For Facebook, after having deleted and blocked all Facebook-related cookies in Firefox, Internet Explorer and Google Chrome, I use Opera for everything I do on Facebook, or on sites that use Facebook for logins or comments. It allows me to segregate the rest of my Internet experience from Facebook, and Opera has a handy-dandy Facebook ad blocker addon available, so it cleans up my screen real-estate too!
That how we fix this.
Technology got us into this mess, and using it wisely can get us out of it.
