Commit Access Requirements

By committing to Mozilla repositories - that is, by directly contributing source code, documentation or other data ("Code") to a website or repository operated, controlled or managed by the Mozilla Foundation or its affiliates (a "Mozilla Repository") - you are indicating your agreement to the terms set out below.

For the avoidance of doubt: this document commits you to a set of good behaviours; it is not a copyright assignment.

Treatment of Account

You will receive one or more sets of Mozilla project access credentials, and/or one or more sets of credentials you already have will be given the power to access a Mozilla Repository. You will not allow anyone else to use these credentials to access any Mozilla system. Should You become aware of any such use, You will immediately notify the Mozilla Foundation; until such notice is received You will be presumed to have taken all actions made using Your credentials.

The Mozilla Foundation and their designates will have complete control and discretion over capabilities associated with Your credentials and may change them for any reason at any time. Your name and email address, or a derivative of it, may be attached to your contributions and so be visible worldwide via the Internet.

License Terms

Code committed by you to a Mozilla Repository, whether written by you or a third party, must be governed by the Mozilla Public License 2.0, or another license or set of licenses acceptable to the Mozilla Foundation for the Code in question. Other licenses are not acceptable to the Mozilla Foundation until the Foundation declares them to be acceptable in writing. You will verify that committed Code contains appropriate boilerplate licensing text.

Notices and Knowledge

By contributing Code, You confirm that, to the best of Your knowledge, the Code does not violate the rights of any person or entity.

If You contribute Code on behalf of Your employer, then You confirm that an appropriate representative of that employer has authorized the inclusion of such Code in a Mozilla Repository and that it meets these requirements.

Committing Code Created by Others

You may check in Code to a Mozilla Foundation repository that was not written by You, provided that:

  1. The checkin comment contains information (or references to information) sufficient to identify the author of the Code, the license of the Code, and the third-party public source code repository the code was taken from, if it came from such a repository; and
  2. You make all reasonable and appropriate efforts to ensure that such Code conforms to sections 2 and 3 of this document.
