Comment 77 for bug 10910

The file /etc/papersize is a configuration file of the groff text formatting package. It is not mentioned in any API standard. I strongly recommend that Firefox ignores groff configuration files.

This file really should have been called something like /etc/groff/papersize or, even better, groff should have used LC_PAPER instead, as proposed here for Firefox. Let's not perpetuate a mistake made in the design of groff by carrying it over into a web browser. One locale mechanism is enough. Forget about /etc/papersize.
