Minimizing and maximizing the browser via the windows taskbar while the search toolbar is selected will dismiss/slide in the search menu panel: STR: 1) select the search toolbar and ensure that the search menu is visible 2) minimize the browser by clicking on the Nightly icon under the windows taskbar (browser will minimize) 3) maximize the browser by clicking on the Nightly icon under the windows taskbar (the search toolbar will still be selected but the menu won't be visible) 4) Repeat #2 & #3 (this time around, the search menu will be visible, you can keep repeating the steps and the search menu will appear/disappear/appear/disappear every time you minimize/maximize) Attached a .gif that demonstrates the issue.

[Tracking Requested - why for this release]:

This is a wontfix for Firefox 34. I have marked 35+ as affected but don't think that this bug needs to be tracked.

This should have been fixed by bug 1103455

I was able to reproduce this issue on Firefox 34 Beta 11 (20141120192249) using Windows 7 x64. Verified fixed on Firefox 37.0a1 (2015-01-05) and Firefox 36.0a2 (2015-01-05) using Windows 7 x64, Mac OSX 10.9.5 and Ubuntu 14.04 x86.
