Each Firefox download has a unique identifier (ghacks.net)

Article summary

Mozilla's Firefox browser includes a unique identifier in its installer, which is submitted to Mozilla on installation and first run. This identifier is used to link downloads to installations and first runs, allowing Mozilla to track downloading and installation trends. Users can avoid this identifier by downloading the Firefox installer from Mozilla's HTTPS repository or from third-party download sites. The feature is powered by Telemetry in Firefox and applies to all Firefox channels.

What commenters say

• The inclusion of a unique identifier in the Firefox installer is a violation of user privacy and trust.
• The identifier is necessary for Mozilla to track and understand its user base and improve the browser.
• Alternative browsers, such as those based on Firefox but without the identifier, are available and may be more appealing to privacy-conscious users.
• The identifier is not a significant concern compared to other browsers, such as Chrome, which have more invasive tracking practices.
• Mozilla's decision to include the identifier may be driven by its funding model, which relies heavily on Google.
• Users can take steps to avoid the identifier, such as downloading the installer from alternative sources or using a different browser.
