IE7 Open Last Closed Tab is a free plugin for Internet Explorer 7 to reopen the last closed tab. This is very useful when you accidentally close a tab that you didn’t mean to close.

With the IE7 Open Last Closed Tab plugin, you don’t have to search through your internet history to find the page you were just on, just hit “Alt-X” and the accidentally closed page automatically reopens in a new tab.

It also supports a Quick Tab Style View, shown when you hit “Alt-Q”, which gives you thumbnails of the previous tabs you’ve closed (like the built-in IE Quick Tabs, but for previously closed tabs). Click on one of the thumbnails from this view, and the page will open in a new tab.
