When searching for how to install Firefox, results show how to update it (not helpful). I assume it's because Firefox USED TO BE the default browser, but now it is not installed with my version of Ubuntu (Ubuntu 16.04). So, I would appreciate clear info on the how to INSTALL Firefox question.
Question: How do I install Firefox on Ubuntu 16.04?

Open Terminal and run
sudo apt install firefox
The easiest way is to install it is to click on "ubuntu software" on the desktop, then search and install from there.
This worked for me:
$ sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys A6DCF7707EBC211F
$ sudo apt-add-repository "deb bionic main"
$ sudo apt update
$ sudo apt install firefox
