Extract the file to the /opt folder of your Ubuntu by using the following command as sudo:

$ sudo tar xjf ~/FirefoxSetup.tar.bz2 -C /opt/

Unpack the Firefox Archive

Now, create a Firefox executable in /usr/lib/ that points to the location where you extracted the .tar.bz2 file (the /opt folder). Use the following command to do so:

$ sudo ln -s /opt/firefox/firefox /usr/lib/firefox/firefox

Create Symlink to Firefox binary

Launch Firefox

Run the following command in your Terminal in order to launch Firefox:

$ firefox

Remove

In order to remove Firefox installed through this method, run the following command as sudo in your Terminal:
