XXX Where it counts
When I get a new Firefox I go into About:Config and XXX out any Http or Https (i.e xxxhttps: of xxxhttp:) link to kill those Dragons.
The worst that happens is a link in the address bar prefaced with xxx that I can remove If I give it permission to use my computer system for it's own purposes.
If any add in does not have an option to switch off calls home to mother or links elsewhere it gets the boot.
