I am running Vista OS, and Mozilla Firefox. I can log in to my home page on the Internet, but whenever I go to a different web page or web site, I get a pop error message of "URL is not valid". I can click OK in the box and the page is fine. But if I go to a different internet site, this error comes back.

How do I get rid of the pop up error?

Start Firefox in Use Troubleshoot Mode in Firefox to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).

See Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems and Troubleshoot issues with plugins like Flash or Java to fix common Firefox problems
