Browser Fingerprint FAQ
What is a fingerprint?
Sites collect screen size, OS, browser version, fonts, Canvas/WebGL, timezone, language, etc. to recognize returning visitors.
Why change it?
- Isolate multi-account sessions
- Lower linkage risk
- Match a target region/device profile
Virtual Browser randomizes and isolates fingerprints per profile.
Change fingerprint settings
- Open a profile → Settings → fingerprint tab
- Adjust resolution, OS/UA, language, timezone
- Enable Canvas / WebGL / Audio protections as needed
- Save and relaunch the profile
Settings not applied
- Confirm save succeeded
- Full restart of the profile (not just a tab)
- Avoid conflicting manual overrides vs IP-auto locale
- Some sites use server-side checks beyond fingerprint
Pick a realistic profile

| EU social | en-GB or local language, matching EU proxy |
