Two Firefox profiles with different icons

  1. Create two profiles (one as a default profile), you can use:
    • Go to about:profiles in Firefox.
    • Run firefox --ProfileManager --no-remote from terminal or ALT+F2
  2. Remember names of your profiles (e.g. personal and business - I assume profile business is a default profile - it means that hyperlinks outside Firefox browser will open in this profile)
  3. Create a personal desktop shortcut with different names and icons
    • Find an original Firefox desktop shortcut file: locate firefox.desktop - it should be something like /usr/share/applications/firefox.desktop
    • Create your personal profile desktop file: cp /usr/share/applications/firefox.desktop ~/.local/share/applications/firefox-personal.desktop
    • Change line Name=Firefox to something like Name=Firefox Personal
    • Change all lines with Exec=firefox ... to Exec=firefox --class=firefox-personal --no-remote -P personal ...
    • Change line Icon=firefox to something like:
      • Icon=firefox-trunk-alt
      • or any other icons from your icon theme find /usr/share/icons/ -iname "firefox*"
  4. Business profile will be the default profile with default icon, name, etc.
  5. Now you should see a two icons in your Gnome3 menu and two icons in your ALT+TAB and Dash panel (if you have it).
