During the course of this reporting period, Mozilla continued its efforts to protect the security and privacy of our users through public policy. In the European Union, we ramped up our work on the eIDAS legislation, which threatens web security by placing a ceiling on the standards for web certificates. This included amplifying our public campaign to drive awareness of the risks posed by the issue, organizing an event with a Member of European Parliament and our CSO, briefing the US National Institute of Standards and Technology (NIST) delegation, conducting meetings with members of the European Council, Parliament and Commission, and publishing a report on the negative impact of the law on Europe’s cybersecurity. After some positive developments in the Parliament vote, we are currently engaging with EU policymakers during the interinstitutional negotiations to ensure a net positive outcome for web security. We also organized a panel at the Computers, Privacy and Data Protection (CPDP) conference on privacy preserving advertising. We also published our position paper on the Cyber Resilience Act (CRA) and are engaged in conversations to protect the interests of the open source community.

In the United Kingdom, we continued our work on privacy preserving advertising and mitigating online tracking via conversations with the Competition and Markets Authority (CMA). We intend to expand our policy engagements in the United Kingdom in the coming months.

In the United States, we testified at a congressional hearing in DC on data brokers, spoke at an event organized by National Academies of Sciences, Engineering, and Medicine on children privacy, held meetings with the FTC and Congressional Staffers on privacy and advertising, and submitted comments to the US National Telecommunications Information Administration (NTIA)’s request on the intersection of privacy, equity, and civil rights in commercial data collection practices.

Globally, we joined the Steering Committee of the Global Encryption Coalition to defend encryption in the jurisdictions where it is most at-risk, including India. We also worked with local think tanks on the drawbacks present in the latest version of India’s data protection law. We also spoke on a panel at RightsCon 2023 on how privacy and security might look in the federated social media systems with a global perspective. In Kenya, we briefed the Parliament’s Committee on Communication, Information and Innovation on privacy and the importance of implementing Kenya’s data protection law.
