Firefox Stable (currently Firefox 77) is now available in my Debian repository (which currently supports Debian 10/PureOS Amber).
With regards to FSDG: PureOS is an FSF endorsed operating system that contains Firefox-ESR (with no rebranding or modification). This leads me to believe Firefox is acceptable according to FSDG.
@polarisfm Any free software guidelines that allow stock Firefox are wrong, even if they come from the FSF.
Firefox downloads, installs, and executes proprietary blobs from third-party servers with minimal user interaction.
