get error message "url is not valid" when I go to a web pages
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 Diagnose Firefox issues using Troubleshoot Mode to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
Thank you, I'll try this.
