Show HN: Disabling View Source in Firefox and Edge

• core-questions 9y ago
  For the lazy, here's the magic: <script> document.currentScript.remove(); setTimeout(function() { // no rights reserved (BSD0) by Jeremy Banks <_@jeremy.ca> const html = document.documentElement.outerHTML; document.open('text/plain'); document.write('view source disabled'); document.close(); document.documentElement.innerHTML = html; }); </script>

  Neat. How do people even discover a hack like this?

    In this case, I was trying to use `document.open()` to replace the document with some text for debugging, and I noticed some strange side effects. :) The starting point was here: https://stackoverflow.com/questions/39233344/does-javascripts-document-open-support-the-mime-type-parameter https://stackoverflow.com/questions/39233344/does-javascript...

  Also doesn't work in Safari 11.0.3.

  When I view source in Firefox I get the URL "view-source:wyciwyg://0/https://no-source.github.io/" https://no-source.github.io/" which gives me the "view source disabled" message. But if I then manually edit that in the location bar to "view-source:https://no-source.github.io/" https://no-source.github.io/" I can view the source as expected.
