When going from the "Home" page to play Mafia Wars, I receive the message "Invalid URL" Can go back to Home page alright, but cannot return to Mafia Wars.

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

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