    In 2020, Mozilla advocated that Facebook and Twitter “unfck the internet” by turning off its group recommendations feature on Facebook and the trending topics feature on Twitter to stop the spread of what it called “election misinformation.” 7 8 Also in 2020, Mozilla Foundation supported Google subsidiary video platform YouTube’s decision to censor what it identified as “harmful content” and the legally vague concept of misinformation. 9

    Mozilla Foundation has distributed $22 million in award funds since 2015 and supported more than 200 fellows. This funding has supported organizations and individuals in 46 countries across six continents. 10 The Foundation’s funding partners include Omidyar Network, Craig Newmark Foundation, Andrew W.

    History and Leadership

    Mozilla was originally founded as an open-source technology project in 1998. 6 The Mozilla Foundation was officially established in July 2003 and consists of two wholly owned for-profit subsidiaries, the Mozilla Corporation and MZLA Technologies Corporation. 11 In 2004, the Mozilla Foundation was given tax-exempt status from the Internal Revenue Service (IRS). 12

    In 2005, Mozilla Corporation was established as a wholly owned taxable subsidiary that serves the nonprofit, public benefit goals of the Mozilla Foundation. 13 The Mozilla Foundation is headquartered in San Francisco, California, and has global operations in Australia, Canada, China, New Zealand, the Netherlands, Germany, France, the United Kingdom, and other European countries. 11

    Mark Surman is the executive director 14 and president of the Mozilla Foundation. 15 16 In a webinar hosted by left-leaning philanthropic consulting company Arabella Advisors, Surman said that Mozilla affirms that working from a left-wing intersectional perspective that includes critical race theory-influenced concepts such as racial justice and environmental justice is important to shape future technological developments. He also identified working with labor interests as an important use-case for technology in the future. 17

    Activities and Funding

    Mozilla Foundation is a technology-focused nonprofit that wholly owns the Mozilla Corporation 4 and the MZLA Technologies Corporation. 1 2 The Mozilla Foundation developed the Firefox Web Browser in 2004. 4 18 As of 2022, Mozilla Corporation has more than $1 billion in cash reserves and is paid by Google to be the default search engine on the Firefox home page. 19 11

    The Mozilla Foundation claims that its role is to ensure the internet remains a force for good. 6 In October 2020, Mozilla advocated that Facebook and Twitter “unfck the internet” by turning off its group recommendations feature on Facebook and the trending topics feature on Twitter to stop the spread of what it called “election misinformation” prior to the 2020 Presidential election. 7 8 Also in 2020, Mozilla Foundation supported Google subsidiary video platform YouTube’s decision to censor what it identified as “harmful content” and misinformation. 9

    The foundation has also released a pledge for the healthy internet, 20 conducts what it calls artificial intelligence algorithmic audits, 21 supports the development of “trustworthy artificial intelligence,” 22 and conducts other advocacy work. 23

    In 2020, Mozilla Foundation tracked platform changes on social media platforms Facebook, Facebook image-based subsidiary Instagram, Google, Google video subsidiary YouTube, Twitter, and Chinese-owned TikTok regarding the ambiguous concepts of disinformation, misinformation, and other concepts. 24 That same year, Mozilla released a white paper on creating what it calls trustworthy artificial intelligence. The report addresses the legally undefined terms of misinformation and disinformation in its “safety and security” section and call for the regulation and enforcement of artificial intelligence systems and regulations. 25

    In 2021, Mozilla Foundation Senior Advisor Alan Davidson was nominated by the Biden administration and confirmed by the U.S. Senate to lead the National Telecommunications and Information Administration (NTIA), an agency within the U.S. Department of Commerce. 26 27
