As you know, Firefox has been update to 57.00 but some extensions doesen't work for me. For that i want to pass 56.00 and i remove Firefox 57.00, after that i download Firefox 56.00 version and lastly i copy Firefox 56.00 folder, to there /usr/local directory.

When i give the firefox command, on command line it's work, Firefox open but there is a no icon launcher.

When i search the Firefox starter icon, i can't found anything.

Now how i can create a launcher for Firefox?

PS: I am not using Unity, i'm using XFCE.

Create a file in /home/$USER/.local/share/applications/firefox-custom.desktop, and add the follow lines of code:

[Desktop Entry]
Version=1.0
Type=Application
Name=Firefox Quantum Edition
Icon=/path/to/mozicon128.png
Exec=/path/to/executable/firefox %u
Comment=Firefox Custom 56
Categories=Development;IDE;
Terminal=false

With this when you search for it in dash you will see two launchers on for the 57 version in /usr/bin/firefox and the other for 56 custom in /usr/local

Note (confirm and adjust accordingly):

  • Icon location would be: /usr/local/firefox/browser/icons

  • Executable location would be: /usr/local/firefox

  • Hi George, i restart but this time when i click, i take a error like this. Failed to execute, command "PATH-TO-FIREFOX.SH %f". – Eindex Nov 22 '17 at 6:04
  • This "PATH-TO-FIREFOX.SH %f is just a placeholder it should contain the real path to your firefox executable like /home/<your_username>/firefox/firefox %u – George Udosen Nov 22 '17 at 6:17
  • It doesen't work again, i add my username but there is a no folder firefox on my username folder. – Eindex Nov 22 '17 at 6:32
