Separate Firefox Dark UI theme from website dark mode
I like the default dark color theme in Firefox, but I prefer to view websites in light mode. This distinction has been working until recently, but with Firefox 95, the browser dark theme will enforce dark mode on websites as well. This sounds like a good default, but I want to separate the browser UI from website contents. Fortunately, there is an undocumented setting to change this behavior.
Go to "Settings" → "General" → "Website appearance" and choose your preferred setting:
Before Firefox 100, follow the following steps:
This setting defines how webpages should be rendered:
0: dark mode
1: light mode
2: system's color setting
3: browser theme color
By setting the value to
1, I can keep using the "Dark" Firefox UI theme and continue viewing websites in light mode.
