Recently firefox has started printing everything in duplex (double sided). The print dialog that pops up when printing has the duplex box unchecked, so should print single sided.

In about:config print.printer_HP_LaserJet_4050_Series_PCL_5.print_duplex is set to 2. If I change this to 0 I get single sided printing for a random small amount of time, but at some point it reverts to 2 and duplex printing.

This does not occur in other browsers.

This sounds like a very annoying bug. Would you mind opening an account on https://bugzilla.mozilla.org/ and reporting the issue there (since that's the website the Firefox developers use to track and fix issues)?
