 This is on Tails feature/jessie branch (GNOME Shell with the Classic set
 of extensions) with Tor Browser 4.5. Hardware is  a Bay Trail tablet, with
 a 800 (horiz.) x 1280 (vert.) screen according to xrandr.

 On startup, Tor Browser does a crazy resizing dance that I have a hard
 time describing. I'm pretty sure that the window is resized twice, or
 more. The warning about the dangers of maximizing the window is displayed,
 but it _very_ quickly disappears (if I wasn't looking specifically for
 such things, I would have missed it).

 Here are the logs that seemed relevant, that I could extract:

 {{{
 Window: (1,1) ?= (1212,800)
 Window is normal
 called init()
 About to resize window: 300x371 inner: 300x300 in state 3 Available:
 800x1212
 Resized new window from: 800x1000 to 800x1000 in state 3
 Mutation observer: Window dimensions are: 798x1000
 Mutation observer: Window dimensions are (after resizing again): 800x1000
 }}}

 Once I manage to connect that system to the Internet, I'll report back
 about http://browserspy.dk/screen.php findings, as requested by Mike
 Perry.
