What Tor Browser does and what it doesn't protect

Tor Browser routes your internet traffic through multiple volunteer-run servers around the world, making it harder for websites and your internet provider to see what you're doing. It does not make you invisible — it makes you harder to track. The dark web is simply websites that are not indexed by Google and require Tor Browser to reach. Some exist for legitimate reasons: journalists use them to receive tips, political dissidents use them to organize, and researchers study them. Others host illegal marketplaces. Tor Browser itself is legal in most countries, but what you do with it is not.

Tor Browser will not protect you from malware, from websites that trick you into revealing your identity, or from law enforcement if you break the law. It will not hide what you do once you arrive at a website — the site itself can still collect information about you. And it will not make your computer secure if your operating system or other software is already compromised.

Key Takeaways

  • Download Tor Browser only from torproject.org, never from a third-party site, because fake versions exist that steal data instead of protecting it.
  • Tor Browser works like a regular browser once installed — you open it, type an address, and browse — but pages load more slowly because traffic goes through multiple servers.
  • The dark web uses .onion addresses instead of .com or .org, and many sites change their addresses frequently to avoid being shut down.
  • Your internet provider can see that you are using Tor, even though they cannot see what you are doing, and some networks block it entirely.
  • Tor Browser alone does not keep you safe from scams, malware, or law enforcement — you also need to avoid clicking suspicious links and never maximize your browser window.

Download Tor Browser from the official source

Go to torproject.org in your regular browser. Look for the download button on the homepage — it will show your operating system (Windows, Mac, or Linux) automatically. Click it. The file that downloads is the official Tor Browser, signed and verified by the Tor Project.

Do not download Tor Browser from any other website, even if a search result claims to offer it. Fake versions exist that look identical but steal your data or install malware. If you are unsure whether a download is real, check the file's digital signature against the list on torproject.org/download — this takes a few minutes but confirms the file has not been tampered with.

Install and launch Tor Browser

On Windows, run the installer file and choose a folder to install it to. On Mac, drag the Tor Browser icon into your Applications folder. On Linux, extract the downloaded file and run the start-tor-browser script inside. The process is the same as installing any other program.

When you open Tor Browser for the first time, it will download the latest Tor software and connect to the Tor network. This takes 30 seconds to two minutes. You will see a window that says "Connecting to Tor" with a progress bar. Once it finishes, the browser opens and looks like Firefox — because it is based on Firefox. You can now browse the regular internet through Tor, or navigate to dark web sites using .onion addresses.

How to find and visit dark web sites

Dark web sites use addresses that end in .onion instead of .com or .org. These addresses are long strings of random characters — for example, a news site might be thehiddenwiki7654abcd.onion. You cannot find these addresses through Google. Instead, you use dark web directories and search engines that catalog .onion sites, such as the Hidden Wiki or Ahmia.

To visit a site, copy the .onion address into Tor Browser's address bar and press Enter. The page will load more slowly than regular websites because your traffic is being routed through multiple servers. Some sites are legitimate news outlets, libraries, or forums. Many others are scams or host illegal content. There is no verification system for .onion sites, so you have no way to know whether a site is what it claims to be.

Many dark web sites change their addresses frequently — sometimes weekly — to avoid being shut down by law enforcement. If a site you visited before no longer works, the address may have changed. Bookmark sites you trust and check for updated addresses on forums or news sites that cover the dark web.

Understand what your internet provider can and cannot see

Your internet provider can see that you are connecting to the Tor network. They cannot see which websites you visit or what you do on them, but they can see that you are using Tor at all. In some countries and on some networks, this alone is enough to trigger investigation or blocking. If you live in a place where Tor is monitored or blocked, you may need a VPN in addition to Tor — though this adds complexity and does not may provide safety.

Some workplaces, schools, and public networks block Tor entirely. If Tor Browser cannot connect, you are likely on a network that does not allow it. You cannot bypass this block without changing networks.

Protect yourself from common dangers

Do not maximize your Tor Browser window to full screen. Websites can detect your screen resolution, and if your resolution is unusual, it makes you easier to identify and track. Keep the window at a normal size.

Do not download files unless you are certain they are safe. Files downloaded through Tor can still contain malware. If you must download something, scan it with antivirus software before opening it.

Do not click links from untrusted sources. Many dark web sites are scams designed to steal cryptocurrency, passwords, or personal information. If a site asks you to enter a password, send money, or download software, assume it is a scam unless you have strong reason to believe otherwise.

Do not assume Tor makes you anonymous. Law enforcement has successfully identified Tor users by analyzing traffic patterns, by compromising Tor exit nodes, or by tricking users into revealing their identity. If you are doing something illegal, Tor reduces your risk but does not eliminate it.

Know what happens if your connection drops

If your Tor connection fails, Tor Browser will stop working but will not automatically fall back to your regular internet connection. This is intentional — it prevents you from accidentally browsing without Tor protection. If you see an error message, close Tor Browser and check your internet connection. Restart Tor Browser and try again.

If Tor Browser repeatedly fails to connect, your network may be blocking Tor, or the Tor network itself may be experiencing problems. Check the Tor Project's status page to see if there are known issues. If your network is blocking Tor, you will need to use a different network or contact your network administrator.

Frequently Asked Questions

Is using Tor Browser illegal?

No. Tor Browser is legal in most countries, including the United States, Canada, and most of Europe. Some countries restrict or monitor it, but possession and use are not crimes in most places. What you do with Tor Browser may be illegal — visiting certain sites, downloading certain files, or conducting certain transactions — but the software itself is not.

Can I be tracked if I use Tor Browser?

Tor makes tracking much harder, but not impossible. Websites can still see your activity once you arrive at them. Law enforcement can identify Tor users through traffic analysis, by compromising Tor nodes, or by tricking users into revealing their identity. Tor reduces your risk of being tracked, but does not eliminate it.

Why is Tor Browser so slow?

Because your traffic is routed through multiple volunteer-run servers around the world before reaching its destination, each hop adds latency. This is the trade-off for privacy — speed for anonymity. Some sites are slower than others depending on how many people are using Tor and where the servers are located.

What should I do if I find illegal content on the dark web?

If you encounter child exploitation material or other serious illegal content, you can report it to the National Center for Missing and Exploited Children (NCMEC) at CyberTipline.org, or to your local law enforcement. You do not need to provide your identity or Tor address — you can report anonymously.

Do I need a VPN with Tor Browser?

Using a VPN with Tor adds a layer of encryption, but also adds complexity and can actually reduce your anonymity if the VPN provider logs your activity. Most security researchers recommend using Tor alone rather than Tor plus VPN, unless you are in a country where Tor itself is blocked or monitored.
