AMO Policies

Mozilla is committed to ensuring an excellent experience for both our users and developers of add-ons. Please review the policies below before submitting your add-on.

Developer Agreement

This agreement is effective as of June 10, 2019.

Add-on policies

Add-ons extend the core capabilities of Firefox, enabling users to modify and personalize their Web experience. A healthy add-on ecosystem, built on trust, is vital for developers to be successful and users to feel safe making Firefox their own.

For these reasons, Mozilla requires all add-ons to comply with the add-on policies on acceptable practices. The policies are not intended to serve as legal advice, nor are they intended to serve as a comprehensive list of terms to include in your add-on’s privacy policy.
