I don't why (as i have not altered any settings). But now when i use Mozilla firefox browser, a lot of websites are being displayed with a blark/dark background. I know it is the firefox browser as it does not do the same if i use other web browsers. I tried looking up the issue and solutions. All i could find was some suggestion that websites are displayed according to the settings on my PC i.e if it is set to light or dark mode. I checked this and the settings have not changed. Also as previously mentioned, then if that was the reason, surely the websites would display dark when using another browser. I have attached a screen shot of the twitter website as an example.

Isisombululo esikhethiwe

OK, it's dark theme and now webpages follow it. If you want to keep it, enter "about:config" in the URL bar and set layout.css.prefers-color-scheme.content-override to 2 or 1.

Check if you have a dark theme selected in ≡ -> Extensions and themes -> Themes.

Not that i can see. As mentioned i have not been messing about with any settings anyway. But from the theme installed there isn't even a "light/Dark" option available that i can see

Do you mean the creator changed the theme to a dark theme? Because like i said, i have had the them for well over 12 months now and ive never had this issue until the other day.

Also i have checked by disabling it and enabling other previous themes ive used and the websites are still displaying the same.

Firefox 96 and newer look at the text color used in the toolbar area (tab bar) and if the text color is a light color (white) then the Firefox devs decided that you prefer to use a dark background and light text on webpage and thus switches to a dark theme. If you set layout.css.prefers-color-scheme.content-override = 1 (dark:0, light:1, system:2, browser:3) you override this for webpages to use a light theme.

Thanks for explaining.


Also Thank you TyDraniu for the solution
