Ubuntu – How to install Firefox 52 ESR on 16.04

aptfirefoxsoftware installation

This question asks how to install FF32 bit while keeping the 64 bit.

I want the much more simple thing: is there a canonical way to install firefox 52 ESR as "default" firefox in my 16.04?

I found this launchpad team … but there are no packages; probably no wonder given the fact that the linked blog article dates back to 2012.

So, 2017, Ubuntu 16.04; how to install FF 52 ESR (as I simply need the java plugin to work for me).

( my current solution: I downloaded the TAR file from mozilla, extracted that to /opt; and then changed /usr/bin/firefox to be a link to that ESR version of firefox. works, but ugly )

This firefox-esr PPA works for me on Xenial: https://launchpad.net/~jonathonf/+archive/ubuntu/firefox-esr

sudo add-apt-repository ppa:jonathonf/firefox-esr-52
sudo apt-get update
sudo apt-get install firefox-esr

but please note that you will not get security updates as this version is obsolete.
