Add-ons are the responsibility of their authors. McAfee does not yet have their extension on http://addons.mozilla.org that you had to install from their site.

Disable the extension "McAfee Site Advisor" who has just updated 3.4.0 that probably out of block of addons list.

  • 'Ctrl + Shift + A' > find McAfee Site Advisor and use 'Disable', and then restart Firefox.
  • Do a Google search without problem
  • It seems that if you re - enable new Site Advisor and restart Firefox you agree. At least you know where to look if you get the error again, or research on Google to slow down.
