Default highlighted text is white on a blue background, but dark themes on Youtube, Twitter, etc seem to be inverting that to blue text on a white background in Firefox.

I'm not sure if I missed a setting somewhere, I've tried manually setting background and foreground colors for selected text, but it's still being inverted.

That is the result of a feature to ensure proper contrast. When the calculated contrast isn't enough then text and background colors are swapped. This is likely to happen when you use a dark theme.

Is there a way to disable that feature?

Alright, thanks for the help.

It looks to me like you'd have to do something like modify the value of mSufficientContrast to something low enough to ensure backLuminosityDifference is always greater. But I wouldn't know how to go about that or if its even possible to do so.
