change findbar text background color.
I don't like the dark red background used by FF when text is not found with the find bar (it is hard to see with the forced dark theme). I would like to change the color for a lighter red, or maybe just have the cyan border turning red. and also change the default cyan border for another color.
But i don't know the css code for this.

As to your first question, you could ask on the Reddit FirefoxCSS sub if you don't get an answer here. For the second, there is a preference in about:config layout.css.prefers-color-scheme.content-override Dark (0), light (1), system (2) or browser (3) If that doesn't work, you may have to change your theme.
I don't want change the theme, it is the reason why i would also like the chromecss code to only change the page current default color (which is dark) to white.
And it is stupid to link the color mode to the theme text color, because white text is also used for almost all pastel color themes which are light.
I take it the preference doesn't help. You could try this in userChrome.css. https://support.mozilla.org/en-US/questions/1364054#answer-1473397
