Finally, to address the slow and weakly consistent S3 reads, the database leans on lock-free B-link trees. That lets readers keep moving while background checkpoints/updates by clients split or reorganize index pages. In B-link trees, each node points to its right sibling. If a checkpoint splits a page, readers just follow the pointer without blocking. Since update corruption is still a risk, a LOCK queue token ensures only one thread checkpoints a specific PU queue at a time. (I told you this is complicated.) The paper admits this is a serious bottleneck: hot-spot objects updated thousands of times per second simply can’t scale under this design.

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.
