Firefox nightly now available for Linux on ARM64
Linux distributions running on ARM have had to roll their own Firefox builds for the architecture since forever, and it seems that Mozilla has taken this to heart as the browser maker is now supplying binary ARM builds of Firefox. They come in either a tarball or a .deb package installable through Mozilla's apt repository. Do note, though, that Mozilla does not give the same kinds of guarantees for the ARM build of Firefox as they do for the x86 builds.
We want to be upfront about the current state of our ARM64 builds. Although we are confident in the quality of Firefox on this architecture, we are still incorporating comprehensive ARM64 testing into Firefox's continuous integration and release pipeline. Our goal is to integrate ARM64 builds into Firefox's extensive automated test suite, which will enable us to offer this architecture across the beta, release, and ESR channels.

These new builds won't mean much for the average ARM Linux user since distributions built Firefox for the architecture already anyway, but it does offer users a direct line to Firefox they didn't have before.
