I thought FF creates it's own icon to launch? I know in Windows it does this.

You would have to add a space and this URL to the command line in a desktop shortcut that launches Firefox.

You may have to modify the Firefox .desktop file directly.

If creating a launcher then you need to manually set a image you want for what is basically a shortcut.

For the tar.bz2 from www.mozilla.org/firefox/all/ think of it as like a zip archive as there is no installer. You just extract and run the firefox .sh and you use Firefox is the basics.
