The JavaScript Specification has a New License – Mozilla Hacks - the Web developer blog
Ecma International recently approved the 2022 standard of ECMAScript. There is something new in this edition that hasn’t been part of prior editions, but this isn’t a new programming feature. In March of this year, Ecma International accepted a proposal led by Mozilla for a new alternative license. On June 22nd, the first requests to adopt this license were granted to TC39 and applied to the follo
A new year, a new MDN – Mozilla Hacks - the Web developer blog
If you’ve accessed the MDN website today, you probably noticed that it looks quite different. We hope it’s a good different. Let us explain! MDN has undergone many changes in its sixteen-year history from its early beginning as a wiki to the recent migration of a static site backed by GitHub. During that time MDN grew organically, with over 45,000 contributors and numerous developers and designers
Version 100 in Chrome and Firefox – Mozilla Hacks - the Web developer blog
Chrome and Firefox will reach version 100 in a couple of months. This has the potential to cause breakage on sites that rely on identifying the browser version to perform business logic. This post covers the timeline of events, the strategies that Chrome and Firefox are taking to mitigate the impact, and how you can help. User-Agent string User-Agent (UA) is a string that browsers send in HTTP he

Welcoming Safari to the WebExtensions Community – Mozilla Hacks - the Web developer blog
Browser extensions provide a convenient and powerful way for people to take control of how they experience the web. From blocking ads to organizing tabs, extensions let people solve everyday problems and add whimsy to their online lives. At yesterday’s WWDC event, Apple announced that Safari is adopting a web-based API for browser extensions similar to Firefox’s WebExtensions API. Built using fami
CSS Scroll Snap Updated in Firefox 68 – Mozilla Hacks - the Web developer blog
When Firefox 68 goes to general release next month, it will ship with an updated CSS Scroll Snap specification. This means that Firefox will support the same version of the specification as Chrome and Safari. Scroll snapping will work in the same way across all browsers that implement it. In this post, I’ll give you a quick rundown of what scroll snapping is. I will also explain why we had a situa
ES modules: A cartoon deep-dive – Mozilla Hacks - the Web developer blog
ES modules bring an official, standardized module system to JavaScript. It took a while to get here, though — nearly 10 years of standardization work. But the wait is almost over. With the release of Firefox 60 in May (currently in beta), all major browsers will support ES modules, and the Node modules working group is currently working on adding ES module support to Node.js. And ES module integra

The whole web at maximum FPS: How WebRender gets rid of jank – Mozilla Hacks - the Web developer blog
The Firefox Quantum release is getting close. It brings many performance improvements, including the super fast CSS engine that we brought over from Servo. But there’s another big piece of Servo technology that’s not in Firefox Quantum quite yet, though it’s coming soon. That’s WebRender, which is being added to Firefox as part of the Quantum Render project. WebRender is known for being extremely

Ruby support in Firefox Developer Edition 38 – Mozilla Hacks - the Web developer blog
It was a long-time request from East Asian users, especially Japanese users, to have ruby support in the browser. Formerly, because of the lack of native ruby support in Firefox, users had to install add-ons like HTML Ruby to make ruby work. However, in Firefox Developer Edition 38, CSS Ruby has been enabled by default, which also brings the support of HTML5 ruby tags. Introduction What is ruby? I

A call for quality HTML5 demo markup – Mozilla Hacks - the Web developer blog
HTML5 is a necessary evolution to make the web better. Before the HTML5 specs were created we used (and still use) a hacked together bunch of systems meant for describing and linking documents to create applications. We use generic elements to simulate rich interaction modules used in desktop development and we make assumptions as to what the user agent (browser) can do for the end user. The good
Firefox 4: HTML5 Forms – Mozilla Hacks - the Web developer blog
Firefox 4 will come with better support for HTML5 forms. In the latest beta we are experimenting with a set of new features: more inputs types (email, url, tel, search), new attributes (placeholder, autofocus, list), decoupled forms and different validation mechanisms. This is thanks mostly to the hard work of Mounir Lamouri. Some examples will work in other browsers, but you’ll need Firefox 4 bet
