It’s not FF dammit, it’s Fx!

Firefox is the browser that the world loves to love. But there is a lot of confusion regarding its spelling and abbreviation. I have seen a lot of people abbreviating Firefox as FF or even writing Firefox as FireFox.

Mozilla had done their bit to clarify the matter as far back as 2005. From their FAQ :

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”.

There you have it! Even I was unaware of this. Credit for correcting me goes to my friend [deXter]. And now you also know.

    Hi again,

    just wanted to say that I think your gravatar is cool :)

    Another thing is that your area to input the users name, mail and website are just white spaces using Fx. You see, I got it :)

    And I am going to fix this tommorow (hopefully). You are probably the 3rd reader who notified me about this issue. I am way too lazy.

    Google Fx 3.5 and FF 3.5. I generally don’t prefer using abbreviations but if I have to use it I would use something which is known to everyone (FF in this case)… doesn’t matter what Mozilla FAQ says.

    I was participating in few dicussions about “Firefox: fx or ff”. Though preferred shortcut of Firefox is fx (according to its creators) it is not so clear as it seems. Firefox has it’s own Google search page ( to be accurate: I guess it was accepted and monitored by Firefox creators, though look at the bottom hint (one of few showing randomly), the one that informing about new version of firefox. There is a image (spray can with digit 3), as we can see, spray can have dwo letters, those letters are “ff”.
