I suspect the original poster might mean “How do I launch the Firefox Developer Edition browser?” (downloadable from https://www.mozilla.org/en-US/firefox/developer).

On Fedora, I was able to download the tarball, untar it, cd into the new directory, and then launch it from the command line like so:

curl -L --output firefox-dev.tar.bz2 'https://download.mozilla.org/?product=firefox-devedition-latest-ssl&os=linux64&lang=en-US'
tar xf firefox-dev.tar.bz2
cd firefox
./firefox

Getting it to launch from the GNOME 3 menu would require adding a desktop entry to ~/.local/share/applications/, which might look something like:

[Desktop Entry]
Name=Firefox Developer
Comment=Developer edition of the Firefox browser
Exec=/path/to/firefox-dev/firefox
Icon=/path/to/firefox-dev/browser/chrome/icons/default/default128.png
Terminal=false
Type=Application
Categories=Web;

Hope that helps!
