What my Firefox looks like. Click for full (Sorry people with big monitors, but the people with small ones make me have to stretch it!)

My File menu. A lot of things missing.

My edit menu. Pretty standard.

The View menu. Also standard.

Nice, neat. Just like my bedroom. NOT.

Pretty clean, empty tools menu.

Picture says it all.
