keep getting error "this url is not valid and cannot be loaded" in web sites, links, favorites.
While trying to open links in email, or on websites I get this error alert. Also happening when trying to open links to web pages in favorites. Does not happen when using IE 8. I'm using Windows XP, and Norton 360

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).
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
