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.
You shouldbea able to turn off from settings. More options are present in the config. You can find github guides doing more hardening for sedurity and privacy.
Not sure about librewolf specifically but most of these firefox forks do these initial setups for you and maybeave a couple of addons preinstalled. You would still be using firefox. Beyond crash reports and some reduced usage metrics turning them off should hinder firefox much.
