Martin Husemann came up with data for the patch below, and it makes a 
difference for me. At least when running 
work.i386/mozilla//dist/bin/firefox, i still get fireworks by just running 
"firefox"... weird.

I've placed some evidence at http://www.feyrer.de/Misc/firefox15.gif.

I need some sleep now.
