 cant modify browser default background color - about:blank, about:newtab,
 about:config. nothing.  Stuck with glaring white screen every time I watn
 to open a tab in tor browser.  This needs to be resolved.  I contacted
 firefox about this too.  apparently this file userContent.css in the
 chrome folder under tor browser root profile folder, doesnt do anything.
 It works in latest firefox on windows 10, it doesnt eliminate white flash
 when loading a page, but at least newtab is dark when I open a new tab in
 FF.  This issue isnt specific to me. its GLOBAL.  If someone can find a
 solution would be appreciated.

 @namespace
 url("http://www.mozilla.org/keymaster/gatekeeper/there.is.only.xul");
 @-moz-document url("about:newtab"), url("about:blank")
  { body {background-color: #000000 !important;} }


 @-moz-document url(chrome://browser/content/browser.xul)
  { browser[type="content-primary"] {background-color: #000000 !important}
 }
