 Cant change white background on about:newtab.  I can do this in firefox,
 but not tor browser.  I really just want the newtab page to be dark, not
 bright white. Somehow about:blank shows proper black background but not
 about:newtab.  I have dark theme selected in addons, and latest version
 torbrowser 8.0.8. Ive tried putting css styles into the chrome folder at
 root profile directory in win 10 x64:


 userChrome.css or userContent.css

 @-moz-document url("about:newtab") {
     html, body {
         background: black ;

 @-moz-document url("about:blank") {
     html, body {
         background: black ;

 How can I change the background of newtab?  Ive tried all kinds of
 variations, with and without quotes, background-color: #000000  etc cannot
 change it.
