If this is about a userContent.css theme, make sure it targets about:newtab in addition to about:home.

@-moz-document url(about:home), url(about:newtab) {
  body {
    --newtab-background-color: red !important;
  }
}

If you use an image, use this in userContent.css in the chrome folder in the Firefox profile folder.

@-moz-document url(about:home), url(about:newtab) {
  body {background: url("wallpaper.jpg") center/cover no-repeat fixed !important;}
}
