My proposol for implementation is to check for the proper paper size setting by stepping through the following items. The first successfully determined value would be used:

1 - if it exists, use a firefox-specific setting
    stored in the user's firefox profile
2 - infer paper size from LC_ALL
3 - infer paper size from LC_PAPER
4 - infer paper size from LANG
5 - if it exists, read paper size from /etc/papersize
6 - retrieve paper size from cups (if that is possible)
7 - default to a4

Comments?

I have left LC_MEASUREMENT out of this list purposely because it really has no direct bearing on paper. A user may wish to specify different measurement units, but wouldn't expect his locale's paper size to change because of that.

Step 1 - the firefox-specific setting is for users who don't care about user profiles. The user would be able to make a choice in a dialog between a specific paper size and "locale default" (or similar). This would be set to "locale default" unless the user specifically changes it.
