  • Oxidizing Source Maps with Rust and WebAssembly

    Hacks

    A detailed look at how we replaced the most performance-sensitive portions of the source-map JavaScript Library’s source map parser with Rust code that is compiled to WebAssembly. The results: The WebAssembly is up to 5.89 times faster than the JavaScript implementation on realistic benchmarks operating on real world source maps! Additionally, performance is also more consistent: relative standard deviations decreased. We hope that, by sharing our experience, we inspire others rewrite performance-sensitive JavaScript in Rust via WebAssembly.

  • Making WebAssembly even faster: Firefox’s new streaming and tiering compiler

    Hacks

    People call WebAssembly a game changer because it makes it possible to run code on the web faster. Some speedups are already present, and some are yet to come. With streaming compilation, the browser compiles the code while the code is still being downloaded. Up until now, this was just a potential future speedup. But with the release of Firefox 58 next week, it becomes a reality. Firefox 58 also includes a new 2-tiered compiler. The new baseline compiler compiles code 10–15 times faster than the optimizing compiler. Combined, these two changes mean we compile code faster than it comes in from the network.

  • Using Hardware Token-based 2FA with the WebAuthn API

    Hacks

    To provide higher security for logins, websites are deploying two-factor authentication (2FA), often using a smartphone application or text messages. Those mechanisms make phishing harder but fail to prevent it entirely. Firefox 60 will ship with the WebAuthn API enabled by default, providing two-factor authentication built on public-key cryptography immune to phishing as we know it today. The API is available today in Firefox Nightly, and it’s not too soon to start learning how to secure millions of users already in possession of FIDO U2F USB tokens.
