There are no recent crash reports. I believe this is because FF does not show it crashed so I would have the option to send a crash report. It just sits there with the print dialog box open, the hour-glass, and in the top line of FF it adds (not responding). The only way I can close it is to use windows task manager.

Try the Firefox SafeMode to see how it works there.
A troubleshooting mode, which disables most Add-ons.
Troubleshoot Firefox issues using Firefox SafeMode

When in Safe Mode...

• The status of plug-ins is not affected.
• Custom preferences are not affected.
• All extensions are disabled.
• The default theme is used, without a persona.
• userChrome.css and userContent.css are ignored.
• The default toolbar layout is used.
• The JIT Javascript compiler is disabled.
• Hardware acceleration is disabled.

• You can open the Firefox 15.0+ SafeMode by holding the Shft key when you use the Firefox desktop or Start menu shortcut.
• Or use the Help menu item, click on Restart with Add-ons Disabled... while Firefox is running.

To exit the Firefox Safe Mode, just close Firefox and wait a few seconds before using the Firefox shortcut (without the Shft key) to open it again.

thanks for the suggestion Edmeister. I opened FF in safe mode and when I try to print or even print preview it still doesn't work. It acts exactly the same as I described above..

Try doing the Reset Printer settings procedure.
