On my Kubuntu 24.04 system I’ve replaced the Firefox snap package with the proper apt one from Mozilla (https://support.mozilla.org/en-US/kb/install-firefox-linux#w_install-firefox-deb-package-for-debian-based-distributions).
I’ve done this previously on 22.04, but on do-release-upgrade to 24.04 it got undone and I had to manually set things right again. With the upcoming 26.04 release I’m wondering if there’s a way to tell do-release-upgrade to leave my installed *.deb packages on my system and not overwrite them with their snap counterpart?
