Why Mozilla?
Mozilla Corporation is the non-profit-backed technology company that has shaped the internet for the better over the last 25 years. We make pioneering brands like Firefox, the privacy-minded web browser, and Pocket, a service for keeping up with the best content online. Now, with more than 225 million people around the world using our products each month, we’re shaping the next 25 years of technology and helping to reclaim an internet built for people, not companies. Our work focuses on diverse areas including AI, social media, security and more. And we’re doing this while never losing our focus on our core mission – to make the internet better for people.
The Mozilla Corporation is wholly owned by the non-profit 501(c) Mozilla Foundation. This means we aren’t beholden to any shareholders — only to our mission. Along with thousands of volunteer contributors and collaborators all over the world, Mozillians design, build and distribute open-source software that enables people to enjoy the internet on their terms.
About this team and role:
The OS integration team is a cross-disciplinary team in charge of improving and maintaining Firefox on its various supported operating systems. We make sure it is a first-class citizen that integrates well with the desktop and supports new features offered by the operating system. Firefox is a sophisticated cross-platform application, and we deal with the operating system specifics. We work on things like crash reporting, interactions with third party software, sandboxing and hardening techniques, and investigate crashes. We develop close to the machine on low-level topics such as browser performance, security, Inter Process Communication (IPC), memory allocators, and power usage. We also maintain the integration with graphical widget libraries on the various operating systems.
