Extension-Related Signal Scan
Run a client-side heuristic scan for signals associated with extensions or other injected page behavior. It does not enumerate installed extensions.
Limitations
Browser extension detection is heuristic by design and cannot produce a full extension list.
- Modern browsers restrict direct extension enumeration from normal web pages.
- Signals can be caused by built-in browser features or strict network policies.
- Use this result as educational evidence, not a definitive inventory.
- Absence of signals is not proof of absence — most extensions leave no detectable trace.
How extension fingerprinting works
Extensions can leave subtle traces in page behavior. Even a few unique traces can increase your identifiability.
Signals this demo checks
- •Blocking patterns for ad-like resources and DOM bait elements
- •Injected JavaScript providers from wallet extensions
- •DOM attributes commonly injected by writing assistant extensions
- •Plugin exposure as an additional fingerprinting surface
How to reduce extension fingerprinting risk
Keep only what you need
Remove unused extensions and avoid installing many overlapping tools.
Prefer reputable privacy tools
Use well-maintained extensions with transparent privacy policies.
Review extension permissions
Regularly check host and data permissions, and revoke broad access where possible.
Use separate browser profiles
Separate daily browsing from specialized extension-heavy workflows.
