Mozilla Firefox: 126+ Search Categories Telemetry

This detection was added in Anti-Beacon 6.7.

Anti-Beacon treats this as telemetry because Mozilla introduced Firefox search-result-page categorization telemetry in Firefox 126. Mozilla’s Firefox 126 release notes say: “Telemetry was added to create an aggregate count of searches by category” (Firefox 126 Release Notes). Mozilla describes the categories as high-level content types and says the data is collected using OHTTP to remove IP addresses as potentially identifying metadata.

Anti-Beacon disables Firefox search category telemetry. This does not claim to block all Firefox search telemetry; it targets the Firefox 126+ feature that counts searches by category.
