URL autofill sometimes flickers when typing the wrong case


(Firefox :: Address Bar, defect, P3)





(Reporter: adw, Unassigned)



  1. Type "" to autofill a URL like
  2. Press backspace to delete the selected part
  3. Press backspace again to delete the "s"
  4. Type an uppercase "S" and then start typing the rest of "how_bug". The case doesn't matter for the "how_bug" part.

Most of the time you try this, the rest of the "how_bug" etc. part -- which is selected -- flickers and then disappears. Step 1 seems to be necessary.

I'm guessing that it's autofilling the placeholder, and then when the search is done, it's correctly removing the autofilled part because it doesn't actually match due to the difference in case. So I would guess that the placeholder logic is incorrectly doing a case-insensitive comparison, but I haven't debugged this yet.
