What Tor Browser does and why people use it
Tor Browser is free software that routes your internet traffic through multiple servers to hide your location and identity from websites you visit. It does not make you invisible to your internet service provider or your network administrator — they can see that you are using Tor — but it prevents individual websites from learning your real IP address or tracking your physical location.
People use Tor for legitimate reasons: journalists protecting sources, activists in countries with censorship, people researching sensitive health topics, and anyone who wants a layer of privacy from commercial tracking. Tor also hosts hidden services — websites that exist only on the Tor network and cannot be accessed through a regular browser. Some of these are legitimate (activist forums, privacy-focused news sites), and some are illegal marketplaces. This guide covers safe use of Tor Browser itself, not how to find or use hidden services.
Tor Browser is maintained by the Tor Project, a nonprofit organization. The software is open-source, meaning anyone can read the code to verify it does what it claims. It is legal to download and use Tor Browser in most countries, though some governments discourage or monitor its use.
Key Takeaways
- Tor Browser is a free download from torproject.org that works on Windows, Mac, Linux, and Android, and it hides your IP address from websites but not from your internet service provider.
- Your connection will be noticeably slower because traffic is routed through multiple servers, and some websites will block Tor users or ask you to solve a CAPTCHA.
- Using Tor does not make you anonymous if you log into accounts with your real name, use plugins, or maximize your browser window to a size that identifies your device.
- Tor Browser updates frequently to patch security holes, so you should update it as soon as you see a notification rather than delaying.
- Do not download Tor from anywhere except torproject.org, because fake versions exist that steal data instead of protecting it.
Downloading Tor Browser from the official source
Go to torproject.org in any browser. On the homepage, you will see a large download button. Click it. The site will detect your operating system (Windows, Mac, or Linux) and offer the correct version. If you are on Android, look for the Tor Browser app in the Google Play Store — it is the official version maintained by the Tor Project.
Do not search for "Tor Browser download" in a search engine and click the first result. Scammers host fake versions that look identical but steal your data. The only safe source is torproject.org. If you are unsure whether you are on the real site, check the address bar: it should say torproject.org, not torproject.com or any variation.
After downloading, your browser may warn you that the file is unusual. This is normal — Tor Browser is not mainstream software. On Windows, you will get a .exe installer. On Mac, you will get a .dmg file. On Linux, you will get a compressed folder. Follow the standard installation steps for your operating system. You do not need to be a technical user to install it.
Starting Tor Browser and connecting to the network
Open Tor Browser like any other application. The first time you launch it, you will see a connection window that says "Connecting to Tor" with a progress bar. This can take 10 to 30 seconds. Do not close the window or restart your computer — let it finish. The browser is contacting Tor servers and building an encrypted path through the network.
Once connected, a regular browser window will open. It looks like Firefox (because Tor Browser is based on Firefox) but with a darker theme. You will see a Tor icon in the top left corner. If the icon is green and shows a checkmark, you are connected. If it is gray, the connection failed — try closing and reopening the browser.
Your first page will show a "Welcome to Tor Browser" message with a button that says "Check my Tor connection." Click it. A page will load showing your Tor exit IP address (the address websites see) and confirming that Tor is working. This address changes every 10 minutes by default, and it will be different from your real IP address.
Staying safe while using Tor: what to avoid
The biggest mistake people make is logging into personal accounts. If you open Gmail, Facebook, or any account with your real name, you have just told Tor Browser and the website exactly who you are. The privacy Tor provides is worthless if you volunteer your identity. Use Tor for browsing only, not for logging into accounts tied to your real life.
Do not maximize your browser window to fill your entire screen. Websites can see the size of your browser window, and if your window is a unique size, it can help identify you across different visits. Keep the window at a standard size or use the default size Tor Browser opens with.
Do not install plugins, extensions, or add-ons in Tor Browser. They can leak your real IP address or identify you in other ways. Tor Browser comes with the minimum software needed to work safely. If you want to add something, do not — use a different browser instead.
Do not open files downloaded through Tor in other applications immediately. Malware can use file metadata to identify you. If you download a PDF or document, open it in a sandboxed application (a program that runs in isolation) or in Tor Browser itself, not in your regular software.
Understanding what Tor does and does not protect
Tor hides your IP address from websites. When you visit a website through Tor, the website sees the IP address of a Tor exit node, not your real address. This prevents the website from learning your approximate location or linking your visits across time.
Tor does not encrypt your traffic from your internet service provider. Your ISP can see that you are using Tor, and they can see how much data you are sending and receiving, but they cannot see the content of your communications or which websites you visit. If your ISP is hostile to Tor users, they may throttle your speed or block the connection entirely.
Tor does not protect you from malware, phishing, or social engineering. If you download a file that contains a virus, Tor will not stop it. If a website tricks you into revealing information, Tor will not prevent it. You still need to use common sense: do not download files from untrusted sources, do not click suspicious links, and do not trust websites that ask for personal information.
Tor does not make you completely anonymous. If you use Tor to visit a website and then do something that identifies you — like typing your name, uploading a photo, or using a unique username — you have compromised your anonymity on that visit. Anonymity requires discipline across everything you do online.
Updating Tor Browser and recognizing security alerts
Tor Browser will notify you when an update is available. You will see a message in the browser or a notification when you open it. Update immediately. Tor Browser updates frequently because security researchers find vulnerabilities, and the Tor Project patches them quickly. Delaying updates leaves you exposed to attacks that could reveal your IP address or compromise your device.
To update, click the menu button (three horizontal lines) in the top right corner, then select "About Tor Browser." The browser will check for updates and install them automatically. You may need to restart the browser. This is normal and necessary.
If you see a warning message from Tor Browser itself (not from a website), take it seriously. Tor Browser will warn you if it detects that your connection is being monitored or if something is wrong with the Tor network. These warnings are rare, but when they appear, they indicate a real problem.
Troubleshooting common connection problems
If Tor Browser will not connect, first check that your internet connection is working by opening another browser and visiting a regular website. If that works, the problem is with Tor. Close Tor Browser completely and reopen it. Wait for the connection progress bar to finish — do not interrupt it.
If Tor still will not connect after 30 seconds, your network may be blocking Tor. Some workplaces, schools, and countries block connections to Tor servers. If you are on a network you do not control, you may not be able to use Tor there. If you are at home and Tor is blocked, contact your internet service provider to ask why.
If Tor connects but websites load very slowly, this is normal. Tor routes traffic through multiple servers, which adds latency. Some websites will also block Tor users or show a CAPTCHA (a puzzle asking you to prove you are human). This is not a problem with Tor — it is the website's choice to restrict access. You can either solve the CAPTCHA or visit a different website.
If you see an error message saying "Tor has exited unexpectedly," close the browser and reopen it. If this happens repeatedly, uninstall Tor Browser, restart your computer, and reinstall it from torproject.org. This resolves most persistent errors.
Frequently Asked Questions
Is using Tor Browser illegal?
No. Tor Browser is legal to download and use in most countries, including the United States, Canada, the United Kingdom, and most of Europe. Some countries discourage its use or monitor people who use it, but possession of the software itself is not a crime. Using Tor to commit crimes (like buying illegal goods) is illegal, but using Tor to browse the internet privately is not.
Can my internet service provider see what I am doing on Tor?
Your ISP can see that you are using Tor and how much data you are sending, but they cannot see which websites you visit or what you do on them. The traffic is encrypted. However, if you log into a personal account while using Tor, the website you log into will know who you are.
Why is Tor Browser so slow?
Tor routes your traffic through at least three different servers before reaching its destination. This adds time to every request. The slowness is a tradeoff for privacy. If speed is more important than privacy for a particular task, use a regular browser instead.
What is the dark web, and is it the same as Tor?
The dark web is a collection of websites that exist only on the Tor network and cannot be accessed through a regular browser. Tor is the software that lets you access it. They are related but not the same. You can use Tor Browser to browse the regular internet privately without ever visiting the dark web.
Should I use a VPN with Tor?
Using a VPN (virtual private network) with Tor is complicated and usually not necessary. A VPN can hide the fact that you are using Tor from your ISP, but it can also reduce your privacy if the VPN provider logs your activity. If you want to hide Tor usage from your ISP, research the specific VPN and Tor configuration before attempting it, or consult documentation from the Tor Project.
