I want the opposite, an extension that will redirect all crappy frontends to the canonical sources (which work better and I am logged-into, I can comment, etc).

Don’t almost all of them show a link to the source anyway?

So... press the 'clone' button on the repository and swap the mapping from twitter.com -> nitter.net to nitter.net -> twitter.com?
