Hide from EdgeHTML 12-18 "prefers-color-scheme"

WebMechanic commented 4 years ago

EdgeHTML does not handle prefers-color-scheme so it's safe to wrap things to hide from it.

regarding finger printing? That'd be Firefox not EdgeHTML.

No according to the docs on the page, the fingerprinting note shows a difference in the way this is handled if a specific firefox fingerprinting flag is enabled. "If you have set privacy.resistFingerprinting to true, prefers-color-scheme preference is overridden to light."

Below the stats on the browsers is listed properly, with Edge only showing up with versions 79+ (Chrome-based Edge)

I know, but this is to exclude EdgeHTML - v12-18 that is. No need for a value check so no fingerprinting concerns.

.not-edgy {color:lime} /* everybody */
@media (prefers-color-scheme) { 
  /* not EdgeHTML, but Gecko, Blink ... WebKit? */
  .not-edgy {color:goldenrod} 
}

It's not EdgeHTML specific, which is a bummer. There are many (older) browsers that don't support this either, so there are many ways to skin a cat: @media (color > 1) would only match recent FF and by this exclude EdgeHTML as well as many more.

However @supports not (-ms-ime-align:auto) is more Microsoft specific I guess.
