Disable Firefox telemetry

Overview​

About this category

This category contains privacy scripts for Linux.

These changes use Linux system commands to update your settings.

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.
