Kind of a click-baity title; I apologize.
For some while now I’ve been seeing the abbreviation of Firefox slowly mutate from Fx/fx to FF.
From the release notes:
How do I spell Firefox? How do I abbreviate it?
Firefox is spelled F-i-r-e-f-o-x - only the first letter capitalized (i.e. not FireFox, not Foxfire, FoxFire or whatever else a number of folk seem to think it to be called.) The preferred abbreviation is “Fx” or “fx”.
I mean, it makes total sense to abbreviate Firefox with two capital Fs, and the documentation does say “preferred abbreviation,” but I just wanted to make those of you who didn’t know about this aware…aware of the fact that you’re abbreviating Fx wrong, God dammit!
I've used FF since the first versions. It makes sense since the name is a combo of two words that start with F. I get that technically the second should be lowercase, but that looks weird. I missed Mozilla's memo on the preferred version back then…
I think with a lot of things like grammar police and such, usually if the context makes it clear what's being talked about and there's no confusion, it doesn't matter that much for informal discussion. I do admit if someone said "Fx" while talking about browser stuff, before now it would have taken a second to realize what they meant. Shows I've never seen it before.
