I already tried making a test user and running firefox there.

Okay, this is ridiculous.  I'm running my laptop in single-head mode
at the moment, but xrandr reports

   SZ:    Pixels          Physical       Refresh
  *0   3200 x 1200   ( 602mm x 221mm )  *60
   1   1600 x 1200   ( 602mm x 221mm )   60
   2   1280 x 1024   ( 602mm x 221mm )   60
   3   1152 x 864    ( 602mm x 221mm )   60
   4   1024 x 768    ( 602mm x 221mm )   60
   5    800 x 600    ( 602mm x 221mm )   60
   6    640 x 480    ( 602mm x 221mm )   60
   7    640 x 400    ( 602mm x 221mm )   60
   8    512 x 384    ( 602mm x 221mm )   60
   9    400 x 300    ( 602mm x 221mm )   60
   10   320 x 240    ( 602mm x 221mm )   60
   11   320 x 200    ( 602mm x 221mm )   60

Setting 0 is a dual-head size.  When I did xrandr -s 1, firefox
launched fine.  Okay, the window was probably on the nonexistent other
screen... but get this: no indicator of firefox would appear in the
task panel as long as a leftover firefox process was running that was
started in the "dual head" mode.

So, problem solved, but I can't understand why I'd be in that
dual-headed mode in the first place.  Stuff like this makes me want to
get a mac :/
