WebAssembly and Back Again: Fine-Grained Sandboxing in Firefox 95
In Firefox 95, we're shipping a novel sandboxing technology called RLBox — developed in collaboration with researchers at the University of California San Diego and the University of Texas — that makes it easy and efficient to isolate subcomponents to make the browser more secure. This technology opens up new opportunities beyond what's been possible with traditional process-based sandboxing, and we look forward to expanding its usage and (hopefully) seeing it adopted in other browsers and software projects.

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.

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.

Getting lively with Firefox 90
As the summer rolls around for those of us in the northern hemisphere, temperatures are high and unwinding with a cool ice tea is high on the agenda. Isn't it lucky then that Background Update is here for Windows, which means Firefox can update even if it's not running. We can just sit back and relax! Also this release we see a few nice JavaScript additions, including private fields and methods for classes, and the at() method for Array, String and TypedArray global objects. This blog post just provides a set of highlights.
