Just drag the Firefox icon to Applications folder icon, and here you go, now you have a portable Firefox in your Apps. dmg file, then click on it in your Downloads folder. By the way I also have portable browsers available in other languages and for other platforms like Windows, so go out check my site if you need them. If I will be forced to use a password, the password will also be published on my site.
