Как установить Firefox в мою панель запуска настольных приложений (в левом поле)? [дубликат]

Ubuntu 16.06 с обычным рабочим столом (Unity и gnome AFAIK).

Вот мой файл рабочего стола. Я пробовал довольно много разных вещей, например, наличие % u в конце файла exec. Ничего не работает. Теперь имейте в виду, что если я открою терминал и наберу / usr / lib / firefox / firefox , он наверняка запустит Firefox.

[Desktop Entry]
Encoding=UTF-8
Version=1.0
Type=Application
NoDisplay=true
Exec=/usr/lib/firefox/firefox
Name=Firefox
Comment=Firefox newset version
Icon=/usr/lib/firefox/browser/chrome/icons/default/default128.png
Terminal=false

И вот что происходит, когда я выполняю compiz --replace :
