  • Lots to see in Firefox 93!

    Firefox 93 comes with lots of lovely updates including AVIF image format support, filling of XFA-based forms in its PDF viewer and protection against insecure downloads by blocking downloads relying on insecure connections.

  • Implementing form filling and accessibility in the Firefox PDF viewer

    Last year, during lockdown, many discovered the importance of PDF forms when having to deal remotely with administrations and large organizations like banks. Firefox supported displaying PDF forms, but it didn’t support filling them: users had to print them, fill them by hand, and scan them back to digital form. We decided it was time to reinvest in the PDF viewer (PDF.js) and support filling PDF forms within Firefox to make our users' lives easier.

  • Control your data for good with Rally

    In a world where data and AI are reshaping society, people currently have no tangible way to put their data to work for the causes they believe in. To address this, we built the Rally platform, a first-of-its-kind tool that enables you to contribute your data to specific studies and exercise consent at a granular level. Mozilla Rally puts you in control of your data while building a better Internet and a better society. 

  • Tab Unloading in Firefox 93

    Starting with Firefox 93, Firefox will monitor available system memory and, should it ever become so critically low that a crash is imminent, Firefox will respond by unloading memory-heavy but not actively used tabs. This feature is currently enabled on Windows and will be deployed later for macOS and Linux as well.

  • Time for a review of Firefox 92

    Release time comes around so quickly! This month we have quite a few CSS updates, along with the new Object.hasOwn() static method for JavaScript.

  • Spring cleaning MDN: Part 2

    Last month we removed a bunch of content from MDN. MDN is 16 years old (and yes it can drink in some countries), all that time ago it was a great place for all of Mozilla to document all of their things. As MDN evolved and the web reference became our core content, other areas became less relevant to the overall site. We have ~11k active pages on MDN, so keeping them up to date is a big task and we feel our focus should be there.

  • Hopping on Firefox 91

    August is already here, which means so is Firefox 91! For developers, Firefox 91 supports the Visual Viewport API and Intl.DateTimeFormat object additions.

  • How MDN’s autocomplete search works

    Last month, Gregor Weber and Peter Bengtsson added an autocomplete search to MDN Web Docs, that allows you to quickly jump straight to the document you're looking for by typing parts of the document title. This is the story about how that's implemented.

  • Spring Cleaning MDN: Part 1

    As we’re all aware by now, we made some big platform changes at the end of 2020. Whilst the big move has happened, it’s given us a great opportunity to clear out the cupboards and closets.
