Chrome protection against malicious websites.
It is technology embedded in Chrome, helps to protect users from malicious web sites. Its absence can be detected. Safe Browsing
Chrome feature variations.
It allows to add or remove browser features for part of users. If it is missing, may be detected. Variations
Enable Chrome components in browser profiles.
Enable Chrome components. Increase profile size, but its absence can be detected.
Browser settings apply to the whole script. Use “Browser Settings” for an individual thread. Browser extensions are also set through that action.
Fingerprint detection
Detect fingerprint collection by websites.
Canvas rendering and noise behavior.
Canvas is html element with graphics like: shapes, images, text, etc. Different browsers and operation systems render canvas content slightly different. These differences may be exploited by sites to identify you among other users. BAS allows you protect you by disabling canvas or add custom noise to canvas content.
Custom noise for debugging.
Custom noise for debugging. This setting is for debugging purposes only. Use FingerprintSwitcher for normal setup. FingerprintSwitcher
WebGL rendering and noise behavior.
WebGl also may identify you among other users in pretty same ways as canvas.

Leave empty to use the real value.
WebGL vendor can expose your real hardware through javascript, so it is good idea to change it. Empty string will leave your real settings. This setting is for debugging purposes only, the proper way to set is using FingerprintSwitcher. FingerprintSwitcher

Audio fingerprint behavior.
Site may identify user by generating sound and reading it as a data. Different browsers and operating systems will do that operation with slightly different results. BAS allows to protect you by disallowing browser to obtain sound data or by adding custom noise to result.

Report fingerprint collection by websites.
FingerprintDetector addon helps to check if site that is opened with BAS uses browser fingerprint techniques to identify you among other users. This includes canvas, audio fingerprinting, font enumeration and many other. You will get detailed report for each fingerprinting activity as a result of its work. This tool can be useful if you want to check why your bot is being banned.
Use the FingerprintSwitcher module to apply a browser fingerprint to each thread.
Network & input
WebRTC and QUIC.
WebRTC may expose your real IP through a proxy.
WebRTC may expose your real IP through a proxy.
One IP address per line. For debugging only.
Replace ips exposed by WebRTC with values from the field above. Each line of that field must contain single ip. This setting is for debugging purposes only, the proper way to set is using 'Proxy' action.
UDP-based protocol; check proxy support.
Unlike HTTP, QUIC protocol is build on top of UDP. Not all proxies supports UDP. It means that enabling QUIC can cause problems when working with certain proxies. It is recommended to enable this option only if sure, that your proxy supports it. Disabled by default.

Reuse common profile files when starting threads.
Creating profile is hard drive intensive operation. In order to do that browser needs to initialize each file located in profile folder. This option allows to copy common files rather than creating them every time. Note that profiles are created implicitly each time new thread is started.
Restart the browser process for each thread.
Restart the browser process for each thread.
Maximum browser rendering frequency.
FPS
Maximum times browser content can be rendered per one second. The lower this value, the lower the CPU usage will be. Setting it too low may affect site operability. Reducing it below 30 may lead to unpredictable consequences. Minimum value is 10.
