SiteAdvisor significantly slows down surfing experience. But it does not appear in the plugin list. So I am unable to disable it...

I think that I have found a way to disable it :

  • Go to about:config
  • Create a new integer
  • Enter name "plugin.state.npmcffplg"
  • Enter value 0
  • Restart Firefox

SiteAdvisor should now appear disabled in about:plugins.

Are you saying it doesn't appear in the Add-ons Manager, Plugins category? Note that it's not in the Extensions category.

That's it : it doesn't appear in the Add-ons Manager, Plugins category. But it appears in about:plugins.

You should also be able to disable this plugin in "Firefox/Tools > Add-ons > Plugins"
