Since updating to Firefox 4.0.1 I cannot print a web page, why?


I can print fine from regular printing but I cannot go into printer properties, it says "prop res DLL not loaded". I tried reinstalling the printer driver and same thing happens. This has been happening since I updated firefox to 4.0.1. What can I do?

I simply cannot print, either from the icon, cntrl-P, or drop down menu - nothing happens. Do not get the dll message. I have Windows 7.
