--bot-performance-timing: Browser Timing Signals and Fingerprinting
Understand BotBrowser's --bot-performance-timing basic and advanced modes, the Performance Timing APIs they affect, and the limits of proxy and anti-bot cross-checks.
Guides, research, and practical insight for privacy-first browser operations, cross-platform consistency, and BotBrowser deployment.
Start with anti-tracking fundamentals, cross-platform consistency, deployment at scale, or product comparisons.
The fastest way to understand how BotBrowser approaches privacy protection, consistent profiles, and scaled browser workloads.
The Knowledge Hub is for education, comparisons, and commentary. The docs center is for setup, reference, validation, and responsible-use material.

Diagnose Playwright proxy routing, context exclusions and SOCKS5 authentication, then separate two real exit addresses from unchanged browser profile signals.
Fix a Playwright strict mode violation by inspecting duplicate matches, narrowing the intended component and verifying the result. Includes a runnable failure fixture.
Generate Puppeteer PDFs with explicit page settings, print CSS, reliable page breaks, and a practical checklist for missing Chinese glyphs.
Diagnose Puppeteer proxy authentication and SOCKS5 failures, then compare two authorized exits against the same profile, timezone, language and canvas output.
Compare Rebrowser patches, original Playwright and a declared browser profile on one owned page. Separate library behavior, rendering observations and proxy routing.
Fix Selenium element not interactable by checking the command, hidden duplicates, frame, control state and click obstruction. Includes a local Python fixture.
Diagnose Selenium shadow DOM lookup failures with a local Python fixture: document boundaries, nested roots, closed roots and component replacement.
Separate which ad-capture differences come from egress region, which from the language list, and which come from neither, then record the alignment per capture.
The common and targeted levels inspect different things, labels let one rule feed the next, and a block reads nothing like a challenge. One measured 403 shows the difference.
Learn how collection methods, sampling, device splits, and denominators limit what browser usage reports can show.
A managed browser hands you a session over CDP. What it does not hand you is a stable browser identity. Here is the boundary, with the documented limits.
