Latest Daily update (Thunderbird replacement) loses all email settings
Daily is the name given to the new replacement for Mozilla Thunderbird. It often has daily updates, and the one today (08 Jan 2016) causes it to lose all email settings. As a result, when it start is shows no existing email, no email account, and looks like you are starting with a fresh install of a new email client.
To get around this I downloaded and installed the latest version of Thunderbird (38.5.1) and this did show all my email OK. So something bad happened to Daily - hopefully whoever it is who controls that software will fix it tomorrow.
