Bump... I never get responses when I ask a question Idk if I'm being unclear or not?

Bump...

Maybe the problem is that there's no built-in way to do it. Other people have noted that the dark theme is incomplete, and I don't know the time frame for making it extend to built-in pages, sidebars, etc. For now, you can use a combination of custom style rules which allow you to modify the default properties of Firefox's built-in style sheets.

Here's an example: https://www.reddit.com/r/firefox/comments/6s2l0w/removing_the_white_flash_before_a_page_loads/

I realize the author of that posted a warning about form fields. I haven't tried it myself so I don't know what the issue is.

More info on the userChrome.css file if you've never created one before: https://www.userchrome.org/

Thanks it looks like that fix is working for people, I'm trying it now. Edit: I installed it and it works every except new tab but honestly that's good enough for me thanks for the help!
