Address bar always has a light background, even after theme changes

First image shows me using a dark theme, but address bar still has white background. Second image shows that switching to the light theme makes the text readable. However, I would still like to use a dark theme. I believe I started seeing this issue right when Firefox updated itself to version 100. Any way to fix the bugged address bar color? None of my extension should be affecting the address bar color.

That can be caused by older versions of the MaterialFox theme for userChrome.css and may require a manual tweak. https://www.reddit.com/r/firefox/comments/ujrbyg/ff_100_white_address_bar_on_default_theme/
