[Bug 2027828] Re: firefox: "Firefox Web Browser" visible in GNOME, but not in MATE

Mon Nov 27 08:42:06 UTC 2023

** Description changed:

  This issue is easy to reproduce by running live mode in:
  * Ubuntu MATE 22.04
  * or even easier in Trisquel 11 (a distro based on Ubuntu 22.04 with MATE installed) since the firefox snap package is not installed.

  #################################
  Firefox snap

  Disclaimer: This step is not needed in Trisquel (a distro based on
  Ubuntu + MATE).

  About Firefox snap package that comes with Ubuntu
  * In Ubuntu MATE 22.04: The default Panel's Classic Menu: "Internet -> Firefox Web Browser".
  * In Ubuntu 22.04: In GNOME, it's visible in the menu. It also added to Favorites.

  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://www.omgubuntu.co.uk/2022/04/how-to-
  install-firefox-deb-apt-ubuntu-22-04):

  sudo snap remove firefox

  echo '
  Package: *
  Pin: release o=LP-PPA-mozillateam
  Pin-Priority: 1001
  ' | sudo tee /etc/apt/preferences.d/mozilla-firefox

  echo 'Unattended-Upgrade::Allowed-Origins:: "LP-PPA-
  mozillateam:${distro_codename}";' | sudo tee
  /etc/apt/apt.conf.d/51unattended-upgrades-firefox

  For Ubuntu MATE: Right-click on the MATE Panel and click on "Reset all
  Panels" to remove "Firefox Web Browser".[2]

  Status:
  * Ubuntu MATE 22.04: "Firefox Web Browser" is removed from the Brisk Menu (actually the whole "Internet" category is removed from the Brisk Menu since "Firefox Web Browser" was the only item).
  * Ubuntu 22.04 (GNOME): "Firefox Web Browser" is removed from both the menu and from Favorites.

  ##############################
  Install firefox from the official PPA

  Run:
  sudo add-apt-repository ppa:mozillateam/ppa
  sudo apt update
  sudo apt install firefox

  Status:
  * Ubuntu: "Firefox Web Browser" is added to the menu.
  * Ubuntu MATE in the default Panel's Classic Menu: "Internet -> Firefox Web Browser" is NOT added (see attached screenshot). But if you copy the desktop icon, it will become visible right away in the Brisk Menu: cd /usr/share/applications/ && sudo cp firefox.desktop firefoxworking.desktop

  * /usr/share/applications/firefox.desktop is added. Selected information
  about the file:

  Name=Firefox Web Browser
  Exec=firefox %u
