Hi, Usual disclaimer: the following assumes this all sticks.
I just landed bug 1515528 to autoland, which simplifies drastically how to build Firefox for arm64 windows, from a x86/x86_64 windows machine. At the moment, this requires some extra manual steps over mach bootstrap, because this doesn't work with clang-cl yet, and requires some extra MSVC components. In the MSVC installer, choose the following extra components: - Visual Studio C++ compiler and libraries for ARM64 - Visual C++ ATL for ARM64 - Visual C++ MFC for ARM64 (apologies if the names above don't match exactly what the installer shows, I translated them from my Japanese installer) While we're here, you might find it useful to know that the build system supports using Visual Studio Build Tools 2017, which is has a smaller footprint than e.g. Visual Studio Community 2017. With all the above MSVC components installed, edit a mozconfig with the following content: ac_add_options --target=aarch64 (yes, that's all) and run `./mach build`. Once the build is finished, you can run `./mach package`, and copy the resulting obj-aarch64/dist/firefox*.zip file to your arm64 machine.
