Analysis

Firefox Focus is designed with privacy in mind, offering features like tracker blocking and clearing browsing data. Its privacy notice (S0, effective April 22, 2025) states that "Your browsing data is cleared from your device whenever you close your browser" and that "Focus and Klar process technical and settings data... on your device." However, Mozilla has faced scrutiny for its data practices. In 2024, Mozilla was criticized for sending data, including advertising ID and IP address, to Adjust GmbH from Firefox for Android and iOS to track ad installs without prominent disclosure, leading to the Adjust SDK's removal by August 2024. While the app offers strong privacy controls, the collection of "minimal technical and interaction data" for daily usage pings, retained for 25 months, and past third-party data sharing incidents prevent a fully green rating.
