The use of TinyURLs for sharing links is getting popular in both Twitter and Facebook. Not only does those TinyURLs shortened the URLs of links that you share but it also these links look trendy. While this may seem alright, its usage is also prone to abuse especially in Twitter where not everyone you follow are really who they are, unless of course they were verified Twitter accounts.Fortunately, there are ways to decode this TinyURLs before you click them. One way is by using a Greasemonkey script such as TinyURL decoder.
TinyURL Decoder requires that the Greasemonkey script is installed on your Firefox browser. After installing this you can download TinyURL Decoder and install it on Firefox.
TinyURL Decoder also works with other shortened links such as PerlURL. More details about this script can be found here.
