iOS user here.
Tack me up for yet another "who cares"
Safari does an excellent job on iOS, especially with all the tweaks from jailbreaking. ie Tab+, Safari Download Manager, Omnibar etc.
We also have the option of Chrome with it's own jailbreak tweaks to make it default, have it's own download manager intot he raw file system like SDM, etc.
Firefox had it's time, but right now I'd easily take Chrome on any platform over Fx.
PS: It's Fx, not FF.
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".
