allow @2x and @3x images to be used on about:tor
Currently, we cannot use @2x and @3x images on about:tor. This is because when privacy.resistFingerprinting
is true
the display density is spoofed to always be 1.0, e.g., a selector like the following is never activated:
@media (min-resolution: 2dppx) {
#search-button {
background-image: url('chrome://torbutton/skin/forwardArrow@2x.png');
}
}
We should figure out how to allow an exception for about:tor and other internal (but not chrome) pages.
