When you turn sharing off, Firefox will stop sending information about your browser to Mozilla servers. Firefox will send a request to the Mozilla servers to delete the previously submitted information. This request is processed immediately after being successfully received. If the browser does not receive a response that the request was successfully processed (due to lack of internet connectivity, for instance), the browser will continue to send the delete request periodically until it is successfully received.

If you do not turn sharing off, but the browser is no longer sending data (due to being uninstalled or no longer being used), the previously sent data from your browser will be deleted after 180 days.

Even if you choose not to share data with Mozilla, you will still be able to see information about your browser when you go to the Firefox Health Report page, and you can view the comparison data from other browsers that are sharing their data. The comparison data will not be based on the data from your browser since it was not shared with Mozilla.

What data is shared with Mozilla?

The Important Metrics section in the Firefox Health Report has all the data that is shared with Mozilla. To look at the exact data being shared with Mozilla, tap on the see the information we record link under the Important Metrics section.
