Firefox keeps changing printing to automatic duplex

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)?
