Tor Browser Complete Guide: Setup, Settings & Security
Everything you need to know about Tor Browser. Installation, optimal security settings, common mistakes to avoid, and advanced configuration tips.
Tor Browser is your gateway to the dark web and enhanced online privacy. This guide covers everything from installation to advanced configuration for maximum security.
What is Tor Browser?
Tor Browser is a modified version of Firefox that routes your internet traffic through the Tor network. This provides:
- Anonymity - Websites can't see your real IP address
- Privacy - Your ISP can't see what sites you visit
- Access - View .onion sites and bypass censorship
- Security - Built-in protections against tracking
Installation Guide
Windows
- Download the .exe installer from torproject.org
- Run the installer and choose your language
- Select installation folder (default is fine)
- Click Install and wait for completion
- Launch from Start menu or desktop shortcut
macOS
- Download the .dmg file from torproject.org
- Open the .dmg file
- Drag Tor Browser to your Applications folder
- First launch: Right-click > Open (to bypass Gatekeeper)
- Allow the app in System Preferences > Security if prompted
Linux
- Download the .tar.xz file from torproject.org
- Extract:
tar -xvf tor-browser-*.tar.xz - Enter the directory:
cd tor-browser_en-US - Run:
./start-tor-browser.desktop
First Connection
When you first open Tor Browser, you'll see the connection screen:
Connect
Use this option if you have unrestricted internet access. Tor will automatically connect to the network.
Configure
Use this if Tor is blocked in your country, you're behind a restrictive firewall, or need to use bridges.
Security Level Settings
Tor Browser has three security levels. Access them by clicking the shield icon next to the URL bar:
| Level | JavaScript | Features Disabled | Best For |
|---|---|---|---|
| Standard | Enabled | None | Trusted sites, full functionality needed |
| Safer | HTTPS only | Some fonts, math symbols, JS on HTTP | General dark web browsing (recommended) |
| Safest | Disabled | JS, some fonts, icons, math, audio/video | High-risk sites, maximum security |
Essential Security Settings
Do These Immediately
- Set security level to "Safer" - Click shield icon > Change
- Don't maximize the window - Window size can fingerprint you
- Keep default settings - Customizations can identify you
- Enable HTTPS-Only Mode - Settings > Privacy & Security
Privacy Settings
Navigate to Settings > Privacy & Security:
- Cookies - Keep "Delete cookies when Tor Browser is closed" enabled
- History - "Never remember history" should be selected
- Permissions - Block location, camera, microphone by default
- Deceptive Content - Keep phishing protection enabled
Common Mistakes to Avoid
Never Do These
- Install browser extensions - They can identify you and leak data
- Maximize the browser window - Reveals your screen resolution
- Download and open files - Can reveal your real IP
- Use Tor for personal accounts - Links your anonymous and real identities
- Enable JavaScript on unknown sites - Use "Safer" or "Safest" mode
- Modify browser settings extensively - Makes you more unique/trackable
Using Bridges
If Tor is blocked in your country, bridges can help you connect:
- On the connection screen, click "Configure"
- Select "Tor is censored in my country"
- Choose "Select a built-in bridge" or request one
- Built-in options: obfs4, meek-azure, snowflake
Which bridge to use:
- obfs4 - Good general-purpose option
- meek-azure - Disguises traffic as Microsoft cloud traffic
- snowflake - Uses peer-to-peer connections
Troubleshooting
Tor Won't Connect
- Check your internet connection
- Try using bridges (Configure option)
- Check if your firewall is blocking Tor
- Try a different network
Sites Loading Slowly
- This is normal - Tor routes through multiple relays
- Click the lock icon > "New Circuit for this Site"
- Try at different times (network load varies)
Sites Not Working
- Try lowering security level temporarily
- Check if the site requires JavaScript
- The .onion site may be offline
Advanced Configuration
Accessing about:config
For advanced users, type about:config in the URL bar. Be careful - wrong settings can compromise your anonymity.
Useful Settings
javascript.enabled- false for maximum securitymedia.peerconnection.enabled- false (prevents WebRTC leaks)geo.enabled- false (already disabled by default)

Always use the latest version of Tor Browser:
- Tor Browser checks for updates automatically
- Never ignore update prompts
- Updates patch security vulnerabilities
- Outdated versions may be targeted by exploits
