Browsers are changing the default value of the
SameSite attribute for cookies from
Lax. This will greatly improve security for users. However, some web sites may depend (even unknowingly) on the old default, potentially resulting in site breakage. At Mozilla, we are slowly introducing this change. And we urge web developers to test their sites with the new default.
Firefox 79 offers a new Promise method, more secure
MDN Web Docs turns 15 years old! This celebratory article highlights fifteen big wins of the last five years. With initiatives like the browser compatibility data project, learning areas and new pathways for beginning devs, interactive examples, as well as the Product Advisory Board, the Web DNA Report, and the MDN Swag Store, the MDN community has been busy sharing knowledge with the people who build the web.
At Mozilla, we want the web to be capable of running high-performance applications so that users and content authors can choose the safety, agency, and openness of the web platform. Shared-memory multi-threading is an essential low-level building block for high-performance applications. However, keeping users safe is paramount, which is why shared memory and high-resolution timers were effectively disabled at the start of 2018, in light of Spectre. Until now...
A browser is an enormously complex piece of software, and it's always in development. About a year ago, we asked ourselves: how could we do better? Our CI relied heavily on human intervention. What if we could instead correlate patches to tests using historical regression data? Could we use a machine learning algorithm to figure out the optimal set of tests to run? We hypothesized that we could run fewer tests to save money, get results faster, and reduce the cognitive burden on developers.
When we talk about the contrast of a page, or contrast between web elements, we’re assessing how color choices impact readability. For visitors with low vision, web pages with low or insufficient contrast can be hard to use. In this article, we’ll walk through the design and implementation of the
prefers-contrast media query in Firefox, and look at why it's so exciting and important.
As part of Mozilla’s ongoing commitment to improve the privacy and security of the web platform, over the next few months, we will be making some changes to the Gamepad API. Starting with Firefox 81, the Gamepad API will be restricted to what are known as “secure contexts.”
Firefox 78 heads heads out the door with a new regex engine, updates to the ECMAScript Intl API, new CSS selectors, enhanced support for WebAssembly, some important WebExtensions API updates, and many improvements to the Firefox Developer Tools.
Mozilla WebThings Gateway is an open source software distribution focused on privacy, security, and interoperability. It provides a web-based user interface to monitor and control smart home devices over the web. OKdo, a UK vendor offerings IoT technology for hobbyists, educators, and entrepreneurs, has announced the release of the WebThings Gateway Kit, with everything you need to get the Gateway up and running in minutes.
Browser extensions give people a way to take control of how they experience the web. This week Apple has announced that Safari is adopting a web-based API for browser extensions similar to Firefox’s WebExtensions API, making it easy to build once and run in multiple browsers. Developers can get started with Firefox Extension Workshop or consult the comprehensive documentation on MDN for API coverage details.
