Excuse me while I google “the FBI can eat my whole ass” 50 times per day.
Track Me Not is a Firefox add-on (and Chrome extension, but please just uninstall Chrome) that hides your activity in a cloud of noise by googling random phrases.
You can modify which search engines it uses, how often it makes searches, and even give it a blacklist of terms to not use in searches.
Thanks I added the fuck out of that.
