Hello, Point (1) is indeed to be expected, because the 'firefox' deb package provided by Ubuntu itself (which has a purpose of serving as a thin wrapper around the Firefox snap and adding some system integration for it) has a version 'epoch' of '1' (e.g. in '1:1snap1-0ubuntu5' that is the '1' before the ':'), whereas the deb package from Mozilla's repositories has the default epoch of '0'. Therefore to dpkg, the one with the higher epoch (i.e. Ubuntu's) is seen as newer. As such, I believe specifying '--allow-downgrades' is necessary when installing the one from the Mozilla repos.
As for (2), I believe that should not happen if you set up apt pinning to prioritize the Mozilla repository (step 5 of their instructions). Can you please double-check that you performed that step? ** Changed in: firefox (Ubuntu) Status: New => Incomplete -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/2069486 Title: [snap] Firefox snap is reinstalled on a new release To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/2069486/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
