There are several URL shortening services these days and we come across several short URLs everywhere. The best examples are on Twitter and Facebook. But, did you ever feel that the destination of the URL isn’t safe? I’m sure you did. But, you might have clicked it straightaway or simply avoided it as you didn’t know the URL destination before clicking on it.
There’s an extension for Firefox known as Verify Redirect which allows you to see the link destination before actually clicking on it. You simply need to hover your mouse over it and it will display the link destination.
