That kind of stuff is exactly why I’ve stopped going “dark everything.”
Some apps/websites are and will forever be WHITE and, if I use dark mode plus max screen brightness (to increase contrast), I’ll be blinded every time I open/visit one.
You know what doesn’t blind me? Using regular white pages with low brightness. Bonus points: my battery lasts longer.
Highly recommend. Also worth changing the default background color in Firefox to avoid burning your retinas every time a page loads.
