Firefox and the extraterrestrial robots robotrons are secretly planning, preparing and conspiring for an alien robotronic invasion. Don't you believe me? OK, its normal for you to question the truth of my account and I am here with the proof. Firefox guys were apprehensive about the ulterior motives of the robots so they built a back door for them selves in case some thing goes wrong. So now I am going to share that secret with you but careful not to leak it because it would not be a secret any more not to mention that it will piss off the robots.
Here you go. Go to your location bar in your Firefox window and type about:robots and voila! So now you believe me? There are some more secret doors hidden some where over there and now its up to you to find out all those and save the world.
Warning: And please don't press the button if it says so or else you may trigger the alarm.
P.S: Did you notice the title of the page. Its "Klaatu barada nikto" and those are the exact same words that Klaatu told to Helen in the movie The day the earth stood still(1951), to stop the robot Gort from destroying the earth. Now memorize these words and one day they may save you from the clutches of the Robotrons.
