I would like to replace the version of Firefox that is already installed with Firefox ESR on Ubuntu 18.04.

I have downloaded it from http://www.mozilla.org/firefox/organizations/all.html#en-US

But I couldn't configure it successfully as I could in Ubuntu 14.04:

sudo tar -xvjf firefox-x.x.tar.bz2 -C /opt
sudo ln -s /opt/firefox/firefox /usr/bin/firefox

So I have reinstalled Ubuntu completely.

How can I achieve this?

  • These commands install Firefox ESR 52 in US language: - sudo apt-get remove firefox - sudo add-apt-repository ppa:mozillateam/ppa - sudo apt-get update - sudo apt-get install firefox-esr But it worked. – christophe14 Jul 15 '18 at 20:47
