Did you try it with no add-ons and with combinations of 2 of the 3 add-ons?

There was an update to tbird last week, which seemed OK. I have four email accounts that I download with tbird - my ISP allocated mail, my yahoo mail, and two email addresses on a server from a place I volunteer, and one of these has a major problem - every time I change to another mailbox, or close tbird, everything in the Inbox disappears. None of the other three mailboxes have this problem, all other folders (such as deleted and junk) are OK. I've made no changes to settings or properties - for retention all are set to follow account settings, which are set to leave on server (so I can at least look at the hideous webmail interface to see them), but our server will only keep them for a month. </blockquote> I've been playing with this - if I load in safe mode with no add-ons, all emails reappear. I've tried disabling each add-on in turn (there are only three) but the problem remains. If I load in safe mode but tell tbird to always load without add-ons, the problem remains. So at the moment I'm running tbird, and then choosing Help > Restart without add-ons. Any advice? TIA Dianne </blockquote> </body> </html>
