This seems to be the night-mode extension with the smallest file size, and because it's so tiny it's easy to check the code yourself to make sure it's respecting your privacy. (Download the file by right-clicking on Add to Firefox button, choose "save file", then open with an archive extractor like 7-zip).

Appreciate it for working well on Firefox Android. Of course, the plugin satisfies me on FF Desktop. Thnak you!

simple and efficient

It would be cool to be able to set different color schemes. I really would like to see option with grey out colors instead of so dark intensive! :)

Makes youtube videos so much easier to watch at night. But I wish I could still see the seek bar while it is active, it unfortunately turns opaque.

I was in the process of porting this extension. Ive liked it for a very long time. It simply blacks out most parts of a page, whereas most other extensions usually put a shade of blue or grey, and thats not enough for me.

If there is one criticism I have, it would be the fact that a white blip is shown before the addon can do its magic - as I encountered however, that is probably because of the webextension event infrastructure and not the fault of the addon.
