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.
Unfortunately this does not work on "card" links.
