Sometimes when firefox loads a web page the error message comes up stating The URL is not valid and cannot be loaded. And I know this is a valid web site. What gives?
This happens very often. When I open Mozilla sometimes I get an error stating that "The URL is not valid and cannot be loaded." When I click ok the site stops loading and the tab is titled untiled.

This can be a problem with DDE.
