em:version="1.0"
em:name="SphereGnomeBig"
em:description="SphereGnome Big is aimed at small screens with high resolutions. It is based on SphereGnome, a cool theme with brightly colored buttons. The button icons are sized at 32x32 and 48x48, with browser icons at 24x24 (Firefox default has 16x16 browser icons). It is aimed at screen resolutions of 1024x768 through 1600x1200, and a system font of about 150% (it can handle larger and smaller system font sizes, however). Depending on your screen size, you can now pick from SphereGnome (normal), SphereGnome Big (150% normal) and SphereGnome Jumbo (200% normal). NOTE: To get a dropdown history from a forward or back arrow, right click on it. It's much easier than trying to stab at a little dropdown marker."
