X/Twitter automatically replaces all posted hyperlinks with "shortlinks". So, if you post a link to "my-website.com/my-link", Twitter changes it to "t.co/xyz". This used to have some utility in the early days of Twitter, back when posts were limited to 140 characters. Now, they just serve as an annoyance and a vector to track users' clicks. Furthermore, some network filters block t.co, resulting in broken links. This extension simply replaces the t.co shortlinks with the original link.
