That would upset sugar daddy Google.

Why not get the flatpak?

Security concerns. There’s a lot of debate over it, but from the research I’ve done, I believe the Flatpak of Firefox is less secure, since it seems to remove part of Firefox’s internal sandboxing, and relies heavily on Flatpak’s sandboxing.

Basically makes it easier to compromise your data within the browser (like cookies, site data, passwords, etc), but maybe harder to get to the rest of your OS.

I just prefer using the rpm of Firefox with Firejail, as that keeps Firefox’s built-in sandboxing intact, while adding an extra layer similar to Flatpak to restrict it further. Best of both worlds.
