Hello -

I'm looking to upgrade clients in my enterprise environment from x86 to x64. I've consulted the KB at https://support.mozilla.org/en-US/kb/profile-manager-create-remove-switch-firefox-profiles and I'm wondering if there is a way to launch this profile manager at launch, or a way to import the bookmarks from x86 to x64. In my testing, I have not seen this Profile Manager launch automatically on first run of an install of x64.

If you upgrade with Firefox, it will keep it in the Program Files (x86) directory, so this won't be an issue.

Alternatively you can use the LegacyProfiles policy or MOZ_LEGACY_PROFILES environment variable and the same profile will continue to be used.

The main problem in this case that you launch a Firefox version that is installed in a different installation folder. Current Firefox releases lock a specific profile to a specific installation folder. You can see this in the profiles.ini file and in the installs.ini file. Firefox will create a new default profile because the 64 bit version is installed in a different location.

I will move the thread to Firefox for Enterprise support.
