Overview

By default, Firefox collects telemetry data ¹. This data comprises two main categories: interaction data and technical data ¹.

Interaction data includes metrics such as the number of open tabs and windows, the number of webpages visited, the number and type of installed Firefox Add-ons, session length, and interactions with features offered by Mozilla or third parties. These features may include Firefox search features and search partner referrals ¹.

Technical data provides information about your Firefox version and language, device operating system and hardware configuration, memory, basic crash and error information, as well as the outcome of automated processes like updates and safe browsing ¹.

Note that Firefox logs your personally identifiable IP address ¹.
