Set mail.password_protect_local_cache to true. restart and get prompted twice for your master password. dmose you are cced because standard8 told me you where seeing something similar.

I get prompted three times for the master password every time I start Thunderbird. mail.password_protect_local_cache is set to false. If I type the right password and cancel either of the other two prompts, I get a prompt for one of my mail account passwords. I have four IMAP accounts with "check for new messages at startup" checked; all but one of those uses SSL/TLS. Coincidence? This is driving me crazy. I'm running TB 3.0.3 on Windows XP.

I've never touched the local_cache pref at all. I've seen behavior like this when I have Lightning enabled, but (I think) not otherwise. This is presumably because Lightning wants to get saved passwords for remote calendars. Do you guys have a similar setup? Mark, is the work you're doing around prompting stuff likely to fix this for Lightning as well?

I do run Lightning and have one remote calendar stored on Google.

bug 349641 is the Lightning bug for the master password

comment #0 is a bug about not having lightning as it is reproducible in -safe-mode .

Is this a dupe of bug 338549?

(In reply to comment #6) > Is this a dupe of bug 338549? Not really but the issue is fixed so dumping to it.
