Firefox creator Blake Ross offers the following tale:

If you put my grandfather in a room with God and gave him one question, he would not ask for the meaning of life. He would not inquire as to the existence of poverty or the vagaries of human nature. No, he would ask, and I quoth: Do you use Firefox? My grandfather, an avid watcher of our SpreadFirefox counter, claims to have personally converted the 4 million people in his “inner circle,” or what we call “Florida.” God would make 4 million and one.
So when I returned from the airport bathroom two weeks ago, I was hardly surprised to find him (my grandfather, not God) engaging the head Rabbi of Israel in a delightful conversation about Firefox. We knew it was the head Rabbi because moments earlier the man had been shepherded into the Admirals Club by six (6) police officers, and my grandfather asked one of the cops…if he used Firefox. Then he asked the cop who the man was.
I returned from the bathroom just in time to hear my grandfather say: “I use Firefox religiously. Have you heard of it?”
Religiously. To the head Rabbi of Israel. Wince. Wince. Wince. Cut to me stuffing my head between my knees, wondering if my grandfather and a Rabbi were going to get in a fistfight, pondering whose side the six cops were going to take, then wondering if my grandfather would evangelize Firefox to his fellow prisoners.
“Firefox?” The Rabbi stops and thinks for a minute, rubbing his beard. “Ah yes! The one that blocks all the schmutz.”
