AR:  Toolbars hide with smooth transition
ER:  Either X or Y (reporter believes only X is logical)
 X) Toolbars should hide without transition after Step 4 in each scenario
 Y) Toolbars should always hide with transition in Step 2 in each scenario (i.e. value "2". See below)

Note (some history with explanation):
 First of all, there was a pref "browser.fullscreen.animateUp" that defined the way toolbars hide when
 browser switches to fullscreen. Possible values were:
 0 - no transition, 1 - transition only the first time toolbars hide, 2 - always transition
 Currently only values 0 and 1 are allowed, and the pref was renamed to "browser.fullscreen.animate"
 Value "true"  of the new pref represents value "1" of the old pref;
 Value "false" of the new pref represents value "0" of the old pref.
 So regardless of how that pref is called now, the behavior defined by the pref should be respected.
