We just had a power cut and now my Thunderbird Portable (78.5.0, 32-bit) is not showing any mail accounts, folders, or messages. I've checked my data\profile folder and I believe my folder structure and mail is there. In my data folder I have found prefs.js, and it has lots of relevant stuff in it, including lots of "mail.account" entries.
Can anybody help me to restore my mail please? Just for info, I use MailStore Home from time to time, but sadly not frequently enough to simply restore everything. I'd be grateful for any suggestions ...
