Haven’t used Libredirect, but there’s also https://farside.link https://farside.link (on GitHub: https://github.com/benbusby/farside https://github.com/benbusby/farside). Not an extension, but it redirects to an active instance for most privacy friendly front ends just by adding farside.link to the beginning (i.e. https://farside.link/https://twitter.com/elonmusk https://farside.link/https://twitter.com/elonmusk would redirect to a random active nitter instance). Also works for medium.com, YouTube, etc.
