Found this via flod’s photostream on Flickr, and I have to agree it would look nice on anybody’s computer desktop.  Also, the original file goes all the way up to 1920 x 1357, so you can resize it to fit your desktop size needs too.

Have another Firefox wallpaper you’d like to share? 

I’m not sure if this is really the world’s largest Firefox logo but I would have to say that it is pretty close! It weighs in at 9.66MB and stretches 20502 x 19839 pixels. I mirrored the image on FileHo because I didn’t want to link to the private server that Jake sent me in the tip. I furiously tried to upload it to a photo service but Flickr only allows 5MB images for free accounts and AllYouCanUpload errored out each time despite it being a restriction-free photo service.

Somebody has way too much free time on his or her hands.
