It happens to everyone, and it's annoying. Sometimes the wrong tab gets closed in Firefox, but it's OK. There's a solution to the problem, and it comes in the form of CTRL + SHIFT + T in Windows or COMMAND + SHIFT + T in Mac OS X.

We've covered other solutions in the past such as Unclosetab, a Firefox extension that adds a right-click option to reopen a closed tab. Another easy way to reopen a closed tab is simply to visit the Recently Closed Tabs menu under History.

And if you'd like to close the tab currently up, CTRL + W or COMMAND + W should do the trick. Now you have no excuse for your lady to catch you browsing the Apple Store late at night.
