Tabs are a fantastic addition to web browsing. Only a couple of years ago, if you wanted to surf more than one website, it required you to open an additional browser window. More often than not, your Task Bar was full of open browser windows. However, even with the addition of tabs, it's not particularly easy to determine the websites that you have open within each tab, as they offer a text-only preview.
Firefox Showcase 0.9 is a Firefox extension that will enable you to preview open tabs as if they are a snapshot of the website. You can quickly preview a website and go directly to that page. The only issue may be that similar open websites all appear the same, even with the preview.
