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.
This may be caused by pinned versions or preferences not being setup correctly in your apt config, rather than a problem with the PPA. It could have been caused by the recent 117 update.
In /etc/apt/preferences.d/ you can create files to control which versions and releases are used for which packages. This is how linux mint prevents snap from getting in, (even though they package their own firefox with its own customizations). Setting up something like:
Package: snapd Pin: release a=* Pin-Priority: -10and
Package: firefox Pin: release o=Ubuntu Pin-Priority: -10should get it working better for any further upgrades
