I've just upgraded to a version of Ubuntu that's forcing a Snap of Firefox on me. This doesn't work for me, I don't want it. I've found an alterative source for the package (mozillateam's PPA still builds) but it's being trumped by the newer epoch of 1:1snap1-0ubuntu2.
I want Apt to blacklist versions of the firefox package that contain snap.
There is another question that features a lot of the same words, but I don't see how its answer applies. That only seems to block one version. I assume there will be future 1:*snap* versions, and I don't want to play ping-pong with this.
Dupe question helps. Added this to: /etc/apt/preferences.d/99-kill-firefox-snap.
Package: firefox

Thanks all.
