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.The post WebAssembly and Back Again: Fine-Grained Sandboxing in Firefox 95 appeared first on Mozilla Hacks - the Web developer blog.

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.The post Implementing form filling and accessibility in the Firefox PDF viewer appeared first on Mozilla Hacks - the Web developer blog.
