Tracking Token Stripper

uBlock Origin

uBlock Origin includes a removeparam feature that supports fine-grained matching and removal of query string parameters. The AdGuard URL Tracking Protection list provides well-maintained coverage for a large number of domains and query string tokens.


Firefox 102 includes built-in removal of tracking query string parameters. In Privacy & Security settings, ensure Enhanced Tracking Protection is set to Strict (required to activate the query string feature). The default set of removed query params is limited, but you can configure your own via the privacy.query_stripping.strip_list pref as a space-separated list.
