I just noticed this today, which does not mean it has not been there. On firefox, there is a new item that displays ‘meta’ and share information on the website you are on. Also, when you click on the pull down bar; it gives you a list of (I guess) your most recent pages. I have not looked into this in any real detail, although I did take a quick visit to Firefox and see if its somehow connected to the awesome bar, but i did not see anything.. Well, nothing jumped out at me.
So anyway, I’m sure everyone is seeing it about now, if not, then pull up FF and have a look.
