I have a problem with Firefox Beta 52. It doesn't happen in Firefox 28. Sometimes autofill value unexpectedly appears in the end of typed search term. It happens unpredictably, however, I noticed one specific scenario when it happens 1. Open new tab, type in location bar "mozilla.org", navigate to mozilla.org 2. Open new tab, type "mmozi" in location bar 3. Move cursor to the beginning of location bar, press Delete, then quickly End Result: "lla.org/" unexpectedly appears in the end of typed search term. Text in location bar: "mozilla.org/". Expected: Textin location bar: "mozi". Autofill shouldn't appear, because if I wait a bit more before pressing End, it doesn't appear. It's impossible to control the time between pressing Delete and End, therefore it just shouldn't happen.

Marco, given that this is a backlog bug, there's not much point in tracking it in any way for 54 and 55, correct?
Right, it's an annoyance just affecting very quick typing. Not critical to fix, we have worse issues to handle first.
