In accordance with the requirements of the enacted law (California Consumer Privacy Act) Mozilla in the upcoming Firefox 72 release, scheduled for January 7, will provide the ability to initiate the deletion of data collected through telemetry from Mozilla's servers and to a specific instance of the browser.
The CCPA grants the right to know what personal data is collected and to whom this data is shared, requires access to this data, as well as the ability to amend, delete, and prohibit the sale of already collected personal data. The CCPA's data protection only applies to California residents, but Mozilla has decided to provide telemetry data deletion tools to all users, regardless of their location.
Data deletion occurs if telemetry collection is disabled in the 'about:preferences#privacy' section ('Firefox Data Collection and Use'). When unchecking the 'Allow Firefox to send technical and interaction data to Mozilla' box, which controls telemetry submission, Mozilla to delete within 30 days all data collected up until the telemetry transmission was refused. Data that remains on Mozilla's servers during telemetry collection includes information about performance, Firefox security, and general metrics, such as the number of open tabs and session duration (information about visited websites and search queries is not transmitted). Full details about the collected data can be viewed on the 'about:telemetry' page.
