Overview

Product summary

Review the store description, core capabilities, and common use cases.

Usage example: You can alter your user-agent string to indicate you?re on a mobile device if you prefer seeing mobile versions of sites so they load quicker.

This extension allows you to spoof your browser "user-agent" string to a custom designation, making it impossible for websites to know specific details about your browsing arrangement.

Bitte einmal eine Option einfügen die es erlaubt den UserAgent alle X Sek/Minuten automatisch zu wechseln.

Simply didn't work. Websites weren't fooled for a moment.

This seems to perhaps be the most flexible of the User Agent switcher extensions available, thanks for building it. It does need some work to make it have more up-to-date agents available, or make the user interface more clear to show how to define a new user agent very easily. For example, pasting one into the current extension dropdown is not clear whether it will work properly or overwrite an existing one, or so forth. There should be a "Custom UA String:" label or such to make it clear for readily defining one.

Poorly done, bugs, causes severely high CPU usage only with this extension enabled. Couldn't uninstall fast enough!!! If you're like me and wondering why all of a sudden your browser is hanging and crashing, look no further... This extension is the culprit

Tiện ích rất tốt, có thể giữ tự động giữ nguyên trạng thái useragent trên mọi trang web hoặc trang web chỉ định, và đặc biệt là có thể thay đổi giá trị useragent tùy ý. Mình đang dùng cái này để lừa chatbot Bing AI hoạt động trên Chrome thay vì Edge

User-Agent Switcher and Manager - spoofs/modifies the browser's user-agent string to disguise browser identity from websites

Prevents websites from detecting your real browser, OS, and device through user-agent strings and Client Hints headers. Also useful for developers testing how sites render for different browsers/platforms.

User clicks toolbar popup → browses a large database of real user-agent strings filtered by browser and OS → selects or manually enters a user-agent string → applies to current tab, all tabs, or a specific window. The extension intercepts web requests via declarativeNetRequest and modifies User-Agent headers and navigator object properties to match the spoofed identity. Options page allows configuring blacklist/whitelist domains, custom per-domain rules, protected URL keywords, and Client Hints behavior.

Target users: Web developers testing cross-browser compatibility / Privacy-conscious users wanting to mask browser fingerprint / QA testers verifying mobile/responsive site versions / Users wanting to bypass browser-specific content restrictions

The donate button links to an external page - cannot verify what payment method (if any) is presented on the destination
External CDN fetches to cdn.jsdelivr.net for browser data JSONs are for user-agent database loading, not gated content
The extension includes 417 files, most of which are JSON files containing real user-agent strings for different browsers/OS combinations

Monetization

No paid features detected

No premium features, subscriptions, payment APIs, license gates, or upgrade flows detected. The 'donate' button is voluntary support for development and links to external homepage - it does not gate any features. All keyword matches for 'pro' are false positives matching 'protected' (URL exemption feature), 'productTitle' (navigator.product field), and 'product' (browser engine name like Gecko). No payment platforms (stripe, paypal, etc.) found. The 'license' match is the AGPL license of the bundled ua-parser.js library.

Confidence: 95
Payment platform: --
Source: AI / High
Login required: No
Reason: No login UI, authentication flow, OAuth, or account creation detected. All keyword matches for 'session' are Chrome extension APIs (chrome.storage.session, declarativeNetRequest.updateSessionRules), not user login sessions. The 'account' matches in agent.js (accounts.google.com, accounts.youtube.com) are in a protected-domains list that tells the extension NOT to spoof user-agent on those sites — to avoid breaking their login, not to require login.
