The new Firefox 75, which recently released, brings a new scheduled task to Windows which enables data collection, and the information is submitted to Mozilla once a day.
Mozilla pre-announced change in March 2020, stating that the purpose of this new scheduled task, which is only triggered if the users turn it on, it's to help improve Firefox by “understanding default browser trends”.
Of course, Mozilla says that no personal data is collected, because the company is only interested in “information about the current and previous default settings of the browser, as well as the version running on functional system".
Mozilla guarantees that the data collected can not be associated with any normal profile and as soon as users turn off the telemetry, the service is automatically turned off.
Of course, as mentioned above users can stop the service themselves by simply deleting the scheduled task from their Windows 10.
"Telemetry data collection is one way we can ensure that we can understand the default browser trends in a way that helps us improve Firefox. "We hope to better understand our users and their choices around browser preferences, so we can continue to build a better Firefox," says Mozilla.
If you want to check the information that Mozilla collects from Firefox, you can open the following internal address:
about: telemetry
This page displays information collected and details that have been stored in the past and have already been submitted to Mozilla.
Mozilla states that it will keep the telemetry data for 13 months "only", after all the information is automatically removed. On the other hand, once you turn off telemetry from Firefox, your data is deleted from Mozilla servers within 30 days.
