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.

Got this to watch prime streaming in HD on chromebook, tried one other user-agent extention that didn't work after lots of messing around. This worked first time, and I prefer the UI. It is a bit confusing for a second or two, so can understand the other reviews saying they didn't like the UI but I thought it was great, as I said, takes a moment to work it out, but once I had, applied the first windows pre-set, refreshed tab through the UI, HD immediately. Thank you!!

I use this for longtime. Good but at this time this extension is effected to my facebook. When i enable this extension. My facebook keep showing blocking content (Rate limit). So i think extension use facebook token for spamming? I have no idea why. But when i disable and logout/login my facebook is fine. If not logout it still keep showing the error/block message from facebook.

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.
