Browser Profiles

What is a profile?

A profile is an isolated browser session with its own:

• Cookies and session storage
• Hardware fingerprint (User-Agent, canvas, WebGL, fonts, screen resolution)
• Proxy assignment (optional)
• Browser engine selection

Profiles persist across runs. An AI agent that logs into a site in run #1 will still be logged in for run #2 using the same profile.

Creating a profile

1. Go to Profiles in the sidebar.
2. Click New Profile.
3. Configure:
   • Name — descriptive label (e.g. amazon-buyer-us)
   • Browser engine — zendriver (recommended) or patchright
   • Proxy — optional; select from the Proxies list
   • Fingerprint — auto-generated (recommended) or manual override
4. Click Create. The profile directory is created at startup on first use.

Starting and stopping a browser

• Click Launch on a profile card to open the browser in the background.
• Click Stop to close the browser and flush storage.
• A running profile shows a green indicator and the number of active runs.

Fingerprint management

Fantommind auto-generates a randomised but self-consistent fingerprint for each profile:

• User-Agent matches the platform and Chrome version
• Canvas noise applied consistently (same seed per profile)
• WebGL vendor/renderer spoofed to match the UA
• Screen resolution within a plausible range

To reset a fingerprint: Profile detail → Fingerprint → Regenerate. This generates a new consistent set. Existing cookies and storage are preserved.

Proxies

Assign a proxy per profile in Settings → Proxies → Add Proxy:

Field	Description
Label	Friendly name
Protocol	http, socks5
Host	IP or hostname
Port	Proxy port
Username / Password	Optional auth

Proxies are tested on assignment. A failed test shows a warning but does not block saving.

Bulk operations

• Select all → Delete removes profiles and their browser data directories.
• Export (planned v1.1) — export profile cookies as JSON for backup.
