Configure Fingerprints and Common Settings

When creating or editing a browser profile, switch to Advanced Configuration to access Common Settings, Fingerprint Settings, and other options. The Advanced Configuration tab on the batch creation page provides the same settings.

Before configuring a profile, identify the proxy location, operating system, and target website requirements it will actually use. The Profile Check panel on the right evaluates the form in real time, but it only identifies obvious conflicts and cannot replace testing on the target website.

Configure Common Settings

Expand Common Settings and enable the options required by your workflow.

Common browser profile settings

Setting	Behavior when enabled	Considerations
Block images	The browser no longer loads images from webpages	May affect pages that use image-based buttons, CAPTCHAs, or product images
Disable video autoplay	Videos play only after user interaction	Some nonstandard video formats may not be blocked
Mute websites	Webpages in the profile remain muted	Does not stop media from continuing to play
Disable translation prompts	The browser no longer offers to translate webpages	Leave disabled if you need browser translation
Disable save-password prompts	The browser no longer asks to save login passwords	Does not remove passwords that are already saved
Disable web notifications	Websites cannot request notification permission or send notifications	Business pages that rely on notifications may no longer alert you
Block clipboard reads	Websites cannot read the system clipboard	Users can generally still paste content manually
Stop launch when the network is unavailable	Cancels the launch if the network or proxy test fails	Recommended for profiles that require a fixed network egress
Stop launch when the IP changes	Cancels the launch if the egress IP differs from the last successful launch	A comparison is available only after the first successful launch
Stop launch when the IP country/region changes	Cancels the launch if the country or region differs from the last successful launch	Recommended when the egress location must remain stable

Configure Location and Regional Parameters

Expand Fingerprint Settings and configure proxy-related parameters first.

Parameter	Modes	Description
WebRTC	Real, IP-based	IP-based mode derives WebRTC information from the current proxy egress to reduce network inconsistencies
Time zone	Default, IP-based, Custom	Custom mode also requires a specific time zone
Geolocation	Real, IP-based, Custom	Custom mode requires longitude and latitude
Language	Default, IP-based, Custom	Custom mode requires a browser language

The proxy location, time zone, geolocation, and language should normally form a reasonable, consistent combination. If your workflow requires fixed values, document the reason and validate them in a test profile.

Configure Display and Hardware Parameters

Continue down the page to configure the display and hardware information presented to websites.

Parameter	Modes or values
Screen resolution	Real, preset, random, or custom width and height
Fonts	System default, random, or a custom font list
Hardware noise	Enable or disable noise separately for Canvas, WebGL, AudioContext, and ClientRects
WebGL	Use real information or provide a custom WebGL vendor and renderer
RAM	Real, custom, or random
CPU	Real, custom, or random
Do Not Track	Default, enabled, or disabled
Port scan protection	Enabled, disabled, or partially allowed; partially allowed mode requires a port list
Hardware acceleration	Default, enabled, or disabled
Battery information	Real or random
Media devices	Default, random, or custom microphone, speaker, and camera counts
Launch arguments	Enter URLs to open or browser launch arguments; separate multiple values with an ASCII semicolon ; and do not add a trailing semicolon

Browser profile fingerprint settings

When customizing WebGL information, check the selected operating system and browser engine together. Avoid vendor and renderer combinations that clearly do not belong to that system.

Review the Profile Check

The Profile Check panel displays a score from 0 to 100, a status of Good, Attention, or Risk, and up to five current issues. It evaluates whether:

• A complete, working proxy is configured.
• WebRTC, time zone, geolocation, and language are consistent with the proxy egress.
• The operating system matches the User-Agent.
• WebGL information matches the operating system.
• Resolution, fonts, hardware noise, and port scan protection use the intended strategy.

Profile check and fingerprint summary

Proxy test results are included in the profile check. If a custom proxy test fails, follow Proxy Test Fails. If the Proxy API cannot fetch a proxy, see Proxy API Cannot Fetch a Proxy. After correcting the network configuration, address any remaining fingerprint warnings.

Important

The profile check is a local assessment based on the current configuration. Its results are for reference only.

Generate a Random Fingerprint

The Primary Fingerprint Parameters card provides Generate New Fingerprint. This action updates selected noise parameters in the current form and is useful for generating test configurations. Before submitting, review the summary and profile check to ensure the generated result meets your requirements.

Save and Validate

1. Resolve any validation errors in the form.
2. Confirm that the proxy, operating system, User-Agent, and regional settings are consistent.
3. For a new profile, select Create Profile or Create and Launch; when editing, select Save Profile or Save and Launch.
4. Use a test website to validate language, time zone, media permissions, and page functionality.

Avoid frequently changing the fingerprint of a profile that has been used for an extended period. If a change is necessary, record the original configuration and validate compatibility in a test profile first.

Next Steps

• Create and Edit a Browser Profile: Review basic information, proxy options, and submission actions.
• Create Browser Profiles in Bulk: Apply a shared configuration to several new profiles.
• Launch and Maintain Browser Profiles: Launch profiles and manage cache, cookies, and accounts.
