When you installed Firefox ESR from the stable channel in Ubuntu Software you were installing the application packaged as a snap. The Software Updater and apt or apt-get commands cannot be used to manage snaps which is why you have not been offered an update.
However, when snaps are installed from the stable channel they are automatically updated. An update check runs periodically n the background. If you run the command snap info firefox in a terminal you will see a list of available snaps and the date they were released. The last line shows the version that is installed. You can force an update with the command sudo snap refresh firefox If no updates are available then an appropriate message is displayed. The latest version of Firefox ESR available is 60.8.0esr-1 which was released on 8th July. Please confirm that this is the version that is currently running on each of your machines. ** Tags added: bionic ** Changed in: firefox (Ubuntu) Status: New => Incomplete -- 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/1838199 Title: Firefox ESR in esr/stable channel is never updated by Ubuntu Status in firefox package in Ubuntu: Incomplete Bug description: Hi, I am encountering a severe issue on several Ubuntu 18.04.2 machines where I have replaced Firefox by Firefox ESR through "Ubuntu Software Center" by selecting esr/stable channel as described in https://ubuntu.com/blog/firefox-esr-60-on-ubuntu After being installed, Firefox ESR is working as expected but it is never updated. I mean Firefox ESR is detecting that a new version is available when starting. Even "Ubuntu Software Center" shows a newer version exists. But when I run either sudo apt-get update sudo apt-get upgrade or "Software Updater", Ubuntu is never updating the Firefox ESR. I have reproduced this on 3 different machines running Ubuntu 18.04.2. I am not sure if it is the right place to submit this problem report. Are you aware of this issue ?
