Troubleshooting extensions and themes

Check and tell if its working.

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.
