My question is how to Change the color of the page that appears before a site is fully loaded. So lets say I go to a site where the background color is red. Before Firefox finishes loading it will appear as white. Also yes I known I have an add-on that changes the default color of YouTube. However the first picture happens on all sites regardless of if their background is white or not.

You can try code in userChrome.css or Stylish.

Add code to the userChrome.css file below the default @namespace line. 

@namespace url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul"); /* only needed once */

browser {background-color:#f0f0f0!important}

The customization files userChrome.css (user interface) and userContent.css (websites) are located in the chrome folder in the Firefox profile folder.

You can use this button to go to the current Firefox profile folder:

  • Create the chrome folder (lowercase) in the <xxxxxxxx>.default profile folder if this folder doesn't exist
  • Use a plain text editor like Notepad to create a (new) userChrome.css file in the chrome folder (file name is case sensitive)
  • Paste the code in the userChrome.css file in the editor window
  • Make sure that the userChrome.css file starts with the default @namespace line
  • Make sure that you select "All files" and not "Text files" when you save the file via "Save file as" in the text editor as userChrome.css.
    Otherwise Windows may add a hidden .txt file extension and you end up with a not working userChrome.css.txt file
