Hi there,

UPDATE 3 March 2020:
We take every feedback and concern very seriously. But we still did not receive any reply from you back at our official support page:

Sorry you have this bad experience.
What is the reason you rated this so low? Do you see not the lamp button? Or it doesn't dim the web page well? Have you tried to restart your Firefox web browser?

Please for questions you can use our support form: https://www.turnoffthelights.com/support
We are happy to help you over there.

Thanks,
