Title:
  Firefox icon missing from panel following Kubuntu upgrade 20.04->22.04

Status in firefox package in Ubuntu:
  Confirmed
Status in ubuntu-release-upgrader package in Ubuntu:
  Fix Released
Status in firefox source package in Jammy:
  New
Status in ubuntu-release-upgrader source package in Jammy:
  Fix Committed

Bug description:
  [Impact]

  By removing the firefox deb and installing the snap instead, ubuntu-
  release-upgrader is subverting the logic of the firefox transitional
  deb.

  [Test Case]

  Perform an upgrade from focal to jammy:

  $ do-release-upgrade

  On an affected system, the firefox deb will be removed by the upgrade,
  and the snap will be installed instead. On a fixed system, ubuntu-
  release-upgrader will not remove the firefox deb, and the deb will
  handle the transition to the snap.

  [Where problems could occur]

  If the patch was wrong, e.g. JSON syntax error or similar, it could
  mess up the remaining deb2snap entries.

  [Original Description]

  1) lsb_release -rd

  Description:    Ubuntu Jammy Jellyfish (development branch)
  Release:        22.04
  (Kubuntu Jammy live session in QEMU VM)

  2) apt-cache policy ubuntu-release-upgrader-core
  ubuntu-release-upgrader-core:
    Installed: 1:22.04.6

  3) expected

  (upgrade from Kubuntu 20.04.3 -> 22.04. Reboot.)

  * Firefox icon on panel to be intact.
  * Clicked icon launches browser.
  * Icon tooltip/mouse hover to describe application.

  4) happened instead

  * Icon is missing/replaced with a generic icon
  * Icon click produces error notification "Plasma Workspace - preferred://browser"
  * Icon tooltip/mouse hover appears, though is blank.

  Additional info:
  * firefox is still installed, works as expected.
