Imagine if you accidentally closed an important tab on internet browser and also forgotten to bookmark it.Then will you be able to find back the website? Yes, luckily the developers of web browsers has figured out this scenario and has a way for us to reopen closed tabs. Here is how you can reopen closed tabs on Firefox, Opera and Internet Explorer.
If you accidentally close a tab in Firefox, you can easily retrieve it by pressing Ctrl+Shift+T.
If you do the same mistake in Opera, Ctrl+Alt+Shift+Z will help you reopen the most recently closed tab. Or click the Trash icon near the toolbar to see a list of closed tabs arranged in reverse chronological order.
Coming to Internet Explorer, there's no inbuilt feature to restore closed tabs but there's a free add-in called IE7 Open Last Closed Tab that makes your IE 7 behave just like Firefox or Opera.
You can click Alt+X in IE and it will open up the most recently closed tab - the add-in is worth installing because you never know when you may need it. Available at Download.com
