Every time I open Firefox I get the following msg "TypeError: Components.classes[cid] is undefined". How to correct this?
Every time I click on the Firefox Icon to log in, I get the following message: "TypeError: Components.classes[cid] is undefined". I click on the "OK" button and I can enter. This occurs each time I follow any links on any web pages. How can this be corrected?

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 or if hardware acceleration 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.
