Dithering in its simplest form can be understood by observing what happens when we quantise an image with and without modifying the source by random perturbation. In the examples below, a gradient of 256 grey levels is quantised to just black and white. Note how the dithered gradient is able to simulate a smooth transition from start to end.
Fonts are a huge fingerprinting vector. We built a font allowlist and font-visibility controls; by design, Firefox's fingerprinting protection avoids using your locally installed one-off fonts on the web. This dramatically shrinks the entropy of "which fonts do you have?" without breaking normal sites. While many browsers do this now, telemetry has helped us continue to improve these defenses and I'm pretty sure we're still the only one that has a font allowlist for Android.。业内人士推荐Line官方版本下载作为进阶阅读
