Comment (by joebt):

 Additional comment:  note that at the same moment Panopticlick, etc., is
 showing an odd screen size for TBB 3.5.2 (like 1920 x '''966''' OR, if
 refresh page once, perhaps 1920 x '''96__7__'''), a full screen capture of
 the same maximized browser screen (taking up full monitor), shows 1920 x
 '''1080.'''

 The "966 or 967" TBB screen height (or whatever odd number), '''turns out
 to be''' the height for the part of browser window, beginning just below
 the browser navigation bar, down to the top of "Addon Bar."

 However, in __regular Fx__ with exact same, similarly sized toolbars
 displayed (as in TBB), the test sites  show screen size of the '''full'''
 monitor: 1920 x '''1080''', not just the "usable display area" of the
 browser pane (the part of browser window where websites actually display).

 This is a fundamental difference what test sites "see" as screen size in
 TBB vs. Firefox.

 In TBB, they see usable display area of the browser window.  In Fx, they
 see the entire monitor.
