"But clacke, aren't you that kind of fedi hypocrite who still runs twitface? And isn't invidious sometimes just broken/blocked?"

Sure am! And it is!

Rather than flipping those redirects on and off, I just use Klar, and also Bromite or Fennec in Incognito Mode, as my hypocrite browsers, and if a video is broken in inviduous, just copy the link and run it in NewPipe instead of the browser, and I get that popup or background functionality so I can fry my attention neurons and see that conf presentation while also browsing fedi.
