I get this error message when opening Firefox "onload error TypeError: TcFfUpdates.getTcPluginsInstance().getNewExtensionsList is not a function"
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).
- Don't make any changes on the Safe mode start window.

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