Training efficient neural network models for Firefox Translations
The Bergamot project is a collaboration between Mozilla, University of Edinburgh, Charles University in Prague, the University of Sheffield, and University of Tartu with funding from the European Union’s Horizon 2020 research and innovation programme. It brings MT to the local environment, providing small, high-quality, CPU optimized NMT models. The Firefox Translations web extension utilizes proceedings of project Bergamot and brings local translations to Firefox. In this article, we will discuss the components used to train our efficient NMT models.

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.

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.

Introducing Firefox’s new Site Isolation Security Architecture
Like any web browser, Firefox loads code from untrusted and potentially hostile websites and runs it on your computer. To protect you against new types of attacks from malicious sites and to meet the security principles of Mozilla, we set out to redesign Firefox on desktop.
