My upgrade from 15.0 to 15.1 crashed (long story, short version: remove USB backup disk before upgrade!), so I did not do an upgrade, but a complete backup of my ‘home’ directory (in 3X) before doing an install. My question is: How to restore all mail data in ‘Thunderbird 15.0’ into ‘Thunderbird 15.1’? Additional info: I have disabled ‘KWallet’ in 15.1 as well as in 15.0.
Your Thunderbird emails are in .thunderbird/<unique_sequence>.default. If you have done a fresh install, Thunderbird may have given you a new <unique_sequence>.default into which you may have to copy the contents of the old <unique_sequence>.default in your backup.
Sorry for using all caps. More intelligent: I should have simply said (in lowercase!) don’t reply, the mail is ill conceived. The idea was to shout at myself, not at others. Sorry!
