Mozilla introduced a push to enhancing privateness for all customers of the Firefox net browser not too long ago. The group started to enable Tracking Protection performance for all new installations with the discharge of Firefox 67.0.1 Stable, and plans to flip the swap for present installations as nicely if settings weren’t modified by customers already.
The new default stage blocks “some” trackers in personal and common shopping home windows, and identified monitoring cookies. The earlier setting blocked some identified trackers in personal home windows solely.
The corporations and people that function these trackers and websites might react to the change, and Mozilla needs to be ready for that.
The group plans to run an experiment in development versions of the Firefox net browser to detect workarounds by these organizations and people.
Mozilla is conscious of the delicate nature of the information and determined that it will want a higher approach to analyze the information that will not probably reveal delicate info.
Firefox Origin Telemetry
Mozilla developed Firefox Origin Telemetry for that particular use case. The element is constructed on high of Prio, a “privacy-preserving information assortment system developed by Stanford Professor Dan Boneh and PhD candidate Henry Corrigan-Gibbs”.
Mozilla needs to accumulate blocklist totals solely.
We will use Firefox Origin Telemetry to accumulate counts of the quantity of websites on which every blocklist rule was energetic, in addition to counts of the quantity of websites on which the principles had been inactive due to one of our compatibility exemptions. By monitoring these statistics over time, we are able to decide how trackers react to our new protections and uncover abuse.
Firefox Origin Telemetry wants to be validated earlier than it might land in launch versions of Firefox. Mozilla plans to run a take a look at beginning with Firefox 69 Nightly.
Prio requires that information is collected by two impartial events and Mozilla plans to meet the requirement in launch versions. For this preliminary take a look at, nevertheless, Mozilla will run each information assortment servers.
The collected information falls throughout the group’s “information assortment insurance policies” for pre-release versions of the Firefox net browser. The take a look at runs on 1% of the Firefox Nightly inhabitants as that’s all that’s required to validate the API.
Firefox Nightly customers who don’t desire to take part in the experiment might disable Firefox’s potential to set up and run research, and to ship technical and interplay information to Mozilla.
Both choices might be configured on the about:preferences#privateness below Firefox Data Collection and Use.

Mozilla is open when it comes to the amassing of Telemetry information whereas corporations like Google do not reveal a lot in any respect when it comes to that and the experiments that they run. The openness places Mozilla in a tough spot as it could be criticized for the selections it makes; Google will not be criticized almost as a lot as it’s normally tight-lipped in all these regards.
