Best Practices

Practical guidance for multi-account workflows with Virtual Browser: isolation, operations, and risk control.

Multi-account isolation

Rules:

1. One account, one profile — never share profiles between accounts
2. Unique fingerprints — no duplicate fingerprint sets across accounts
3. Unique proxies — avoid reusing the same exit IP across accounts
4. Isolated storage — cookies and local data must not leak between profiles

Naming convention

[Platform]-[Role]-[Purpose]-[Index]
Examples:
- Amazon-Seller-Main-001
- Facebook-Ads-001
- TikTok-Creator-001

Group by platform (Amazon / eBay / Shopify) or by role (content, ads, support, testing).

E-commerce

Amazon (example)

{
  "fingerprint": {
    "screen": { "width": 1920, "height": 1080 },
    "language": "en-US",
    "timezone": "America/New_York"
  },
  "proxy": { "type": "http", "host": "us-proxy.example.com", "port": 8080 }
}

• Stagger logins across shops (5–10 min gaps)
• Avoid identical catalog edits on all shops at once
• Sync inventory/pricing on a schedule

eBay / Shopify

Match fingerprint locale to marketplace region (e.g. en-GB + UK proxy for eBay UK; Mac UA + US West for US Shopify).

Social media

• Separate profiles for personal vs business vs ads
• Natural posting intervals; avoid robotic bursts
• TikTok mobile UA only when the workflow truly needs mobile WebKit

Data collection & automation

{
  "rotation": {
    "strategy": "round_robin",
    "requestsPerEnv": 100,
    "cooldown": 300
  },
  "rate_limiting": {
    "requestsPerMinute": 60,
    "delayBetweenRequests": 1000
  }
}

• Rotate UA and proxies
• Human-like delays
• Isolate test automation from production accounts

Security & privacy

• Strong passwords; encrypt exports
• Rotate fingerprints and proxies periodically
• Clear session/cache when retiring a profile
• Follow platform ToS and local law

Performance

• Cap concurrent profiles for your RAM (see Performance optimization)
• Watch CPU/RAM; restart client after long sessions
• Use batch tools instead of manual repetition

When things go wrong

Symptom	Check
Detection / CAPTCHA	Fingerprint vs IP region; behavior speed
Proxy errors	Credentials, protocol, health
Slowness	Profile count, cache size, disk

See Troubleshooting for step-by-step fixes.

Summary

Consistent isolation, realistic fingerprints, quality proxies, and disciplined operations reduce linkage risk and improve throughput. Review workflows as platforms and detection evolve.
