I copied profile folder from thunderbird 60.5 in windows 10 to linuxmint 18.3 thunderbird 60.0. everything works include addons but when I want to check my emails, it prompt for password. when I enter, nothing happens (not login and checking details appears in status bar) and passwords not saved too. 1. I check Use Password Manager to remember password. 2. I deleted cert9.db, key4.db no one works.
