As you know Mozilla has launched its new Firefox 3, this new browser is faster and it has interesting features. So, the next version Firefox3.1 browser will bring a new kind of window display. With the [Ctrl]+[Tab] buttons you can navigate through the active windows, which gives new effects to this new browser.
When pressed those buttons it shows a little pop up menu with the active window and other windows that are in second plan (the last visited websites) will stay side by side of the main window, well, it works like the Apple style.
