Firefox just installed the newest update (version 3.6.13) on my Dell PC running Windows 7 (64 bit). Immediately after this occurred, I cannot set any preferences for printing when printing from Firefox. It will print, but you can't set preferences like print quality or gray scale. This worked fine immediately before the update, and I also am able to access and control preferences when printing from other programs such as Word and Windows Explorer.

FYI, my printer is a Canon MX310 with latest software and drivers installed. Like I said, everything was working perfectly prior to the update install. It seems to definitely be related to this new update. Has anyone else experienced this? Any suggestions? I'm guessing it's a bug in the new update and hoping that Firefox will fix it. I love Firefox and hate having to print through Windows Explorer because of this.
