I've scoured the internet for the past half hour to find as many funny firefox pictures as I can. All pictures were taken from Flickr, I have added a link underneath every image to the submitters profile:
Protection is very important!
Ah, a crop circle!
I always knew MS didn't like FF but come on, this is childish!
That cat looks too cosy!
Launch Firefox! Launch Firefox! Launch Firefox!
Extension Galore, Is Google Toolbar there?
She is now fully protected!
That's all I can find for now, hopefully you have had a little laugh. If you know of any more please add them as comments.
Oh, and of course, I have added a link to the image and profile of all of the images so that you can look at the submitters other images.
