This problem is very actual. It was discussed at least twice on AskUbuntu (see https://askubuntu.com/questions/305199/is-there-a-deb-package-to-install-firefox-esr and https://askubuntu.com/questions/505895/how-can-i-install-an-older-version-of-firefox-in-ubuntu-14-04 ).
For Ubuntu Trusty and Xenial exists new Jonathon F's PPA (https://launchpad.net/~jonathonf/+archive/ubuntu/firefox-esr). Users can install Firefox ESR with the following commands: sudo add-apt-repository ppa:jonathonf/firefox-esr sudo apt-get update sudo apt-get install firefox-esr Thank you, jonathonf! It maybe very useful because of new Firefox add-on policy. I have installed 10 add-ons and 9 of them are marked as LEGACY (see https://support.mozilla.org/en-US/kb/firefox-add-technology-modernizing ). So for enterprise users we really need ESR version of Firefox. Please make official Ubuntu package with it. ** Also affects: firefox-esr (Debian) Importance: Undecided Status: New -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/1676164 Title: REQ: firefox-esr package needed Status in firefox package in Ubuntu: Confirmed Status in firefox-esr package in Debian: New Bug description: Just like Debian offers. Ubuntu needs to offer the firefox-esr package to be taken seriously in the enterprise space. And I am sure there are a lot of users that appreciate their addons not potentially breaking that often (which is the real issue for me personally). Our organisation strongly recommends firefox users to only use ESR. This makes it hard for me to push Ubuntu within our organisation.
