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.

It is very helpfull BUT i can not set custom version of fake browser so I can not use service with existed presets due to outdated version browser it says.

Brickstin (JenixJuno)2024年6月25日

Recent updates to this extension has completely prevented Facebook.com from functioning. This extension is completely useless now............It has broken Facebook entirely.. Worked great while it lasted.

Bill Diavastis (Ironhead HD)2024年6月24日

Does what it's supposed to do, not to complete perfection, but i think it's deserving of a 5 star rating.

K Samsonov2024年6月20日

Hello, please update the user-agent to the new ones! Already, a long time ago, all browsers, very much updated! Good luck and happiness to you)

Maxwell Wilson2024年6月13日

Nice, but I can't get it to automatically work on newly opened windows (even if the main / host window has it enabled)

AI product read

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.
