Browser environment consistency
Compare browser-visible attributes and repeat available component samples. Distinguish variation, unavailable data and observed differences. Differences alone are not account risk, and raw fingerprints stay out of public reports.
Using and interpreting this tool
Confirm the target and measurement point, then start the checks you need. Results retain sources, observation times and missing-data reasons. Traffic-intensive checks require a separate start.
After changing one setting, start a fresh run and compare A/B snapshots in history. Unknown, unconfigured and inapplicable do not mean passed.
