After installing Firefox 4.0 when trying to print get "Prop Res Dll not loaded" error message. I have a Dell A960 printer.
Installed Firefox 4.o now when I try to print and click on "properties" I get error message "Prop Res DLL not loaded". I have a Dell Printer A960. Never had this problem before so how do I fix this? I don't know that much about computers so please make it simple as I'm not that literate when it comes to complex computer fixes. thanks

See this Google search for a "fix".
Here's a Firefox bug that was filed a few months ago.

Looks like a problem caused by Lexmark print drivers doing a strange installation (Lexmark makes some of the Dell branded printers). Mozilla isn't going to revert the way Firefox looks for print drivers due to security concerns.
See if you can follow the fix posted here:
