highlight colors change (invert) on some backgrounds, i can make it back by changing use system colors and or background color, i would like to knoe if there is a setting to stop the change ?
i set my highlight colors to yellow background and black foreground in windows , it uses the same colors in firefox except as i highlight over some colors the foreground and background colors invert yellow on black , if there is a setting (or one can be added) in about:config to make the highlight always stay as yellow back and black foreground ? , im not sure if it is done within firefox though or if it is win xp but itcan be changed inside firefox about:config with browser.display.use_system_colors and/or browser.display.background_color .

Firefox uses some algorithm to see if there is sufficient contrast difference and if not then the foreground and background colors are swapped. There is probably nothing that you can do about this apart from choosing other colors. This is the main reason for setting the Highlight all color to purple to prevent this from happening.
that sort of makes sense but when you look at youtube messages , each alternate line is a very pale blue and when highlighted each alternate line the color is switched , this also happens on all web pages with simuler shading (not just pale blue) . about the purple highlighting , ive never seen that , i have firefox on 2 PCs , a laptop and a notepad and they all use the colors set in win xp for highlight , even when use system colors is set to false , all that happens then is they swap about (invert) agen , i some times have to switch browser background color as well . sorry for being repetetive , im just trying to be clear , i have tried fine tuning BG color but on some pages just 1 single number away from white makes the switch,on other pages you can go nearly all the way to black befor it switches .ive just seen add images , ill send some pics to show what im trying to say .
