I have been using Thunderbird for many years. Before Thunderbird upgraded me to 31.2.0 I could, when sending /forwarding e-mails, just type the 1st 1, 2 and rarely 3 letters of the recipients name into the To, CC, BCC block was enough to have the required recipients address to the top of a normally very short list and just pressing enter, left it there. Since the upgrade whatever letter I type brings out a long list of recipients who have that letter anywhere in their name or e-mail address. An example: typing in an a for Alan brings up eddie & angela@......, followed by donavan@.........., henry@global... etc etc. Alan whose address I want is 17th on a list of which has about 80% of the addresses in my address book. Had it been Ana I wanted, her name came up 28th on the list. Please fix - it must seek names alphabetically.
