About Firefox Pioneer

Firefox Pioneer is a feature that allows you to opt in to contribute sensitive data that helps us understand the Web, how people interact with it, and how people use their browsers. Participation in Firefox Pioneer is strictly voluntary. Once you’ve opted in, you will have the option to choose which studies to participate in. These studies will collect varying information about your browsing behavior, possibly including what web pages you visit and how you interact with them.

We protect your privacy by ensuring the following:

  • Your individual data will not be shared to the public or sold. Only a small number of researchers will have access to raw data, and that data can only be accessed if it’s relevant to their particular study.
  • A panel of privacy, security, and research experts will review proposed studies to make sure that your privacy is protected and only necessary and appropriate data is collected. Studies not approved will not be shipped.
  • You will be given a random ID that we only use for Firefox Pioneer.
  • Pioneer will not be active in Private Browsing, nor will it collect any cookies, login information, email addresses or form information.
  • The data you submit is encrypted in Firefox and not decrypted until it is on a server that is not connected to the wider internet.

By participating in this group, you will help us to make better decisions on your behalf and shape the future of Firefox!
