Olivier, it seems that the LastVersion line of compatibility.ini is the problem.
I changed 'SafeMode' to '67.0.1_20190530055249/20190530055249' as per VinsS's comment and Firefox started normally. I then restarted Firefox in safe mode and the problem returned. Reverting LastVersion to '67.0.1_20190530055249/20190530055249' enabled Firefox to start again normally. I can't remember doing so but over last weekend I must have started Firefox in safe mode which is why I didn't see the problem when I restarted Firefox immediately after upgrading on Friday(?). -- 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 ?
