Patch for Firefox port to fix our PBIs

[Kris Moore]

Hey, we are running into this bug when trying to use FF 5.0 PBIs:

https://bugzilla.mozilla.org/show_bug.cgi?id=573958

The following patch is from the bug report thread, and should fix the 
issue we are seeing. Could this be committed to the port soon? (I've 
only eyeball compiled, may need tindy run first)

Thanks!
