Hi!
I have 2 partitions in my system, C: which is restored after every reboot (using Deep Freeze) and D: which holds all my portable applications.
I've clean-installed Portable Thunderbird 3.0 in D: and the first time I created an account, a "Add Security Exception" window appeared for IMAP server, so I clicked "Confirm security exception" and ticked "Permanently store this exception".
The thing is that every time I reboot, the first time I launch Thunderbird, this window still appears!
Is this info not stored in the Thunderbird directory?
I have the same issue. At my workplace, our email server is mail.example.com. However, the actual servers are mail1.example.com and mail2.example.com, and the SSL certificates give those names. When I access the mail server with IMAPS, Thunderbird accesses mail.example.com but is presented with a certificate for whichever server is actually being used. Thunderbird gives a security warning every time, regardless of whether I check "permanently store exception". And it doesn't just happen once per boot; it happens multiple times per session, at seemingly random intervals. I used to use the "Remember Mismatched Domains" extension for Thunderbird, but it doesn't work with 3.0.
