what is a tor browser

Tor Browser is a special web browser that sends your traffic through the Tor network so that websites, trackers, and many observers cannot easily see who you are or where you are connecting from. It is free, open source, and widely used by privacyâconscious users, journalists, activists, and people bypassing censorship in 2026.
What is a Tor browser?
- Tor Browser is a modified version of Firefox that connects automatically to the Tor (The Onion Router) network.
- It hides your IP address by routing your data through several volunteerârun servers (nodes) before it reaches the website.
- Each âhopâ is encrypted in layers (like an onion), making it hard to trace traffic back to you.
In simple terms: instead of going straight from âyou â websiteâ, Tor goes âyou â node 1 â node 2 â node 3 â websiteâ, with multiple layers of encryption along the way.
How Tor Browser works (quick view)
- Onion routing: Your data is wrapped in multiple layers of encryption and passed through at least three Tor relays: entry, middle, and exit.
- Randomized path: The route is chosen randomly from thousands of volunteer nodes worldwide and periodically changes.
- Exit node: The last node decrypts the final layer and connects to the destination site; that site only sees the exit nodeâs IP, not yours.
Because of all these hops, Tor often feels slower than normal browsing, which is a tradeâoff for stronger anonymity.
What you can do with Tor Browser
- Browse normal websites (the âclearnetâ) more privately than with a standard browser.
- Access â.onionâ sites (hidden services) that only exist inside the Tor network (often called the dark web).
- Bypass local censorship and some regional blocks that rely on IPâbased filtering.
Legitimate uses include protecting sources, avoiding tracking, and researching sensitive topics in restrictive environments, though it can also be misused for illegal activities.
Is Tor Browser safe and legal?
- In most countries, simply using Tor Browser is legal, though it may draw extra attention from some networks or governments.
- Tor improves anonymity, but it does not make you invincible: malware, phishing, and bad operational security can still expose you.
- The exit node can see unencrypted traffic, so using HTTPS sites and avoiding logins or personal data on untrusted pages is crucial.
Many security guides recommend: do not install extra extensions, do not resize the window, and avoid logging into realâname accounts when using Tor, to keep your fingerprint similar to other users.
Pros and cons at a glance
| Aspect | Benefits | Limitations / Risks |
|---|---|---|
| Privacy | Hides IP, blocks many trackers, improves anonymity. | [5][1]Misuse or bad habits (logins, scripts) can still deanonymize you. | [6][5]
| Access | Reaches .onion sites and bypasses some censorship. | [7][1]Some sites block Tor or show more captchas. | [9][3]
| Speed | Acceptable for basic browsing and text content. | [5][7]Slower than normal browsers due to multiâhop routing. | [1][5]
| Security | Strong networkâlevel protections, hardened browser config. | [8][5]Exit nodes can see nonâHTTPS data; malware/phishing still dangerous. | [9][1]
