Corection: Firefox also has that feature

I was almost the first one in comment what Denker Über says on former Internet Explorer 7.

I keep on my opinion that there’s nothing new in that version. No peculiar technical advanced. Now, in full production you may found others browsers that offers you those features.

But I do a mistake, there’s an extension for Firefox that let you see in a single tab,what are browing in all the rest of the tabs. Thanks to Microsiervos on Reveal for Firefox I’ve found Reveal an extension that allows you to see thumbnails of pages in your sesion history. So may is not exactly the same, ’cause it works with history not with actual open pages but it’s almost the same and maybe with a little bit of work you may found it in a not too distant future.
