[Bug 2027828] Re: firefox: No Firefox menu entry in MATE in the default Panel's Classic Menu (Ubuntu MATE, and Trisquel)

[David Hedlund]

** Description changed:

  This issue is easy to reproduce by running Ubuntu MATE 22.04, or
  Trisquel 11 (a distro based on Ubuntu 22.04 with MATE installed), in
  live mode.
  
  #################################
  Ubuntu MATE 22.04
  
  * MATE in the default Panel's Classic Menu: "Internet -> Firefox Web
  Browser". Selected information about the entry:
  
  /var/lib/snapd/desktop/applications/firefox_firefox.desktop
  
  Name=Firefox Web Browser
  Exec=env BAMF_DESKTOP_FILE_HINT=/var/lib/snapd/desktop/applications/firefox_firefox.desktop /snap/bin/firefox %u
  Icon=/snap/firefox/2356/default256.png
  
  ¤¤¤¤
  Remove firefox snap package
  
  [Disclaimer: snap is not the issue for this bug, because Trisquel (a
  GNU/Linux distribution based on Ubuntu) ships without snap, and Firefox
  is not added to the menu when I installed firefox (see the "Install
  firefox"). We only remove it below to make it possible to install the
  firefox ppa package.]
  
  Run these steps (from https://askubuntu.com/questions/1399383/how-to-
  install-firefox-as-a-traditional-deb-package-without-snap-in-ubuntu-22):
  
  echo '
  Package: *

  Package: firefox
  Pin: version 1:1snap1-0ubuntu2
  Pin-Priority: -1
  ' | sudo tee /etc/apt/preferences.d/mozilla-firefox
  sudo snap remove firefox
  
  echo 'Unattended-Upgrade::Allowed-Origins:: "LP-PPA-
  mozillateam:${distro_codename}";' | sudo tee
  /etc/apt/apt.conf.d/51unattended-upgrades-firefox
  
  * Menu -> Internet -- has been removed
  
  ##############################
  Install firefox from this PPA
  
  Run:
  sudo add-apt-repository ppa:mozillateam/ppa
  sudo apt update
  sudo apt install firefox
  
  * MATE in the default Panel's Classic Menu: "Internet -> Firefox Web Browser" is not added (see attached screenshot)
  * /usr/share/applications/firefox.desktop is added. Selected information about the file:
  
  Name=Firefox Web Browser
  Exec=firefox %u
  Terminal=false
  X-MultipleArgs=false
  Type=Application
  Icon=firefox

  ##############################
  Install thunderbird from this PPA
  
  This section has been added to examine why "Menu -> Internet ->
  Thunderbird Mail" but not "Menu -> Internet -> Firefox Web Browser"
  
  * Run: sudo apt install thunderbird
  * MATE in the default Panel's Classic Menu: "Internet -> Thunderbird Mail" is added. Information about the entry:
  * /usr/share/applications/thunderbird.desktop is added. Selected information about the file:
  
  Name=Thunderbird Mail
  Exec=thunderbird %u
  Terminal=false
  X-MultipleArgs=false

  Icon=thunderbird
  Categories=Application;Network;Email;
  MimeType=x-scheme-handler/mailto;application/x-xpinstall;x-scheme-handler/webcal;x-scheme-handler/mid;message/rfc822;
  StartupNotify=true
  Actions=Compose;Contacts

+ desktop-file-validate /usr/share/applications/thunderbird.desktop # No errors

  ##############################
  Temporary solution to add "Firefox Web Browser" to the menu:
  
  * cp /usr/share/applications/firefox.desktop
  ~/.local/share/applications/
