How do I change the default backround color from white to black? AKA Stop the white flash.

more options

Whenever I open any webpage, the window turns solid white for a second before the page loads.

I am not talking about "new tab" I already have that set to use a dark theme. This is when you click on a favorite or a link on a page.

I can open a new tab with it's dark theme with no white flash but then I click on a saved favorite, and I get the white flash before any of the website loads.

PS I am using the userContent.css and userChrome.css from https://github.com/aris-t2/customcssforfx but have not found a setting for this.

Hi, I do not think you can stop that as the page needs to start loading before any settings can take effect. You may want to see Greasemonkey Extension :

None of those addons, all of which I am familiar with, can help. All of those apply CSS to specific websites.

I'm talking about the default color the browser uses for a backround "before" any part of a webpage is loaded.

Type anything, something, into the search/adress bar and hit enter.

The browser window will flash white for a second before doing anything else.

Since ancient days, I've had this in either a Stylish userstyle (pre-Quantum) or userChrome.css:

@-moz-document url(chrome://browser/content/browser.xul) {
  browser[type="content-primary"], 
  browser[type="content"] {
    background: #778899 !important;
  }
}

I do see that dark slate color from time to time, so I think it still works.

Or check the CSS for this theme which is still under active development: https://github.com/overdodactyl/ShadowFox
