An explanation of the Firefox Source Code Directory Structure and links to project pages with documentation can be found at: https://firefox-source-docs.mozilla.org/contributing/directory_structure.html For information on how to build Firefox from the source code and create the patch see: https://firefox-source-docs.mozilla.org/contributing/contribution_quickref.html If you have a question about developing Firefox, and can't find the solution on https://firefox-source-docs.mozilla.org/, you can try asking your question on Matrix at chat.mozilla.org in `Introduction` (https://chat.mozilla.org/#/room/#introduction:mozilla.org) channel. Nightly development builds can be downloaded from: https://archive.mozilla.org/pub/firefox/nightly/latest-mozilla-central/ - or - https://www.mozilla.org/firefox/channel/desktop/#nightly Keep in mind that nightly builds, which are used by Firefox developers for testing, may be buggy.

Bug 40857: Modified the fat .aar creation file This is a workaround to build fat .aars with the compiling enviornment disabled. Mozilla does not use a similar configuration, but either runs a Firefox build and discards its output, or uses artifacts build. We might switch to artifact builds too, and drop this patch, or write a better one to upstream. But until then we need this patch. See also https://bugzilla.mozilla.org/show_bug.cgi?id=1763770. Bug 41458: Prevent `mach package-multi-locale` from actually creating a package macOS builds need some files to be moved around with ./mach package-multi-locale to create multi-locale packages. The required command isn't exposed through any other mach command. So, we patch package-multi-locale both to prevent it from failing when doing official builds and to detect any future changes on it.
