One thing that irks me about the Firefox icon is how big it is when sitting in the Dock next to other icons. So I decided to modify it slightly to make it 'sit' better in the Dock...

I've shared it here if anyone wants it. Simply find the Firefox app, right/control click on it to "Show Package Contents" and go to the resources folder and replace the icon file.

Hmmm... ever noticed that the dark blue shadow of the fox (or a continent or what it is) looks like a little bunny ;-) Can you see the ears and so? I noticed it now because I took a longer look on the icon the first time... normally it's down at the bottom that I don't look at it.

@Rogue: Thanks, I'm using it.
