Change the Findbar's search matches background / foreground color for the FOCUSED search match
Apparently, the preference names for the currently selected / focused, highlighted search match have changed. I can't find any CSS code on the web to modify this behavior. Though I made a note years ago about switching from using prefs for it in about:config, to using a CSS style.
The "unfocused" highlighted search matches do allow me to change both FG & (BG=bright pink) colors - to a point. I think I had to create these prefs, or some of them. The UNfocused search matches color prefs are: ui.textHighlightBackground #EF0FFF ui.textHighlightForeground #000000
They allow me to use black (vs. default white) for the text color on the fuchsia BG.
The pref names for focused search match apparently changed, based on an old profile. ui.textSelectBackgroundAttention #00FF00 ui.textSelectForegroundAttention #FFFFFF (I can change the white FG to anything, but it always defaults to white. The green BG w/ white FG / text, is really hard for me to read.
Fx won't allow me to change the FG color on the currently focused / selected search match. No matter if I select a BG color that black - or many non-white Foreground colors have a much higher contrast values than the default green BG w/ white FG.
Even if the colors I try have a much higher contrast value than the green / white. http://snook.ca/technical/colour_contrast/colour.html#fg=B6C9D0,bg=0004FF
EXCEPT, for the focused / selected match, if I enter white or very light BG, the super smart code still uses white text, making it invisible. But it won't let me use green / black, or yell BG with Red or Blk FG.
I think this problem is because of some algorithm Mozilla uses to calculate contrast values, that obviously doesn't work very well. Anyone know of a way around this issue, or CSS code that might override Mozilla's contrast algorithm?

Note that those prefs are for find as you type (FAYT).
More 'ui' prefs you can look at:
ui.textBackground ui.textForeground ui.textSelectBackground ui.textSelectForeground ui.textSelectForegroundCustom ui.textSelectBackgroundDisabled ui.textSelectBackgroundAttention (background for FAYT) ui.textHighlightBackground ui.textHighlightForeground
Thanks. I saw most of those (more than I wanted). What I need most is how to change the focused FG color of Findbar matches. If I make the focused BG really dark so the white text is more legible, then the current focused match is hard to locate. None of these or others I tried change the white, focused FG.
Note that those prefs are for find as you type (FAYT). See:ui.textBackground ui.textForeground ui.textSelectBackground ui.textSelectForeground ui.textSelectForegroundCustom ui.textSelectBackgroundDisabled ui.textSelectBackgroundAttention (background for FAYT) ui.textHighlightBackground ui.textHighlightForeground
Note, which "those prefs" do you mean? Besided, in Linux, if you enable "search for text when you type," when you start typing, the Findbar pops up. So they're really colors for Findbar.
If some prefs you mean include: ui.text*... : ...HighlightBackground(or Foreground), ...SelectBackgroundAttention,
they may have dual purpose - if you want to call it that. I guarantee, they are the colors for matches of terms entered into Findbar (Ctrl F on most systems & Linux).
The prefs "ui.textHighlightBackground (or Foreground) control the findbar UNfocused matches. "ui.textSelectBackgroundAttention" changes the Findbar FOCUSED match BG color. To any focused BG color you want - as long as you like a white FG with it.
I still haven't found how to change the currently focused foreground (text) color of Findbar's match. The focused FG color ALWAYS defaults to white, no matter what the BG.
Sometimes, Firefox "flips" the colors specified for focused FG & BG of matches.
I believe it's hardcoded to use white on focused matches. Nothing I've read or tried said how to override the white focused FG for Findbar match - not with prefs or CSS.
As said, it's not coded well enough, to use a FG other than white if a light BG is entered for focused findbar match. It makes text on focused matches invisible.
Don't try using something like yellow BG & red FG for focused match colors (or any high contrast, high visibility duo) - it won't allow it. It switches the red FG to white. This has been a puzzler? / irritant? for many years.
Your question post mentions these two prefs and I meant to refer to those two:
- ui.textSelectBackgroundAttention #00FF00
This pref isn't present in the source code, so it shouldn't be a surprise that this doesn't work.
- ui.textSelectForegroundAttention #FFFFFF
You can see all supported ui prefs on this page and possible do a search :
