It's not working for me at all.

I have tried this addon twice in a year, still having the issue that FF Netflix/the window is freezing like every 15sec., sometimes also the subtitle getting freezed, so few seconds later all the delayed text just run over the display. Uninstalled after 30min right away. Good idea, but buggy. P.S.: Learning mode should have trial mode/test mode, otherwise I won't just pay for something I have no idea how it's working. Keep up, I hope I will install it once again sometimes. :)
