I am looking for a way to force dark mode on Firefox for Android.

I tried using Dark mode add-on, but it doesn't work.

Is there another way?

Try Dark Background and Light Text add-on.

This is how it looks like using the mode (it's night time for me as I write). By toggling the Aa icon on the address bar, you can enable or disable it, select the global or select sites you want affected as also modify the default scheme


@beeshyams' answer does not work as the add-on doesn't work on the android phone I have (Samsung Galaxy S10).

Dark Reader is the only add-on I can find which works
