Good news, I pulled the latest source and built to find a problem downloading my email and you have fixed the problem.... Bad news. I am getting the following when changing to slug folder from the source (now) build, note that Mozilla was crashing on a move to this folder (see good news). More good news, just deleted slug.msf and it all works again. Error messages follow... mailbox://foskey@mail/slug JavaScript error: line 7: uncaught exception: [Exception...
