change print preview page size from letter to A4

Question

Firefox 9, how to switch the print preview size from letter to A4, and change all of the default "letter" paper sizes to "A4"?

Answer 1

Please write what type of operating system you use.

If you use Ubuntu Linux you can change the file /etc/papersize from

letter

to

A4

by running Terminal from the menu and typing sudo gedit /etc/papersize
