Based on information from Uninstalling Firefox (mozillaZine KB)

This document will help you get set up to build Firefox on your owncomputer. Getting set up can take a while - we need to download alot of bytes! Even on a fast connection, this can take ten to fifteenminutes 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 7 or later. It is advisable to haveWindows Update be fully up-to-date.

1. System preparation¶

Firefox X86 Android

1.1 Install Visual Studio¶

Download and install the Community edition of VisualStudio 2019. If you have the Professional or Enterprise edition, thatis also supported.

Ensure you’ve checked the following items for installation:

• In the Workloads tab:

  • Desktop development with C++.

  • Game development with C++.

• In the Individual components tab:

  • Windows 10 SDK (at least 10.0.17134.0).

  • C++ ATL for v142 build tools (x86 and x64).

1.2 Install MozillaBuild¶

Install MozillaBuild.

Accept the default installation directory.Windows may prompt you to “reinstall with the correct settings”, which youshould click to accept.

When working with Firefox tooling, you’ll need to do so from within the MozillaBuildshell. You can start it by running C:mozilla-buildstart-shell.bat (you may wantto make a shortcut to this file so it’s easier to start).

Firefox X86 Download

Note

The MozillaBuild shell is a lot more like a Linux shell than the Windows cmd. You canlearn 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 Firefoxautomatically download the other dependencies it needs. The below commandwill download a lot of data (years of Firefox history!) then guide you throughthe interactive setup process.

Note

In general, the Firefox workflow works best with Mercurial. Will overwatch be for mac. 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:

This uses Git Cinnabar under the hood.

Choosing a build type¶

If you aren’t modifying the Firefox backend, then then select one of theArtifact Mode options. If you arebuilding Firefox for Android, you should also see the GeckoView Contributor Guide.

Set antivirus exclusions¶

Windows Defender and some scanning antivirus products are known to significantly degradebuild 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 havecode samples that antivirus software identifies as a threat, automaticallyquarantining/corrupting the files.

To avoid this, add two folders to your antivirus exclusion list:

• The C:mozilla-build folder.

• The directory where the Firefox code is (probably C:mozilla-source).

If you haven’t installed an antivirus, then you will need to add the exclusionsto Windows Defender.

Note

If you’re already missing files (you’ll see them listed in hgstatus, you can have thembrought back by reverting your source tree: hgupdate-C).

3. Build¶

Now that your system is bootstrapped, you should be able to build!

Firefox X86 Msi

🎉 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 tostart working on.See the Firefox Contributors’ Quick Reference to learn how to test your changes,send patches to Mozilla, update your source code locally, and more.

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 X86 Portable

Firefox will not build if the path to the installationtool folders contains spaces or other breaking characters such aspluses, quotation marks, or metacharacters. The Visual Studio tools andSDKs are an exception - they may be installed in a directory whichcontains spaces. It is strongly recommended that you accept the defaultsettings for all installation locations.

Installing Visual Studio in a different language than Windows¶

If Visual Studio is using a different language than the system, then your buildmay fail with a link error after reporting a bunch of include errors.

Mozilla Firefox X86

Quotation marks in PATH¶

Quotation marks (“) aren’t translated properly when passed to MozillaBuildsub-shells. Since they’re not usually necessary, you should ensure they’renot in your PATH environment variable.

PYTHON environment variable¶

If PYTHON is set, the build may fail with the error: “Thesystemcannotfindthefilespecified.” Ensure that you aren’t havinga PYTHON environment variable set.

Cygwin interference¶

If you happen to have Cygwin installed, its tools may erroneously beused when building Firefox. Ensure that MozillaBuild directories (inC:mozilla-build) are before Cygwin directories in the PATHenvironment variable.

Building from within Users¶

If you encounter a build failure with:LINK:fatalerrorLNK1181:cannotopeninputfile.....securitynss3.liband the Firefox code is underneath the C:Users folder, then you should trymoving the code to be underneath C:mozilla-source instead.
