Policy Supplement

In the second half of 2024, Mozilla continued its steadfast commitment to protecting user security and privacy through proactive policy engagement in the United States, Europe, and globally. Recognizing the increasing regulatory challenges surrounding encryption, privacy, and online security, we worked to influence key legislative discussions, advocate for privacy-enhancing technologies, and safeguard encryption from threats that could undermine its role in protecting users worldwide.

In the U.S., Mozilla’s policy team engaged with lawmakers at both the federal and state levels. As part of our ongoing efforts to support strong encryption policy and user privacy, we actively participated in discussions surrounding major federal privacy proposals, including testifying a U.S. Senate hearing held by the Commerce, Science, and Transportation Committee titled “The Need to Protect Americans’ Privacy and the AI Accelerant.” Represented by Mozilla’s former Director of Global Product Policy, Udbhav Tiwari, we emphasized the importance of robust privacy protections in an AI-driven landscape. In addition, Mozilla has been heavily engaged in federal policy debates at the intersection of AI and openness. This includes providing submissions to key federal requests for information, including to NTIA, which later affirmed the importance of openness in AI.

With states becoming increasingly active in legislating key technology issues such as AI, encryption, and privacy, Mozilla also extended its advocacy to the state level. In California, we issued a statement supporting the intent behind bill AB 3048, which aimed to require browsers and mobile operating systems to include an opt-out setting—an approach aligned with Mozilla’s support for universal opt-out mechanisms like Global Privacy Control (GPC). Our work at the state level has increasingly included artificial intelligence as well, with Mozilla providing comments on California’s SB 1047.

In Europe, Mozilla continued its engagement with European policymakers following the publication of our policy recommendations for the new EU mandate. We prioritized advocating for stronger online privacy protections and regulations that incentivize the adoption of Privacy-Enhancing Technologies (PETs). Our work also involved direct engagement with the European Commission to ensure that encryption and web security remain intact under the implementation of Article 45 of the eIDAS Regulation. Mozilla is committed to preserving browser-driven cybersecurity standards for website authentication and preventing measures that could weaken encryption.

Globally, as part of our longstanding collaboration with the Global Encryption Coalition (GEC), Mozilla played a central role in advocating for encryption protections in the European policy landscape. We hosted a panel discussion on eIDAS Article 45 at the GEC’s annual Encryption Summit, reinforcing the need for policies that maintain the integrity of web security.

Mozilla continued its global advocacy efforts through the Global Encryption Coalition Steering Committee (GEC SC). As governments worldwide increasingly attempt to regulate encryption in ways that could undermine user security, Mozilla joined GEC SC in opposing legislative measures that threaten encryption’s role in protecting privacy and free expression.

Additionally, Mozilla and GEC members closely monitored and engaged with ongoing discussions surrounding the European Child Sexual Abuse (CSA) Regulation. We released a statement outlining the dangers of mandated scanning for encrypted messaging services, particularly highlighting the security and rights risks associated with client-side scanning, also known as "upload moderation." Meanwhile, in the European Parliament, we supported the MEPs' Pledge in Favor of End-to-End Encryption (E2EE) and released a statement emphasizing the critical importance of encryption as a fundamental safeguard for user privacy and digital security.
