=> ↺ Firefox 113 significantly boosts accessibility performance
About five years ago Mozilla shipped Firefox Quantum, an upgrade that included significant performance improvements for most Firefox users. Unfortunately, Firefox Quantum didn’t improve performance for people who use screen readers and other assistive technology. In some ways, our screen reader performance actually regressed with the architecture changes that Quantum delivered.
Browsers are more complicated today than when Firefox’s accessibility engine was first designed, and the most significant overall change has been the move to security-isolated, multi-process architectures. With multiple isolated processes, screen readers had to do a lot of expensive work to retrieve and relay content to users. We were inspired by Chrome’s approach and extended it to improve Firefox’s accessibility performance; Firefox now provides a cache of all tab and browser UI content to screen readers in the browser’s parent process, where it can be used quickly and very easily.
This blog post by accessibility tech lead Jamie Teh provides more context and technical details on the project, but the largest impact you’ll notice immediately is speed. For some of the worst use cases — like pages with very large tables — Firefox now performs up to 20 times faster, and we’re clocking other very large pages at 10 times faster! However, even for the most everyday actions, like opening and closing a Gmail message or switching channels in a Slack window, the performance is 2 to 3 times better.

Content moderation at scale is impossible to do well. And, contrary to what most people believe, a huge part of content moderation is not “we have to suppress this content that scares us,” but just an attempt to “stop people from being jerks to others.” Unfortunately, too many people get confused, and think that “free speech” means they get to commandeer private property to be assholes to others, which results in confusing fights over people claiming their “free speech” is under attack when the reality is that a private property owner has decided you need to stop being an asshole.

Mozilla has released security advisories to address vulnerabilities in Firefox and Firefox ESR. A cyber threat actor could exploit some of these vulnerabilities to take control of an affected system.
