Most ergonomic keyboard layouts fall into two categories: unibody (or Alice) and split. The former is a single board with the two halves of the keys rotated about 30 degrees apart at the bottom. The separation forms an A-shaped space between the keys — which has nothing to do with why it’s called an Alice layout, it’s just a happy coincidence. This subtle tweak pushes your elbows away from your ribs while keeping a straight line from your forearm to your middle knuckle. Using one, I pretty instantly felt more open along the front side of my body. This layout more closely resembles a traditional keyboard, so it should be easier for most folks to get used to than a fully split option.

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.
