Need to know how to get my profile data reloaded into new version after upgrading. * New version does not support previous version profile data format * App startup or firefox -P in windows 10 says "Old formats are corrupted when used, create a new profile or Exit". * The profile data and folders and files are there from before the upgrade today, but Firefox does not read or support its own file formats. Examining SQLite places File format says SQLite 3 in header. * Would have been good to know before upgrading, especially as often as it prompts to do so that the key data format for a profile is not supported after upgrading. * The upgrade does not migrate, move, prompt or even warn. Just steam rolls and assumes you know Firefox's support-ability limitations and choices of its own products before running. * No information on how to get around "Old profile scan corrupt, create a new one" message on browser startup and get back to or import all my browser info (Bookmarks, Passwords, Cookies). Just tips on how to export or backup before upgrading (See "a" above)
