Each time I open Firefox I get the error message. I have unistalled the product, re-downloaded it and installed it with the same results. Otherwise the browser seems to work well.

Chosen solution

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

Thank you Cor-el - I disabled the "Zone Alarm Security Engine" add-on which seemed to solve the problem.
