Whenever I click on firefox, or when a pop-up occurs, I get a java script error that says, "TypeError: Components.classes[TvtPwmComponent_CID] is undefined". I don't know why. It first occurred while I was on ESPN while trying to watch college games live.

This issue can be caused by an extension that isn't working properly.


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).
