URLs (web links) that have been shortened are very common these days. This is
very convenient on services like Twitter. But there is always a chance that
bad guys have hidden a malicious link this way. So if you are you worried
that some shortened URL might actually lead to a malicious site, you might
want to try this quick and easy way to find out where a shortened URL
actually goes. It's a browser extension for Chrome and Firefox. Once
installed, it provides a right-click context menu entry "Unshorten this link"
that will reveal the true identity of a suspicious URL. It also provides
safety ratings and information about the destination website as well as the
actual URL. It displays a page with the WOT safety rating, shows any
blacklist mentions of the URL, and provides a screenshot of the web page that
the URL opens.
