Description of problem:
Firefox does not check which locale it's in, and does not set paper size
acordingly (it is set to letter anyway). This is causing trouble when printing
to printers which honor the paper setting in the postscript sent to it, making
it demand me insert letter paperformat.

Version-Release number of selected component (if applicable):


How reproducible:
Every time

Steps to Reproduce:
1. Open firefox
2. Print something to a huge, expensive postscript laserprinter that cares about
papersize selected
3. It complains
4. Check printer settings in firefox
5. Letter?!?
6. Change to A4
7. Works

Actual results:
Letter no matter what

Expected results:
Should be localized. Letter in the US, A4 in europe etc. I think there is some
enviroment variable for this...
