I actually think he was thinking of PhOff. [1] I actually don't really
care for it because it required me to keep it button in my toolbar,
(a space that's already way too crowded as it is.) and the color
scheme looked bad IMO. Also, IIRC, it had a problem where it wouldn't
change the color back when I switched tabs.

That said, it seems like a good first effort. It would be pretty easy
to teach grandma that she is not to type her OP's password anywhere
unless the whole top of her browser is green.
