We weren't seeing a lot of folks running into this so I didn't add policy. Note that starting with 77, we did tweak the downgrade protection so it wouldn't happen with major versions: https://bugzilla.mozilla.org/show_bug.cgi?id=1588113<https://can01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fbugzilla.mozilla.org%2Fshow_bug.cgi%3Fid%3D1588113&data=02%7C01%7CEric.Periard%40cyber.gc.ca%7Cc44d8579960548c7e36108d81e8f31a2%7Cda9cbe40ec1e4997afb317d87574571a%7C0%7C0%7C637292947650523765&sdata=oMX1YvMUNcR9OVJvHDr6245wwZOvjCHY1uzjScj8lfY%3D&reserved=0> So most folks using the ESR won't see this anymore.

Hopefully this should accomplish what you need. Alternatively if it is a problem with the new Firefox being installed in a different directory, you can use the MOZ_LEGACY_PROFILES environment variable or the LegacyProfiles policy - https://github.com/mozilla/policy-templates/blob/master/README.md#legacyprofiles<https://can01.safelinks.protection.outlook.com/?url=https%3A%2F%2Fgithub.com%2Fmozilla%2Fpolicy-templates%2Fblob%2Fmaster%2FREADME.md%23legacyprofiles&data=02%7C01%7CEric.Periard%40cyber.gc.ca%7Cc44d8579960548c7e36108d81e8f31a2%7Cda9cbe40ec1e4997afb317d87574571a%7C0%7C0%7C637292947650533763&sdata=u7EbMT70SSHMsmFeiM68%2FaYkMoOTzwhRH547D5Tostc%3D&reserved=0> Mike On Wed, Jul 1, 2020 at 12:04 PM Periard, Eric <[email protected]<mailto:[email protected]>> wrote: Classification: UNCLASSIFIED Hello, Here’s an interesting situation: We’ve recently created a USMT Windows User Profile Backup and Restore package via SCCM and that works fine, however there’s a catch 22 with firefox…. Usually I keep a baseline version of the package via the Software Center and the users can update the browser via the ABOUT menu. However if a windows profile is restored to a new system (with AppData) and then firefox is installed from the Software Center, of course it’s old and it sees the newer profile as incompatible. so far the only solution I got is to go ahead and update the baseline version of my Firefox package. So here’s my questions: 1. Is it possible somehow to load a new profile onto an old Firefox? 2. Is it possible to force Firefox to look for updates as soon as someone tries to open it? 3. If 2. is possible, would it fetch the update before prompting the user to create a new profile? Please advise, this seems to be a none-issue with Chrome post-user mig.
