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?

    Er, what? Firefox is most certainly still the default browser for 16.04 and comes pre-installed. – Seth Jan 18 '18 at 04:56

  • @karel OP's not asking how to upgrade an app and there's no evidence his problem is your other link. – Seth Jan 18 '18 at 17:50
  • The reason I added the second link is that in one of the answers it said that Firefox was already installed by default and if I didn't include that link then the OP could claim that this is a unique question because I didn't include a second link to confirm it, instead of a duplicate question because I did include a second link to confirm it. – karel Jan 18 '18 at 21:30

Open Terminal and run 

sudo apt install firefox

    Note: If anyone is getting `E: Package 'firefox' has no installation candidate` then you'll want to run `sudo apt update` first. –  May 16 '19 at 20:58

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 http://ppa.launchpad.net/ubuntu-mozilla-security/ppa/ubuntu bionic main"

$ sudo apt update
$ sudo apt install firefox
