Remove New Tab Button

I was recently asked how to remove the ‘New Tab Button’ that appears on the far right of the tab bar. Come to think of it, I never really even use that button, I always just do CTRL+T to open a new tab. A quick search on AMO turned up this handy add-on. Remove New Tab Button. It already works with Firefox 3.6 upto Firefox 3.7a1pre.
