What to Do If BotRefund Flags Your Browser as a Bot: A Troubleshooting Guide

Why False Positives Happen

BotRefund runs 106 independent checks across browser, network, device, and behavior signals. Each check produces one piece of evidence. The system only labels a visit as a bot when multiple independent signals corroborate the same story. A lone mismatch — such as a privacy extension altering a browser API — is kept as evidence and weighed against the full pattern.

According to BotRefund's detection documentation, "Privacy tools, travel, corporate networks, and unusual devices can produce unexpected behavior for genuine people. BotRefund keeps this signal as evidence — not a verdict — and cross-checks it against independent browser, network, device, and behavior data." This design means a false positive usually stems from a temporary configuration that makes your browser look automated to one or two checks while the rest of your session looks human.

Common Causes of False Positives

• Privacy or security extensions — Ad blockers, script blockers, fingerprinting protectors, and VPN browser extensions often modify or hide standard browser APIs (navigator.webdriver, console methods, canvas behavior). These modifications can trigger the Console Debug Evaluator and similar checks.
• Headless or automation mode — Running Chrome with --headless, --disable-gpu, or via Puppeteer, Playwright, or Selenium leaves detectable traces even in "stealth" configurations.
• Corporate or managed networks — Enterprise proxies, zero-trust agents, and TLS inspection appliances can rewrite headers, inject certificates, or alter timing in ways that mimic automation.
• Unusual device or browser builds — Linux distros with hardened kernels, privacy-focused forks (LibreWolf, hardened Firefox), or mobile desktop-mode browsers may expose non-standard API surfaces.
• Stale browser state — Cached service workers, corrupted IndexedDB, or leftover automation cookies from a previous session can persist and confuse checks.

Step-by-Step Troubleshooting

1. Open a clean private/incognito window. This disables most extensions and clears session storage for that window.
2. Disable all extensions. In Chrome: chrome://extensions/ → toggle off. In Firefox: about:addons → disable. Test again.
3. Clear site data for the domain. DevTools → Application → Storage → Clear site data. Or use the browser's "Clear browsing data" for the last hour, selecting cookies and cached files.
4. Check for headless flags. If you're a developer, ensure you're not launching the browser with automation flags. Run a normal user profile instead of a temporary profile.
5. Run the Console Debug Evaluator. Visit the BotRefund Console Debug Evaluator page and run the check. It will show "Normal user" vs "Bot browser" expectations for the specific signal.
6. Compare results. If the evaluator now shows "Normal user" patterns, the false positive was caused by one of the items above. Re-enable extensions one by one to identify the culprit.
7. Document and whitelist. If a necessary tool (corporate VPN, accessibility extension) triggers the signal, note which check fires. BotRefund's cross-checking means one flagged signal rarely changes the overall verdict, but you can share the specific check name with your security team or BotRefund support.

How BotRefund's Detection Works

Understanding the three-layer architecture helps you see why a single flagged check doesn't equal a bot verdict:

• Independent evidence — Each of the 106 checks adds one objective fact about the visit. The Console Debug Evaluator, for example, looks for a mismatch that a real browsing session does not normally create.
• Cross-checked context — BotRefund tests whether other signals support the same story. A privacy extension might trip the Console Debug Evaluator, but your mouse tremor, scroll behavior, and network latency will still look human.
• AI prediction — The model weighs the complete pattern instead of trusting a raw rule. This is how BotRefund achieves its stated 99% accuracy: "Accuracy comes from corroboration, not one browser tell."

This means troubleshooting a false positive is about making your browser's overall pattern consistent, not about passing every single check in isolation.

Limitations & When This Advice Doesn't Apply

• You're a site owner seeing flagged visitors. This guide is for end users who believe they were incorrectly flagged. Site owners should review the BotRefund dashboard's evidence breakdown and adjust suppression rules if needed.
• Persistent flagging across clean browsers. If multiple clean browsers on different networks still trigger bot verdicts, the issue may be your IP reputation, ISP-level proxy, or device fingerprint. Contact BotRefund support with the specific check names and session IDs.
• Automation developers testing stealth configs. If you're intentionally running headless Chrome for testing, expect flags. Use a dedicated test environment or BotRefund's staging mode if available.
• Mobile app webviews. In-app browsers (Instagram, Facebook, TikTok webviews) often strip APIs and behave differently. These are known to produce anomalous signals and are handled separately in BotRefund's mobile SDK.

Terminology

Console Debug Evaluator

One of BotRefund's 106 checks. It compares browser API behavior against expected norms to spot automation frameworks that patch or hide APIs.

Headless mode

Running a browser without a visible UI, typically for automation (Puppeteer, Playwright, Selenium). Leaves detectable traces in navigator properties and timing.

Cross-checked context

BotRefund's second detection layer: verifying whether multiple independent signals tell the same story before reaching a verdict.

AI prediction

Final layer that weighs the complete pattern of browser, network, device, and behavior evidence instead of relying on any single rule.

False positive

A human visitor incorrectly classified as a bot. In BotRefund's system, this typically requires multiple corroborating anomalies, not just one flagged check.

FAQ

Will clearing cookies log me out of everything?

Clearing site data for the specific domain only affects that site. Use DevTools → Application → Storage → Clear site data to target just the problematic domain.

Which extensions are most likely to cause false positives?

Fingerprinting blockers (CanvasBlocker, Trace), script blockers (NoScript, uMatrix), and privacy suites (Privacy Badger, DuckDuckGo Privacy Essentials) frequently modify navigator properties and console APIs that the Console Debug Evaluator checks.

Can a corporate VPN cause a false positive?

Yes. Enterprise proxies and TLS inspection can alter timing, headers, and certificate chains. BotRefund's network-layer checks may flag this, but your behavior signals (mouse, scroll, typing) usually keep the overall verdict human.

How do I know which specific check flagged me?

If you have access to the BotRefund dashboard (as a site owner), the evidence breakdown lists each check and its result. As an end user, run the Console Debug Evaluator page directly — it shows pass/fail for that specific signal.

Does BotRefund share my browser data with advertisers?

BotRefund's purpose is bot detection and ad-click refund recovery for site owners. The detection runs client-side; signals are sent to BotRefund's prediction engine. Review their privacy policy for data handling details.

What if I need a privacy extension for accessibility?

Run the troubleshooting steps to identify which extension triggers which check. If the extension is essential, note the specific check name (e.g., "Console Debug Evaluator") and share it with your site's admin or BotRefund support. One flagged check rarely changes the verdict due to cross-checking.

How often should I re-test after making changes?

Immediately after each change (disable extension, clear data, exit headless). The Console Debug Evaluator gives instant feedback. Once you see "Normal user" patterns, the false positive is resolved for that session.

How BotRefund can help

BotRefund's detection is built on corroboration: 106 independent checks feed an AI that weighs the full pattern. If you're a site owner, the dashboard shows exactly which checks fired for each visitor, so you can distinguish a privacy-tool false positive from a real bot. If you're an end user, the Console Debug Evaluator lets you test your own browser against the same checks BotRefund uses. The free bot audit installs in about a minute with no credit card, and BotRefund can recover refunds from Google and Meta for bot clicks going back to 2017.
