What is Fx? An extension?

>>copper+(OP)
“Fx” is and basically has always been (v1.5) the official abbreviation for “Firefox”. This abbreviation is basically the only one used inside Mozilla & you can see it reflected in their project names to this day.

> How do I capitalize Firefox? How do I abbreviate it?

> Only the first letter is capitalized (so it's Firefox, not FireFox.) The preferred abbreviation is "Fx" or "fx".
