Firefox Browser Fingerprint and Privacy Tests

Compare Canvas, WebGL and storage signals under Firefox tracking-protection settings. Understand restricted APIs and how to interpret test results.

Tracking protection and page signals

Firefox Enhanced Tracking Protection can restrict tracking content. That differs from API access on this page: successful drawing here does not establish that a tracking script on another site will run.

Compare normal and private windows

Run Canvas, WebGL and privacy checks in both modes, recording read failures and parameter differences. A protected renderer means limited information, not a faulty GPU. Do not infer the protection mode from one hash alone.

Compare browsers with care

Chromium-specific runtime rules do not apply to Firefox. Missing Client Hints are not evidence of version spoofing. Cross-browser differences may arise from rendering implementations, API support or policy, not just hardware.

Browser Privacy Check

Check browser privacy signals including storage, permissions, Canvas, WebGL and language. Understand fingerprint exposure and the limits of each check.

Canvas Fingerprint Test

Generate a Canvas fingerprint with SHA-256 and compare two renders. See how fonts, graphics rendering and privacy protections can affect the result.

WebGL Fingerprint Test

Inspect your WebGL vendor, renderer, shading language, extension count and texture limit. Generate a hash of the graphics capabilities exposed by your browser.
