Here is a little more about the theme from the developer:

ANTHEM is a fun little side project I recently started. It was inspired by my blog layout and the popular “dark” look that has taken over in the past few years. The icons are 100% original. However, some windows still use the original theme buttons.

Using Windows here, there are a few features that are a little buggy it seems – but I this is a great start to a very nice looking theme for Firefox.

You can check out the author’s official site and then pick the theme up from the Firefox Add-ons repository.  Also, for more dark theme selections, go check out the list of the most popular dark Firefox themes.

The Kempelton Large theme for Firefox delivers in the big button department for sure. You can still get a little ‘bit smaller icons if you go with the ‘Use Small Icons’ option when using this theme. Use the standard Kempelton theme instead if you want a more typical icon size.

Do you like the big buttons?

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.
