Yesterday we changed the way that you create localized builds on mozilla-central.

This works for developers doing regular builds, as well as developers or localizers without a compile environment. Sadly, users of artifact builds are not supported.

For language packs, a mere

./mach build langpack-de

will work. If you’d rather wish to build a localized package, you’ll want to get the package first. If you’re building yourself, that’s

./mach package

and if you want to get a Nightly build from archive.mozilla.org, just

./mach build wget-en-US

If you want to do that for Firefox for Android, you’ll need to specify which platform you want. Set EN_US_BINARY_URL to the latest-mozilla-central-* path for the binary you want to test.

And then you just

./mach build installers-fr

That’ll take care about getting the french l10n repository, and do all the necessary things to get you a nice little installer/package in dist . Pick your favorite language from our repositories. Care for a RTL build? ./mach installers-fa will get you a Persian one 😉 .

As with other repositories we clone into ~/.mozbuild , you’ll want to update those every now and then. They’re in l10n-central/* , a repository for each language you tried.

Documentation is on firefox-source-docs.rtd, bugs go here. This works for Firefox, Firefox for Android, and Thunderbird.

And now you can safely forget all the things you never wanted to know about localized builds.
