Company Values

Our culture ensures our future

Our September 2020 employee survey confirms respect for one another and an emphasis on learning and innovation are what will ensure our future.

Because sometimes we zoom

Since March of 2020, like so many of our peers, we closed our offices and asked just over ½ of our employees, for their safety, to head home to work (the other ½ was already there). And we are all doing the best we can.

Diversity and Inclusion at Mozilla

We’ve made some progress that we’re proud of, and we have a lot more work to do.

Your career growth is part of our mission

Serving 300+ million people means our small team has a mighty mandate. Add a culture of exploration and mentorship, and there is always a new way to learn and grow here.

Truly “mission-driven”

Being wholly-owned by the non-profit Mozilla Foundation means we can focus on the real needs of people, rather than a bottom line.

The web the way it should be

Join a global community of employees, collaborators, activists, and advocates fighting to keep the internet healthy for generations.

Beyond the browser

While our Firefox family of products works to keep everyone safer and smarter online, our Mozilla initiatives focus on shaping the future of the internet.
