i recently became aware, that lots of sites link to popular community sites via "digg this", "facebook that" etc buttons. Often those buttons are loaded directly from the site in question, which in turn is able to collect information about the user's browsing behaviour
so: is there a way to have firefox only load content, scripts and data in general from sites under the same second level domain?
ideally, there should be no way for my data so leave site-im-on.com
as i understand, firefox already prevents scripts from executing across domain borders
and i know, that this feature will break some sites, for which i'd like to have a whitelist
