@VinsS: it looks like you manually worked around the issue, I assume you're not seeing the problem any longer?
@Paul: if you can still observe the issue on 18.04, can you please share the output of the following commands: apt policy firefox grep firefox /var/log/apt/history.log grep -H LastVersion ~/.mozilla/firefox/*/compatibility.ini ** Changed in: firefox (Ubuntu) Importance: Undecided => High ** Changed in: firefox (Ubuntu) Assignee: (unassigned) => Olivier Tilloy (osomon) -- 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/1832015 Title: firefox 67.0.1 lost my profile Status in firefox package in Ubuntu: Confirmed Bug description: On bionic, Firefox was upgraded to 67.0.1 this morning (7 June). When I launch firefox I've a message like this "Using an older version of Firefox can corrupt bookmarks and browsing history already saved to an existing profile. To protect your information, create a new profile for this installation of Firefox." And I've just one option: Create a new profile. Of course, this new profile ignore all my bookmarks, identification, password, etc. I've tried: -1 Erase the new profile folder and the installs.ini file, rewrite the profiles.ini with the name of my old profile. Same problem. -2 run firefox -p into a terminal to choose my old profile. Same problem, rejected. It's strange the message box is saying "Using an older version of Firefox", why old ?
