Hi I've just uninstalled Firefox as I somehow managed to have the beta version and the constant upgrades were driving me nuts. I now have 81.0 main version for Windows 10 64-bit. For many years I have kept my Profile folder on the D: drive for backup purposes. Having downgraded (by one version?) it won't let me use the old profile. Normally if I rebuild a PC or migrate, I edit %APPDATA%\Mozilla\Firefox\profiles.ini and point it to the profile on the D: drive but now I just get told to either create a new profile or exit. How can I retrieve all my bookmarks, passwords and other preferences from my old profile? Thanks John
