Mozilla finally announces Firefox Nightly for Linux on ARM64

Mozilla announced that Firefox Nightly is now available for Linux on ARM64. This means users can now download the Firefox browser as binary for ARM64 (AArch64) architecture on Linux.

When Mozilla launched the Firefox Nightly .deb packages, users demanded the same for ARM64 builds. Users can access the Firefox browser as both .tar archives and .deb packages depending on their installation requirements and liking.

If you favor the traditional way, you can access the .tar.bz2 binaries on the Mozilla downloads page. To do so, you need to select the option that says Firefox Nightly for Linux ARM64/AArch64.

Whereas, for updates and installation via Mozilla’s APT repository you can follow instructions to install the firefox-nightly package.

It is worth noting that Mozilla has been quite transparent about the stabilization and development of the ARM64 builds. In a recent announcement post, Mozilla mentioned:

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.

Mozilla encourages users to download, test, and provide feedback about the new ARM64 Firefox Nightly binaries. If you find any bugs or issues while testing Firefox Nighty on ARM64, report it to Mozilla’s Bugzilla.

Doing this will aid the development process and ensure the final stable release for the ARM64 users. More recently, Mozilla strengthened security with untrusted integrity in Firefox Nightly on Windows.
