Hi Archy The Arcanine,

Thank you for your review and 4 stars.

All Firefox extensions do not work on the Firefox add-on gallery. That is a limit set by the Firefox web browser itself. That is also on other web browser platforms such as Google Chrome, the Chrome extensions can not customize the local page and the Chrome Web Store.
Please let me know how to get it to 5 stars.

If you need any help, please do not hesitate to contact us at https://www.turnoffthelights.com/support
We are happy to help you over there.

Thanks,

There is a Turn Off the Lights Options page, you can open it in many ways.
Solution A:
1. If you are on a web page, click 2X on the gray lamp button. You will see the mini panel show up.
2. On the bottom of this panel you see the button "Options". Click on this button will open the Turn Off the Lights Options page.
See this YouTube video tutorial:

Solution B:
1. Open the Firefox web browser and go to this URL:
about:addons
2. You will see all the installed Firefox extensions, and that include Turn Off the Lights. Now click on the horizontal 3 dot icon.
3. A menu shows up, and click on the menu item "Preferences". That will open the Turn Off the Lights Options page.

Thanks,
