User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; rv:33.0) Gecko/20100101 Firefox/33.0 Build ID: 20141106120505 Steps to reproduce: Trying to add account with wizard, select SSL/TLS for IMAP. Actual results: Wizard shows error "Thunderbird was not able to find settings for your account" Timestamp: 11.11.2014 14:53:42 Error: mail.souz98.ru:993 uses an invalid security certificate. The certificate is not trusted because the issuer certificate is unknown. The certificate is only valid for webrost.lgg.ru (Error code: sec_error_unknown_issuer) Expected results: Thunderburd should have displayed the "Add security exception" window to allow user to override security error, just like Firefox does. Warkaround is to first add server cert to exceptions. Then go to wizard again select the password type which enables the 'Done' button.
