How to Reliably Identify Google Chrome Browsers in a Dynamic Web Environment?

Identifying Chrome Browsers with Precision

Determining whether a user's browser is Google Chrome is crucial for tailoring website experiences and ensuring compatibility. The conventional method involved checking the presence of the "window.chrome" property, but recent browser updates have complicated this approach.

A Comprehensive Solution

To address these complexities, a comprehensive JavaScript code has been developed that factors in various browser changes. It checks if the following conditions are met:

• Existence of "window.chrome": Indicates potential use of Chrome.
• vendorName: Ensuring it's "Google Inc." to rule out browsers such as Opera.
• Opacity of Opera: Verifying the absence of "window.opr" to avoid false positives from Opera 30 and later.
• IE Edge Compatibility: Excluding IE Edge by checking for the absence of "Edg" in the user agent.
• iOS Chrome Distinction: Identifying Chrome on iOS devices using the "CriOS" property.
• Google Chrome Brand: Utilizing the "userAgentData.brands" array introduced in Chrome 66 to confirm the browser's identity.
• Non-Firefox Confirmation: Adding an additional check to exclude Firefox browsers.

This code effectively distinguishes Chrome browsers from other browsers, even in the face of evolving browser updates.
