Browser & Navigator

Configure how your browser profile reports its version, OS, screen, timezone, fonts, and media devices.

These settings control how websites identify your browser and device. When modifying them, focus on consistency. Your browser version, operating system, screen characteristics, timezone, fonts, and media devices should describe the same device and environment.

User agent

The user agent identifies the browser and version reported to websites.

Option	Description
Always use latest Chrome user agent	Reports the newest Chrome version regardless of the browser engine the profile runs on.
Match browser user agent	Reports the version that matches the underlying browser engine.
Use specific version	Lets you specify an exact Chrome version.

Leave this on the default unless you aim to match an existing account's history, an older browser for testing, or a fingerprint that should stay fixed over time.

Timezone

Timezone controls the timezone reported by the browser profile.

Setting	Description
Fill timezone based on IP	Automatically sets the timezone based on the profile's IP location.
Manual timezone	Lets you specify a timezone manually.

If you specify a timezone manually, we recommend matching it to the profile's location and IP address. A mismatch here is an easy signal for sites to flag.

Navigator

Navigator settings control browser attributes such as platform, screen resolution, width, and height.

Setting	Description
Platform	Controls the operating system reported by the browser.
Resolution	Controls the screen resolution reported to websites.
Width	Controls the reported screen width.
Height	Controls the reported screen height.

These values should align with each other and with the operating system configured for the profile. For example, a profile configured as macOS should report platform and screen characteristics typical of a Mac device, not a mix of values associated with different operating systems.

Media devices

Media device settings control how many cameras, microphones, and speakers the profile reports to websites.

Setting	Description
Mask media devices	Reports generated media device information instead of your real hardware.
Video input count	Controls the number of cameras reported to websites.
Audio input count	Controls the number of microphones reported to websites.
Audio output count	Controls the number of speakers or audio output devices reported to websites.

Fonts

Fonts are commonly used as part of browser fingerprinting.

Setting	Description
Enable font list masking	Prevents websites from seeing your real installed fonts.
Enable Unicode	Helps protect against Unicode-based font fingerprinting techniques.
Randomize fonts	Generates a different font set for the profile.

If you randomize fonts, pick a value once and stick with it across sessions. A font list that keeps changing doesn't resemble a real device, it signals that something is being spoofed, giving trackers a unique pattern to identify you by. That's the opposite of what randomization is meant to achieve.
