When you launch TestNav in Firefox, you may see a message indicating that pop-ups are blocked (image below).

1. Click Edit Pop-Up Blocker Preferences > Content > Exceptions...
   
2. Ensure that your test website appears in the Site column, and that Allow appears in the Status column. Then, click Save Changes:
