Auto-Window Agent is a Chrome add-on that automatically sets a custom User-Agent string for seamless web browsing. Designed to enhance website compatibility and provide a consistent browsing experience, this extension operates quietly in the background, requiring no user intervention. It utilizes Chrome's `declarativeNetRequest` API to modify outgoing HTTP and HTTPS requests efficiently, ensuring a stable browsing environment. The fixed User-Agent string it employs is widely compatible, making it particularly useful for web developers and testers who need to simulate different browsing conditions without manual adjustments.

With its lightweight design, Auto-Window Agent consumes minimal resources while maintaining privacy by not collecting or transmitting personal user data. Users can enjoy a predictable web experience across all browsing sessions, accessing content that may otherwise behave unexpectedly based on the default User-Agent. The automatic nature of the extension simplifies the process, allowing users to focus on their online activities without the hassle of manual configurations.
