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

    Note: If anyone is getting E: Package 'firefox' has no installation candidate then you'll want to run sudo apt update first. – user606179 May 16 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
