Hiring · 121 open jobsGeneral information
Mozilla builds internet products focused on privacy. Its products include the Firefox browser, Mozilla VPN, Mozilla Monitor, Firefox Relay, MDN Plus, and the Thunderbird email client. Mozilla is based in San Francisco, California.
Netscape Communications started Mozilla as an open-source project in 1998, after announcing in January that its browser would be free and open source. The Mozilla Foundation became its legal steward in July 2003. Mozilla is a non-profit foundation with a for-profit subsidiary, Mozilla Corporation. It had about 1,000 employees before cutting 25% of its staff, around 250 people, in 2020. That matters: the non-profit structure means Mozilla answers to its mission rather than shareholders, but it still had to cut jobs when money got tight. Mozilla is an H-1B sponsor.1
