Starting sometime after December 26, the text box isn't working properly. If I click on a text box, for example, the google advanced search page, or at the top of the bugzilla.mozilla.org page, a menu of suggestions appears. Previously I could select one of the items and it would be copied into the search box. Now a left-click (or a right-click) will select an item, but the search box remains empty, and I have to type the text into the box manually. I'm seeing this on today's nightly (38.0a1 (2015-01-12)). My previously working nightly download was December 12, but I've also seen this starting around January 5-6 with private builds from the mercurial distribution from mozilla-central.

Behavior is the same whether I enable or disable E10S. Tested with this morning's nightly.

maybe Bug 1120236 if you have removed the search bar from UI.

(In reply to Alice0775 White from comment #4) > maybe Bug 1120236 if you have removed the search bar from UI. Yup. Restoring the default search bar does indeed fix the issue reported here.

Autocomplete/dropdown is working properly now as of this morning's Nightly (18 January 2015); thanks.
