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.
