Starting November 3, 2025, Mozilla requires all new Firefox extensions to clearly specify what user data they collect or transmit. This information will be shown during installation — on the extension’s page and in browser settings.
The rule applies only to new extensions for now, but Mozilla plans to expand it to all existing ones by mid-2026.
Developers must list data types in the manifest.json file. If no data is collected, that must be explicitly stated. Extensions without this disclosure won’t be published on addons.mozilla.org..
Mozilla offers a clear taxonomy: data is categorized as personal (e.g., name, email, location, search history) or technical (e.g., browser settings, error reports, interface interactions). Some types require explicit consent; others may be enabled by default.
If an extension requests access to sensitive data — such as medical or financial information — users must confirm consent before installation. Otherwise, the extension won’t install.
For technical and behavioral data (e.g., clicks, scrolls, preferences), users can enable or disable collection after installation via Firefox settings.
Extensions that don’t use the built-in consent system but support older Firefox versions must offer users a clear way to manage data collection immediately after installation.
Mozilla has also introduced an API that allows extensions to request additional data consent programmatically — via a separate popup with an opt-out option.
These changes make Firefox one of the most transparent browsers in terms of privacy. Users gain more control, and developers get clear, enforceable rules.
For Chrome, Edge, and other browser users, Mozilla’s approach sets a benchmark for ethical data practices without compromising functionality.
