User Agent Switcher is a straightforward yet powerful Chrome extension designed to change your browser's user-agent string easily. It adds a convenient toolbar button enabling you to toggle between various commonly used user agents, allowing you to mimic different browsers, devices, or search engine spiders. This capability is especially useful for web developers, testers, or users who want to experience websites as they appear on different platforms.

A user agent is a small text sent with each web request that identifies your browser and device, influencing the content websites serve you. With this extension, you can also set specific URLs to always spoof the user agent, streamlining browsing sessions that require consistent spoofing. Note that switching to mobile user agents may sometimes cause issues that require resetting to the default Chrome user agent and clearing cookies for normal operation.

Extension safety

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

User Agent Switcher requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.
