My firefox (Windows 7) doesn't let print preview work.
Today, Firefox won't let me use Print Preview. I get a pop-up notice that says Print Preview is preparing ... . Then, it times-out. This is the first time this has happened. It has always worked right away. The message also says something about Firefox being the problem.
I then checked it in IE and print preview worked perfectly. If this is a Firefox problem, shall I expect the error to be corrected by Firefox?

This might be a strange question, but do you have a antivirus on your PC? Is there a program permission that might be blocking Firefox to use your default reader?
