If you need RPM Firefox, my recommendation is that you install it with Distrobox. This also solves the security issue that we remove upstream Firefox over - update frequency.
You don’t want Firefox to only update when your operating system image does. As far as I’m concerned the bug preventing Firefox from being re-added is a feature.
We build twice a week, that’s not frequent enough for a web browser.
Ultimately it’s saving you from yourself, if this bug gets fixed and there’s a way I can unfix it, I will do so.
