Custom Redirect

You can configure FxEmbed to redirect you to an alternative frontend such as Horizon or Nitter:

https://fxtwitter.com/set_base_redirect?url=https://xcancel.com

This sets a cookie on the domain you configure it on. If you set it on fxtwitter.com, it will not automatically apply to fixupx.com — you would need to set it separately on each domain.
