Reopen Recently Closed Tabs in Internet Explorer 9

Tabbed browsing is the ability to quickly switch between several open webpages within a single Web browser window by clicking on tabs. Tabs appear in the browser window when more than one webpage is opened. Each open webpage has its own tab, with the active tab displaying its page “up front,” the inactive tabs hidden behind. By clicking on a tab the user switches that page up front for quick viewing.

Tabbed browsing is extremely useful in a variety of situations. If you are reading a webpage and would like to click a link without losing your place, you can open the link in a tabbed window. After reading the link you can close the tab or just click on the original tab to switch back to the previous page, keeping both pages available. Tabbed browsing eliminates the need to repeatedly reload pages or use the “back” button.
