The popup appears and must be acknowledged, before I can move to the next screen, subject etc. A pain..........

Chosen solution

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

Cor-el, you solved my problem. I did MOST of what you told me to do, AND IT WORKED. MANY, MANY THANKS! I appreciate the time you took to help a fellow Firefox user--above and beyond!
