It's a browser extension that does exactly what it says: makes Twitter old. And I'm not just talking about old as in getting rid of the X nonsense, I mean old Twitter. Like transporting Twitter back in time. A fun fact I learned from using it is that Twitter still has everybody's profile color preferences saved behind the scenes, if the profile is old enough to have set one. Using this, they're visible again! 10/10 would recommend.
