Comment 133 for bug 10910

Maybe people in the US don't see this as a serious issue, but in the rest of the world it is, even though most of Ubuntu now has good localisation at install time, Firefox is completely out the loop.

There are more people in the world for whom A4 is the default size. It's the ISO standard. And regardless of that, FF should be picking up defaults from the system -or asking the printers themselves- rather than assuming US letter. The fact that this issue has been going on for so long is just painful.
