When I launch Firefox, I get a message stating that the " URL is invalid and will not be loaded". Clicking "OK" removes the message and then launches Firefox. How do I locate & remove the invalid URL?

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).

  • Don't make any changes on the Safe mode start window.
