Firefox’s New WebSocket Inspector

Filed under
Moz/FF

The Firefox DevTools team and our contributors were hard at work over the summer, getting Firefox 70 jam-packed with improvements. We are especially excited about our new WebSocket inspection feature, because you told us in feedback how important it would be for your daily work.

To use the inspector now, download Firefox Developer Edition, open DevTools’ Network panel to find the Messages tab. Then, keep reading to learn more about WebSockets and the tricks that the new panel has up its sleeve.

But first, big thanks to Heng Yeow Tan, the Google Summer of Code (GSoC) student who’s responsible for the implementation.

Linux Kernel Security in a Nutshell: How to Secure Your Linux System

The Linux kernel is the core component of the Linux operating system, maintaining complete control over everything in the system. It is the interface between applications and data processing at the hardware level, connecting the system hardware to the application software. The kernel manages input/output requests from software, memory, processes, peripherals and security, among other hefty responsibilities. Needless to say, the Linux kernel is pretty important. However, with power comes great responsibility, and the Linux kernel is no exception to this rule. Kernel security is critical: it determines the security of the Linux operating system as a whole, as well as the security of every individual system that runs on Linux. Vulnerabilities in the kernel can have serious implications for Linux users, and it is extremely important that users stay up-to-date on news and advisories pertaining to kernel security. Read more

Mozilla: Webcompat, Firefox 71, Privacy Advice and Rust

  • Karl Dubost: Saving Webcompat images as a microservice

    Thinking out loud on separating our images into a separate service. The initial goal was to push the images to the cloud, but I think we could probably have a first step. We could keep the images on our server, but instead of the current save, we could send them to another service, let say upload.webcompat.com with a HTTP PUT. And this service would save them locally.

  • Multiple-column Layout and column-span in Firefox 71

    Firefox 71 is an exciting release for anyone who cares about CSS Layout. While I am very excited to have subgrid available in Firefox, there is another property that I’ve been keeping an eye on. Firefox 71 implements column-span from Multiple-column Layout. In this post I’ll explain what it is and a little about the progress of the Multiple-column Layout specification. Multiple-column Layout, usually referred to as multicol, is a layout method that does something quite different to layout methods such as flexbox and grid. If you have some content marked up and displaying in Normal Flow, and turn that into a multicol container using the column-width or column-count properties, it will display as a set of columns. Unlike Flexbox or Grid however, the content inside the columns flows just as it did in Normal Flow. The difference is that it now flows into a number of anonymous column boxes, much like content in a newspaper.

  • The Mozilla Blog: Can Your Holiday Gift Spy on You?

    Mozilla today launches the third-annual *Privacy Not Included, a report and shopping guide identifying which connected gadgets and toys are secure and trustworthy — and which aren’t. The goal is two-fold: arm shoppers with the information they need to choose gifts that protect the privacy of their friends and family. And, spur the tech industry to do more to safeguard consumers. Mozilla researchers reviewed 76 popular connected gifts available for purchase in the United States across six categories: Toys & Games; Smart Home; Entertainment; Wearables; Health & Exercise; and Pets. Researchers combed through privacy policies, sifted through product and app specifications, reached out to companies about their encryption and bug bounty programs, and more. As a result, we can answer questions like: How accessible is the privacy policy, if there is one? Does the product require strong passwords? Does it collect biometric data? And, Are there automatic security updates?

Graphics and GPUS: NVIDIA, Intel and Vulkan

  • CUDA 10.2 Released With VMM APIs, libcu++ As Parallel Standard C++ Library For GPUs

    NVIDIA has released CUDA 10.2 for SuperComputing 19 week. CUDA 10.2 comes with some interesting changes, including to be the last release that will support Apple's macOS and the introduction of a standard C++ library for GPUs.

  • Intel Iris Plus Ice Lake Graphics Run Great With Mesa 19.3's Gallium3D Driver

    While Mesa 19.3 was the original target for switching to the Intel Gallium3D driver by default for Broadwell and newer, they shifted that goal to Mesa 20.0 to allow more time for testing and ensuring a bug-free experience as users transition from the classic "i965" driver over to "Iris" Gallium3D. But even so if running with Mesa 19.3 today it means better performance for Ice Lake as well as Gen8 and Gen9 hardware too.

  • Vulkan post-processing layer vkBasalt has a new release up with SMAA support

    Continuing to boost the feature set of the post-processing layer for vkBasalt, a new release is up and it appears we missed a few smaller in-between releases too. Version 0.2.0 was released yesterday, adding in support for SMAA which is a higher-quality form of anti-aliasing which can be enabled in the config file. With that in vkBasalt now supports: Contrast Adaptive Sharpening, Fast Approximate Anti-Aliasing and Enhanced Subpixel Morphological Anti-Aliasing so it's advancing quite quickly.
