Fifeldor: So how can one disable Google Analytics?
On Firefox you can use NoScript (and put it in the Always Deny list) and/or Ghostery, Ghostery is probably an easier extension to use. NoScript is probably generally better for you if you're willing to surf the web that way (i.e. you have to play, "guess which scripts make the features I want on this site actually work"), especially on multimedia sites it's a pain at first, you get pretty used to it.
Ghostery, though, it's a cinch, definitely use it.
EDIT: I forgot to say, of course you can use both in conjunction.
EDIT EDIT: That Facebook "Like" button that shows up everwhere (and the Login button) actually is capable of tracking you if you're still logged into Facebook on the same browser, be aware of that too. You don't have to click it for it to track you, the mere fact your browser loaded it in the way Facebook asks sites to load it is enough.
