What our analysis found
User Agent Switcher, used by 100,000 people, showed no malicious code in Extension Auditor's review. Its permissions mean it can read and change data on all websites. It comes from a trusted publisher and was last updated in September 2026.
Analyst notes
The extension implements User-Agent switching using declarativeNetRequest and content script injection, which are its core functions. No network exfiltration, tracking, or unauthorized data collection was found in any JavaScript file. The broad permissions are justified for modifying UA on all sites. ML score is low (0.06) and third-party likelihood is 0; the critical risk engine flags are based on permissions, not code behavior.

About this extension
Simplest way to switch between user-agents in your browser!
Read the publisher’s full description
User Agent Switcher is simple, but powerful extension. And much easier to use the Internet, regardless of which browser or operating system you prefer. It adds a toolbar button that you can use to toggle between different commonly used user agent strings. So what’s a User Agent? A user agent is a small text description of your device that is sent with every web request. Websites can detect the browser you’re using and serve different content - this is why iPhone and Android users see special mobile websites when they browse the web. With this chrome extension, you can quickly and easily switch between user-agent strings. Also, you can set up specific URLs that you want to spoof every time. Changing User-Agent allows you to mimic, spoof or fake other browsers, devices or search engine spiders. Note: Sometimes problems may occur after using a mobile user-agent, and won't switch back no matter what you spoof, you will need to switch the user-agent back to Chrome and clear your cookies for the sites to treat the browser normally again!
