Browser Info Detector - Identify Your Browser & System
Instantly detect your web browser name, version, operating system, language settings, and user agent string. Essential for troubleshooting website compatibility issues, reporting bugs, verifying browser settings, and understanding your browsing environment. Free browser fingerprinting and system information tool.
What Information Does This Tool Detect?
Browser Name & Version
Identifies Chrome, Firefox, Safari, Edge, Opera, or other browsers with version numbers. Helps determine feature compatibility and explain website behavior differences.
Operating System
Detects Windows, macOS, Linux, Android, iOS, or other OS. Important for OS-specific bugs and platform-dependent features.
User Agent String
Complete UA string sent to websites. Contains browser, OS, device, and rendering engine details in encoded format. Used by developers for debugging.
Language & Region Settings
Browser's configured language preference (e.g., en-US, es-ES, fr-FR). Affects default content language on websites.
Cookies Enabled
Indicates whether browser accepts cookies. Critical for website functionality since many sites require cookies for login and personalization.
Why Check Browser Information?
Troubleshooting Website Issues
When reporting bugs to support teams, they'll ask "what browser are you using?" This tool provides exact details to share, ensuring faster problem resolution.
Compatibility Testing
Web developers test sites across browsers. Knowing your browser version helps developers reproduce issues and verify fixes work in your environment.
Security & Privacy
Understanding what information browsers expose helps privacy-conscious users evaluate their browser fingerprint and tracking exposure.
Feature Support
Modern web features (WebGL, Service Workers, WebAssembly) require specific browser versions. Knowing your version helps determine if features will work.
đ Example: Bug Report
Complete browser information for support ticket:
- Browser: Chrome
- Operating System: Windows
- Language: en-US
- Cookies: Enabled
- User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36...
Support can now reproduce issue in identical environment.
Understanding User Agent Strings
UA String Format
User agents follow pattern: `Mozilla/5.0 (Platform) Engine/Version Browser/Version`
Example breakdown:
- Mozilla/5.0: Historical compatibility token (all browsers claim Mozilla)
- (Windows NT 10.0; Win64; x64): OS and architecture
- AppleWebKit/537.36: Rendering engine
- Chrome/120.0.0.0: Browser name and version
Why "Mozilla" in All Browsers?
Historical quirk: early websites checked for "Mozilla" (Netscape browser) to serve advanced features. All browsers now claim "Mozilla/5.0" for compatibility, even though Netscape defunct since 2008.
User Agent Reduction
Modern browsers (Chrome, Edge) reducing UA detail to limit fingerprinting. Future UAs will be more generic, providing less specific version/OS information.
Major Browsers Comparison
Google Chrome
Engine: Chromium (Blink + V8 JavaScript)
Market Share: ~65% global (desktop + mobile)
Strengths: Fast performance, robust dev tools, widest extension library
Weaknesses: RAM hungry, privacy concerns
Mozilla Firefox
Engine: Gecko + SpiderMonkey
Market Share: ~3% global
Strengths: Privacy-focused, open source, customizable
Weaknesses: Smaller extension ecosystem, declining market share
Apple Safari
Engine: WebKit + JavaScriptCore
Market Share: ~20% global (strong on mobile)
Strengths: Energy efficient on Mac/iOS, deep Apple integration
Weaknesses: Slower feature adoption, macOS/iOS only
Microsoft Edge
Engine: Chromium (switched from EdgeHTML in 2020)
Market Share: ~5% global
Strengths: Windows integration, built on Chrome foundation
Weaknesses: Perceived as "bundled" with Windows
Browser Compatibility Issues
CSS Rendering Differences
Same CSS may display differently across browsers due to default styles and rendering quirks. Test critical pages in Chrome, Firefox, and Safari.
JavaScript API Support
Newer APIs (WebGPU, File System Access) available only in specific browsers. Check browser compatibility on MDN or caniuse.com before using.
Mobile vs Desktop Browsers
Mobile browsers often limit features for performance. Desktop-centric sites may break on mobile. Always test responsive design on actual devices.
Privacy & Browser Fingerprinting
What is Browser Fingerprinting?
Technique combining browser info, screen resolution, installed fonts, timezone, language, and plugins to create unique "fingerprint" tracking users without cookies.
Reducing Fingerprint Uniqueness
- Use privacy-focused browsers (Firefox with resistFingerprinting, Brave, Tor)
- Disable JavaScript on sensitive sites
- Use VPN to mask IP/location
- Clear cookies regularly
- Use incognito/private browsing for sensitive activities
Do Not Track (DNT)
Browser setting requesting sites not track you. Unfortunately, DNT is voluntary and widely ignored. Ineffective for privacy protection.
Troubleshooting Browser Issues
Clear Cache & Cookies
Fix loading issues, outdated content, login problems:
- Chrome: Settings â Privacy â Clear browsing data
- Firefox: Options â Privacy & Security â Clear Data
- Safari: Preferences â Privacy â Manage Website Data
Disable Extensions
Extensions can break websites. Test in incognito/private mode (extensions disabled by default) to identify extension conflicts.
Update Browser
Outdated browsers cause compatibility issues. Enable automatic updates:
- Chrome: Auto-updates by default
- Firefox: Options â General â Firefox Updates
- Edge: Settings â About Microsoft Edge
Reset Browser Settings
Nuclear option for persistent issues. Resets to factory defaults, removing extensions and custom settings. Backup bookmarks first.
Frequently Asked Questions
Can I change my user agent string?
Yes, using browser extensions or developer tools. Developers use this to test sites as different browsers. However, changing UA can break sites expecting your actual browser.
Why does my browser show as "Unknown"?
Tool uses simple detection - uncommon browsers (Vivaldi, Brave, older versions) may show as "Unknown" despite working fine. Check full User Agent string for details.
Is browser fingerprinting illegal?
Legal in most jurisdictions but regulated under GDPR (Europe) and similar privacy laws. Sites must disclose tracking methods in privacy policies.
Which browser is most secure?
All major browsers (Chrome, Firefox, Safari, Edge) provide strong security when updated. Firefox/Brave offer better privacy. Use case matters more than browser choice.
Do I need to enable cookies?
Most websites require cookies for login, shopping carts, and personalization. Blocking all cookies breaks functionality on many sites. Use selective blocking instead.
What's the difference between 32-bit and 64-bit browsers?
64-bit browsers handle larger memory, improving performance on sites using lots of tabs/memory. All modern systems should use 64-bit. Check: type `chrome://version` in Chrome address bar.
