Faster Vue.js Execution in Firefox – Mozilla Hacks - the Web developer blog
Speedometer 3 is a cross-industry effort to build a modern browser benchmark rooted in real-world user experiences. Its goal is to focus browser engineering effort towards making the Web more smooth for actual users on actual pages.

Performance Tool in Firefox DevTools Reloaded – Mozilla Hacks - the Web developer blog
In Firefox 98, we’re shipping a new version of the existing Performance panel. This panel is now based on the Firefox profiler tool that can be used to capture a performance profile for a web page, inspect visualized performance data and analyze it to identify slow areas.

setTimeout()/setInterval() are now deferred during page load (Affecting) | Firefox Site Compatibility

Firefox 57 delays requests to tracking domains - mayhemer's blog
Firefox Quantum – version 57 – introduced number of changes to the network requests scheduler. One of them is using data of the Tracking Protection database to delay load of scripts from tracking domains when possible during the time a page is actively loading and rendering – I call it tailing. This has a positive effect on page load performance as we save some of the network bandwidth, I/O and C
Improving DevTools’ performance, one iteration at a time – Firefox Nightly News
Improving DevTools’ performance, one iteration at a time Firefox Quantum, released last November, was a very important milestone for Firefox. Huge performance gains were achieved by replacing parts of the engine with bits of Servo, written in Rust. But the technology shift did not stop at that: the developer tools –the inspector, the console, etc.– are being re-programmed using modern web technol
Page Visibility API - Web APIs | MDN
The Page Visibility API provides events you can watch for to know when a document becomes visible or hidden, as well as features to look at the current visibility state of the page.

Flexbox layout isn't slow | Blog | Chrome for Developers
A bit ago, Wilson Page wrote a great article for Smashing Magazine digging into how they brought the Financial Times web app to life. In the article, Wilson notes: As the app began to grow, we found performance was getting worse and worse.
