Firefox for Android Vulnerability Affects Triggering Principal Calculation

Summary

If a specific sequence of actions is performed when opening a new tab, the triggering principal associated with the new tab may have been incorrect. The triggering principal is used to calculate many values, including the Referer and Sec-* headers, meaning there is the potential for incorrect security checks within the browser in addition to incorrect or misleading information sent to remote websites. This bug only affects Firefox for Android. Other versions of Firefox are unaffected. This vulnerability affects Firefox < 127.
