Hi, so I wanted my newtab page to be dark and customized it by editing the userContent.css with "@-moz-document url("about:newtab") {body { background-color: #121212 !important;}}"

It works fine when opening new tabs. The weird thing is that it doesn't change the background color of the "newtab" page that shows up when you start Firefox. I'm new to the whole userContent.css stuff so thanks for any help you can give!

There is a different internal "address" for that page. Try starting your rule this way:

@-moz-document url("about:newtab"), url("about:home") {
