I'm having the same problem (on multiple systems). I've remove'd firefox as a snap nut the snap still gets installed at some later point (when a new one is available?) despite the fact that my apt preferences are set to use the mozillateam-ubuntu-ppa-kinetic PPA.

I have uninstalled the snap of firefox multiple times, installing the real Firefox from ppa.launchpadcontent.net/mozillateam/ppa/ubuntu/, only for a few days later (once hours later) for snap to uninstall the real thing and install its snap version instead. I have tried a basic sudo snap remove firefox and when that didn't work sudo snap disable firefox sudo snap remove --purget firefox The former should be enough - that's a direct expression of my preferences, some thing like "You should have typed sudo snap remove --do-not-reinstall --disable-auto-ignore-preferences firefox" would not resolve this bug. When installing using apt-get, the correct version is being installed, and snap afterwards does not show the presence of firefox: Get:1 http://us.archive.ubuntu.com/ubuntu jammy/universe amd64 xul-ext-ubufox all 3.4-0ubuntu1.17.10.1 [3,320 B] Get:2 https://ppa.launchpadcontent.net/mozillateam/ppa/ubuntu jammy/main amd64 firefox-locale-en amd64 108.0+build2-0ubuntu0.22.04.1~mt1 [831 kB] Get:3 https://ppa.launchpadcontent.net/mozillateam/ppa/ubuntu jammy/main amd64 firefox amd64 108.0+build2-0ubuntu0.22.04.1~mt1 [64.9 MB] Name Version Rev Tracking Publisher Notes authy 2.2.2 12 latest/stable twilio-authy - bare 1.0 5 latest/stable canonical✓ base chromium 108.0.5359.94 2238 latest/stable canonical✓ - code 5235c6bb 114 latest/stable vscode✓ classic core 16-2.57.6 14399 latest/stable canonical✓ core core18 20221103 2632 latest/stable canonical✓ base core20 20221123 1738 latest/stable canonical✓ base cups 2.4.2-4 836 latest/stable openprinting✓ - gnome-3-28-1804 3.28.0-19-g98f9e67.98f9e67 161 latest/stable canonical✓ - gnome-3-38-2004 0+git.6f39565 119 latest/stable canonical✓ - gtk-common-themes 0.1-81-g442e511 1535 latest/stable/… canonical✓ - onlyoffice-desktopeditors 7.2.1 133 latest/stable onlyoffice✓ - snap-store 41.3-66-gfe1e325 638 latest/stable/… canonical✓ - snapd 2.57.6 17883 latest/stable canonical✓ snapd /var/lib/snapd/seed/snaps contains (once firefox is removed): core18_1880.snap gnome-3-34-1804_36.snap gtk-common-themes_1506.snap snapd_8542.snap snap-store_467.snap https://ubuntuhandbook.org/index.php/2021/10/prevent-installing-firefox-snap-ubuntu-mate-21-10/ claims that a similar issue affects Ubuntu MATE 21.04 and the solution was to type "sudo apt-mark manual firefox", which I have done, but that has not resolved the problem. I'm not here to explain why I wouldn't want the snap version, it is clearly a bug for snap to accept a command to uninstall something and then automatically reinstall it days later without the permission of the user, and especially galling that it removes the real version at the same time. I have lost data (passwords and history) because of this bug, because one of the many faults of the snap version is that it ignores the user's real ~/.mozilla profile and creates a shadow profile instead inside of the snap system. Please disable this behavior. It's obnoxious, it ignores EXPLICITY stated user preferences, and it causes the loss of data. I am unclear on what package is causing the behavior so for now marking it against Firefox, but it could be against some other piece of infrastructure related to snap: affects ubuntu/firefox To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/1999308/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
