When connecting to an IMAP server that requests users identify themselves with a certificate, Thunderbird allows remembering the decision to use a given certificate, but is not able to remember the decision not to provide a certificate. The user can click "Cancel" and not send a certificate, but they will be prompted again next time. The "Remember this decision" checkbox should cause the decision not to send a certificate to be remembered.
Steps to Reproduce:
1. Install a PKCS#12 certificate.
2. Connect to an IMAP server which requests clients to use a certificate for authentication.
3. At the User Identification Request window, make sure the "Remember this decision" checkbox is checked and then click "Cancel".
When the server is connected to again later, the same dialog box prompts them again to choose a certificate to present.
When the server is connected to again later, the client should remember the decision not to send a certificate, and should not display the dialog box.
This issue is present in Thunderbird 3.0 as well as the nightly from 2010/01/05. I suspect the issue exists on all platforms but I lack resources to confirm this, so I'm submitting this as x86/Windows 7.

This may be a special case of bug 437683 (allow "no certificate" option).
