  • I can still see this issue in latest version of this script, on latest Chrome.

  • Working fine in Chrome 56.0.2924.87 for Mac using Tampermonkey 4.2.7. I hope you're not using the script without Tampermonkey, as I haven't tested this for a long time.

    The unsafeWindow error makes no sense, since I'm actually checking if it's defined and "this" should not be undefined.
