I don&#x27;t get the point of those settings. You seem to prefer white-on-black text, but the &quot;Only with High Contrast themes&quot; override means that it will almost never apply.<p>I tried setting this in my Firefox and visited a bunch of sites. None of them showed me white text on black background, because almost every site sets both background and foreground color styles, which override the preference setting. In fact the <i>only</i> site that was affected was the BMFW.<p>So what is the point of that setting? If you actually prefer white on black, set it to &quot;Always&quot; and you&#x27;ll always get it--even on the BMFW.
