I generally avoid extensions that can read all sites (even if technically necessary), so use the suggestion found here [1] instead.

A few bookmarklets:

javascript:(function(){if (location.host.endsWith('x.com')) location.host='xcancel.com';})()

javascript:(function(){if (location.host.endsWith('youtube.com')) location.host='inv.nadeko.net';})()

javascript:(function(){if (location.hostname.endsWith('instagram.com')) {location.replace('https://imginn.com' + location.pathname);}})()
