Hi, I have been searching a way to change the Firefox new tab background image keeping its vanilla design. I found I could use a userContent.css file in this post from a few years ago: [https://support.mozilla.org/en-US/que.../1271362] I have followed the instructions step by step but it doesn't currently work.

Chosen solution

Put the wallpaper image in the same "chrome" folder as the userContent.css:

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


And don't forget changing toolkit.legacyUserProfileCustomizations.stylesheets to true in about:config (restart required).
