I would characterize it as a sad, kitten-lost-in-the-rain kind of look.

But yeah, I agree, not exactly a cool, edgy logo like a "firefox" or "atom"...

The puffin is one of my favorite birds (perhaps second only to the toucan), and as such, I felt compelled to recommend this browser to my friends and colleagues solely on the basis of the chosen bird.

I had to stop myself before realizing that I should learn more about the software first, maybe even try it myself.

It does indeed look a little depressed when you google for puffin picture but none the less it's a beautiful creature, makes for a good and recognisable logo.
