There is now a special page in the Firefox browser where users can see what telemetry data Mozilla is collecting from their browser. From a report: Accessible by typing about:telemetry in the browser’s URL address bar, this new section is a recent addition to Firefox. The page shows deeply technical information about browser settings, installed add-ons, OS/hardware information, browser session details, and running processes. The information is what you’d expect a software vendor to collect about users in order to fix bugs and keep a statistical track of its userbase. A Firefox engineer told ZDNet the page was primarily created for selfish reasons, in order to help engineers debug Firefox test installs. However, it was allowed to ship to the stable branch also as a PR move, to put users’ minds at ease about what type of data the browser maker collects from its users.
