I'm using userContent.css to rewrite "about:blank" styles -> background color of it(to black).
I use "about:blank" as default page at browser start.

Since 57 update, each time I start FF, instead of getting a about:blank with black background, I'm getting about:blank with white background. After I open a newtab and switch back to about:blank, the black background color applied.

Can you please, pleeeeease fix it?

Let me use my beloved FF as I used to.

In userContent.css:
Code: Select all
@-moz-document url("about:blank") {
  body { background: black !important; }
}

In userChrome.css:
Code: Select all
/* Initial canvas color before content loads */
.tabbrowser-tabpanels {
  background: black !important;
}
