Would you take a look at this article please :

I guess I am not clear as to the Reddit connection regarding Night / Dark option. My interest was for the Firefox application being in Dark Mode. It seems that what you are telling me is that Reddit is the application whereby the Night/Dark Mode is activated and not on the Firefox site per se. Is this thinking correct? As you can see by the screen shot, I cannot find any "button" to change this page to Dark Mode.

Please supply the URL you downloaded from, Thanks

You said that you installed the Enhancement Suite - which one of these are you talking about (if at all) :

https://addons.mozilla.org/en-US/firefox/search/?platform=windows&q=Enhancement%20Suite

All... I found what I was looking for in Firefox's "Theme" section. See screen shot. My suggestion is that Theme option be mentioned if this question comes up. Not sure why Reddit or Verge kept coming up in the discussion but, I found the simple solution within the Firefox Add-On's / Options section. Thanks for your assistance and trying to help me out.

Hi, why it came up in the discussion as there are many ways to get a dark mode : userchrome is one :

I'm still wondering why you said :

" I installed the Enhancement Suite " ....... (?)

When I searched for Add-On in Firefox it said to add Enhancement Suite which I thought was for Firefox but, I learned that the Suite I added was the Reddit Enhancement Suite which was not necessary. My bad! but thanks to everyone for helping me through this and to have a "lesson learned".
