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.

Disable "McAfee Site Advisor" extension which was just updated to 3.4.0, which probably took it out of the addons block list.
- "Ctrl+Shift+A" > find McAfee Site Advisor and use "Disable", and then restart Firefox.
- Do a Google Search no problem
- It seems that if you re-enable Site Advisor again, and restart Firefox you are okay. At least you know where to look if you get the error again or Google searches slow down.
