Went low-key public with our internal browser project by sharing here on the feddit. If you're a dev, packager, Arch Linux user, or already build Firefox from source, this is for you^1^. More people using it becomes a shared privacy win. I humbly suggest that this is currently the most privacy-friendly general-purpose GUI browser out there^1^.
^1^: Others can check back at a later date when perhaps there are more builds running and tested, and more people have looked over the code.
^2^: Biased? I would never!
