User Agent: Mozilla/5.0 (Windows NT 6.1; WOW64; Trident/7.0; SLCC2; .NET CLR 2.0.50727; .NET CLR 3.5.30729; .NET CLR 3.0.30729; .NET4.0C; .NET4.0E; rv:11.0) like Gecko Steps to reproduce: Then I compose a new email, I type the letters "ol" in the "To:" field. Actual results: I get a match for the email address "firstname.lastname@example.org". Expected results: The letters I type should ONLY match at the beginning of a word. The letters "ol" should never match the word "mollehem". This worked fine in the previous version of Thunderbird but is broken in Thunderbird 31.1.0. In earlier versions of Thunderbird I could type "ol" and press <Tab> and I got the correct email address. In the new version of Thunderbird I need to type "olle" and still has to select the correct recipient. This is very irritating.
Yes Daniel, we're addressing these issues in Bug 1012397 and Bug 970456 respectively. "Contains"-matches are very powerful for a lot of usecases, but we'll sort them further down into your autocomplete results so that your most likely matches should return to the top.
