Advanced User Agent Switcher is a free Chrome extension developed by KodeMuse Software Private Limited. It allows users to easily change their browser user agent string across all websites. With this extension, users have two options to modify their user agent string: they can either use a custom user agent string or choose from a list of pre-defined user agent strings.

Changing the user agent string can be useful for a variety of purposes, such as testing website compatibility with different browsers or accessing websites that are only available to specific user agents. Advanced User Agent Switcher simplifies this process by providing a convenient interface within the Chrome browser.

It's worth noting that this extension does not collect or transmit any personally identifiable information. It also does not track browsing behavior. All necessary information for the functioning of the extension is stored locally on the user's device, ensuring privacy and security.
