Let me put it this way...I would hate being without New Tab Tools! I've made it my home page and new tab page for Firefox on my Macbook Pro. I have a black wood background behind the tabs, which makes the whole page look really nice and is easy on the eyes. I chose a dark background for late night use, but now I use the Flux filter on my Mac to adjust the light temperature according to time of day. I just now thought of that! I'm gonna go change my backround right now. lol Anyway, the tabs look great with any background that works for you, whether picture or solid color. It is all totally customizable, from number of rows/columns, margin/grid size, title text and size, option to pin just what you tell it to or check a box to have it automatically pin visited or recently closed pages, and lock pins to keep them from being moved around or lock page to keep everything the same.
