Re: Server-side tagging is about hiding tracking, not advertising
lessee... if you're logging in with your Facebook or Twitter profile... with those F and T icons on that page, probably reading the cookies and identifying you anyway [whether you log in or not]. it's a fair bet they do, and phone home to momma that you went to that page.
Best thing to do, do NOT access any *BAD* *BEHAVIOR* web site (like Fa[e]ceB[ook,arph] or Tw[a,i]tter) from the context of the browser you use most often, and erase ALL of their tracking cookies and locally stored data, however you need to accomplish this. Reserve that for TRULY sandboxed browsers. see my earlier comment on how you can mitigate this using the DISPLAY environment variable in X11 environments, logging in as a special user where all history is FLUSHED when you exit the browser...
