A csp problem?

You can disable csp temporarily for testing with the security.csp.enable preference.

Greasemonkey

Try the Tampermonkey extension. It's working correctly in Firefox 65.

Example:

Code: Select all

// ==UserScript==
// @name         Test
// @match        http://*.mozillazine.org/*
// @grant        none
// ==/UserScript==

(function () {

  "use strict";

  var style = document.createElement("style");
  style.type = "text/css";
  style.textContent = [
    "* { background: #000000 !important; }",
    "* { color: #CCCCCC !important; }",
    "a { color: #FFCC66 !important; }",
    "a:link { color: #FFCC66 !important; }",
    "a:visited { color: #FFB720 !important; }",
    "a:hover { color: #FFFFCC !important; }",
    "a:active { color: #FFFFCC !important; }",
  ].join("\n");
  if (document.head) {
    document.head.appendChild(style);
  } else {
    document.documentElement.appendChild(style);
  }

})();

In the legacy version of Greasemonkey, it was possible to totally disable the extension and all scripts by clicking the monkey button on the toolbar. Not sure if there is anything similar to that in the WebExtensions version.
