~~~~~~~~~~~~~~~~~~~~~~ + +The build system expects that you're using the most-recent MozillaBuild release. +However, MozillaBuild doesn't auto-update. If you're running into local issues, +they may be resolved by `upgrading your MozillaBuild `_. + +Spaces in folder names +~~~~~~~~~~~~~~~~~~~~~~ + +**Firefox will not build** if the path to the installation +tool folders contains **spaces** or other breaking characters such as +pluses, quotation marks, or metacharacters. The Visual Studio tools and +SDKs are an exception - they may be installed in a directory which +contains spaces. It is strongly recommended that you accept the default +settings for all installation locations. + +Quotation marks in ``PATH`` +~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +Quotation marks (") aren't translated properly when passed to MozillaBuild +sub-shells. Since they're not usually necessary, you should ensure they're +not in your ``PATH`` environment variable. + +``PYTHON`` environment variable +~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + +If ``PYTHON`` is set, the build may fail with the error: "``The system +cannot find the file specified``." Ensure that you aren't having +a ``PYTHON`` environment variable set. + +Cygwin interference +~~~~~~~~~~~~~~~~~~~ + +If you happen to have Cygwin installed, its tools may erroneously be +used when building Firefox. Ensure that MozillaBuild directories (in +``C:\mozilla-build\``) are before Cygwin directories in the ``PATH`` +environment variable. -- cgit v1.2.3
