ThunderbirdPortable updated and all accounts have vanished, when executed it appears like a fresh install. Profile folder is still the expected size n GB. Checking this forum I have already tried:
(1) replacing the prefs.js file with one from a (much older) back-up, which made no difference
(2) Copy-pasting the data folder into the appropriate folder for a Thunderbird 78.0.1 desktop application, again not successful, the profile does not appear
Can anyone help guide me on how to recover my profile & emails? Thank you in advance
