• 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.

• 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.

Mozilla Rally puts you in control of your data while building a better Internet and a better society. The post Control your data for good with Rally appeared first on Mozilla Hacks - the Web developer blog.

This feature is currently enabled on Windows and will be deployed later for macOS and Linux as well.The post Tab Unloading in Firefox 93 appeared first on Mozilla Hacks - the Web developer blog.
