What use to be the PPA that allowed Ubuntu users to use native .deb packages for Firefox has recently changed to the same meta package that forces installation of Snap and the Firefox snap package.
I am having to remove the meta package, then re-uninstall the snap firefox, then re-uninstall Snap, then install pin the latest build I could get (firefox_116.0.3+build2-0ubuntu0.22.04.1~mt1_arm64.deb) to keep the native firefox build.
I’m so done with Ubuntu.
There is not and it’s not likely, they are two different distributions that happen to use deb packages. It’s sort of like installing rpm and expecting to upgrade Ubuntu to Fedora. Maybe you could do it if you fight enough, but it’s less effort to just install Fedora.
Ubuntu-based Mint isn’t going anywhere, they just maintain them both.
