De-t.co is a free Chrome extension developed by johnpbloch that aims to simplify the process of unshortening t.co URLs on Twitter. This handy tool automatically expands all t.co links on a page, eliminating the need to manually click on each one to see the full URL.

Twitter's URL shortener, t.co, can sometimes be slow or unresponsive, causing frustration for users who want to quickly access the original link. With De-t.co, this issue is taken out of the equation, saving users time and effort.

One of the key features of De-t.co is its limited scope of operation. The extension only runs on twitter.com and its subdomains, ensuring that it focuses solely on enhancing the Twitter browsing experience.

While De-t.co is primarily a background script, the developer has added a touch of whimsy by including a screenshot of kittens. This adds a bit of visual appeal and charm to the extension.

Overall, De-t.co is a useful and straightforward Chrome extension that effectively unshortens t.co URLs on Twitter, providing users with easy access to the original links they want to explore.
