We do not recommend using Tor with BitTorrent. For further details, please see our blog post on the subject.

Thank you for your support! You can find more information about donating on our donor FAQ.

Tor is designed to defend human rights and privacy by preventing anyone from censoring things, even us. We hate that there are some people who use Tor to do terrible things, but we can't do anything to get rid of them without also undermining the human rights activists, journalists, abuse survivors, and other people who use Tor for good things. If we wanted to block certain people from using Tor, we'd basically be adding a backdoor to the software, which would open up our vulnerable users to attacks from bad regimes and other adversaries.

There are a few reasons we don't:

1. We can't help but make the information available, since Tor clients need to use it to pick their paths. So if the "blockers" want it, they can get it anyway. Further, even if we didn't tell clients about the list of relays directly, somebody could still make a lot of connections through Tor to a test site and build a list of the addresses they see.
2. If people want to block us, we believe that they should be allowed to do so. Obviously, we would prefer for everybody to allow Tor users to connect to them, but people have the right to decide who their services should allow connections from, and if they want to block anonymous users, they can.
3. Being blockable also has tactical advantages: it may be a persuasive response to website maintainers who feel threatened by Tor. Giving them the option may inspire them to stop and think about whether they really want to eliminate private access to their system, and if not, what other options they might have. The time they might otherwise have spent blocking Tor, they may instead spend rethinking their overall approach to privacy and anonymity.

You can read all about that on our Trademark faq page.

A few things everyone can do now:

1. Please consider running a relay to help the Tor network grow.
2. Tell your friends! Get them to run relays. Get them to run onion services. Get them to tell their friends.
3. If you like Tor's goals, please take a moment to donate to support further Tor development. We're also looking for more sponsors - if you know any companies, NGOs, agencies, or other organizations that want anonymity / privacy / communications security, let them know about us.
4. We're looking for more good examples of Tor users and Tor use cases. If you use Tor for a scenario or purpose not yet described on that page, and you're comfortable sharing it with us, we'd love to hear from you.

Documentation

1. Help localize the documentation into other languages. See becoming a Tor translator if you want to help out. We especially need Arabic or Farsi translations, for the many Tor users in censored areas.

Advocacy

1. The Tor community uses the Tor Forum, IRC/Matrix, and public mailing lists.
2. Create a presentation that can be used for various user group meetings around the world.
3. Create a poster around a theme, such as "Tor for Human Rights!".
4. Spread the word about Tor at a symposium or conference and use these Tor brochures as conversation starter.

There is nothing the Tor developers can do to trace Tor users. The same protections that keep bad people from breaking Tor's anonymity also prevent us from tracking users.

Vidalia is no longer maintained or supported. A large portion of the features Vidalia offered have now been integrated into Tor Browser itself.

Tor is afhankelijk van de steun van haar wereldwijde gebruikers en vrijwilligers om te helpen onze software en middelen te verbeteren, dus jou terugkoppeling is zeer waardevol voor ons (en voor alle Tor-gebruikers).

Feedback template

When sending us feedback or reporting a bug, please include as many of these as possible:

• Operating System you are using
• Tor Browser version
• Tor Browser Security Level
• Step by step of how you got to the issue, so we can reproduce it (e.g. I opened the browser, typed a url, clicked on (i) icon, then my browser crashed)
• A screenshot of the problem
• The log

Hoe je ons kunt bereiken

Er zijn verschillende manieren om ons te bereiken, dus gebruik wat voor jou het beste werkt.

Tor Forum

We recommend asking for help on the Tor Forum. You will need to create an account to submit a new topic. Before you ask, please review our discussion guidelines. Schrijf op dit moment in het Engels om zo snel mogelijk antwoord te krijgen. If you found a bug, please use GitLab.

GitLab

Controleer eerst of de fout al gekend is. Je kan alle probleemmeldingen doorzoeken en lezen op https://gitlab.torproject.org/. Om een nieuw probleemmelding aan te maken, vraag een nieuw account aan om toegang te krijgen tot de GitLab instantie van het Tor Project en vind de juiste repository om je probleem te rapporteren. We volgen alle Tor Browser gerelateerde problemen via Tor Browser issue tracker. Problemen met betrekking tot onze websites moeten worden ingediend onder de Web issue tracker.

Telegram

If you need help installing or troubleshooting Tor Browser and the Tor Forum is blocked or censored where you are, you can reach out to us on Telegram https://t.me/TorProjectSupportBot. A Tor support specialist will assist you.

WhatsApp

Je kunt ons ondersteuningsteam bereiken door een tekstbericht te sturen naar ons WhatsApp-nummer: +447421000612. Deze dienst is alleen beschikbaar voor tekstberichten; video's of oproepen worden niet ondersteund.

Signal

Je kunt hulp krijgen door een sms te sturen naar ons Signalnummer: +17787431312.

E-mail

Send us an email to frontdesk@torproject.org.

Vertel ons in de onderwerpregel van je e-mail wat je meldt. Hoe specifieker je onderwerpregel is (bijvoorbeeld "verbindingsfout", "feedback over website", "feedback over Tor Browser, "ik heb een brug nodig"), hoe makkelijker het voor ons is om dit te begrijpen en op te volgen. Soms worden e-mails zonder onderwerpregel gemarkeerd als spam en zien we ze niet.

For the fastest response, please write in English, Spanish, and/or Portuguese if you can. Als geen van deze talen werkt voor jou, schrijf dan in elke taal waar jij je goed bij voelt, maar houd er rekening mee dat het iets langer duurt om te antwoorden omdat we hulp nodig hebben bij het vertalen om het te begrijpen.

Blog post comments

You can always leave comments on the blog post related to the issue or feedback you want to report. If there is not a blog post related to your issue, please contact us another way.

IRC

You can find us in the #tor channel on OFTC to give us feedback or report bugs/issues. We may not respond right away, but we do check the backlog and will get back to you when we can.

If you wish to participate in our bug bounty program, please be aware, submitting a security issue to a third-party website carries certain risks that we cannot control, as a result we'd prefer the report directly.

No. After eleven beta releases, we discontinued support of Tor Messenger. We still believe in Tor's ability to be used in a messaging app, but we don't have the resources to make it happen right now. Do you? Contact us.

We are so sorry, but you have been infected with malware. The Tor Project did not create this malware. The malware authors are asking you to download Tor Browser presumably to contact them anonymously with the ransom they're demanding from you.

If this is your first introduction to Tor Browser, we understand that you might think we're bad people who enable even worse people.

But please consider that our software is used every day for a wide variety of purposes by human rights activists, journalists, domestic violence survivors, whistleblowers, law enforcement officers, and many others. Unfortunately, the protection that our software can provide to these groups of people can also be abused by criminals and malware authors. The Tor Project does not support or condone the use of our software for malicious purposes.

Even if your application is using the correct variant of the SOCKS protocol, there is still a risk that it could be leaking DNS queries. This problem happens in Firefox extensions that resolve the destination hostname themselves, for example to show you its IP address, what country it's in, etc. If you suspect your application might behave like this, follow the instructions below to check.

1. Add TestSocks 1 to your torrc file.
2. Start Tor, and point your program's SOCKS proxy settings to Tor's SOCKS5 server (socks5://127.0.0.1:9050 by default).
3. Watch your logs as you use your application. For each socks connection, Tor will log a notice for safe connections, and a warn for connections leaking DNS requests.

If you want to automatically disable all connections leaking DNS requests, set SafeSocks 1 in your torrc file.

Tor doesn't keep any logs that could identify a particular user. We do take some safe measurements of how the network functions, which you can check out at Tor Metrics.

Tor is funded by a number of different sponsors including US federal agencies, private foundations, and individual donors. Check out a list of all our sponsors and a series of blog posts on our financial reports.

We feel that talking openly about our sponsors and funding model is the best way to maintain trust with our community. We are always seeking more diversity in our funding sources, especially from foundations and individuals.

For sharing files over Tor, OnionShare is a good option. OnionShare is an open source tool for securely and anonymously sending and receiving files using Tor onion services. It works by starting a web server directly on your computer and making it accessible as an unguessable Tor web address that others can load in Tor Browser to download files from you, or upload files to you. It doesn't require setting up a separate server, using a third party file-sharing service, or even logging into an account.

Unlike services like email, Google Drive, DropBox, WeTransfer, or nearly any other way people typically send files to each other, when you use OnionShare you don't give any companies access to the files that you're sharing. So long as you share the unguessable web address in a secure way (like pasting it in an encrypted messaging app), no one but you and the person you're sharing with can access the files.

OnionShare is developed by Micah Lee.

Many exit nodes are configured to block certain types of file sharing traffic, such as BitTorrent. BitTorrent in particular is not anonymous over Tor.

No, the Tor Project does not offer hosting services.

No, we don't provide any online services. A list of all of our software projects can be found on our projects page.

Right now the path length is hard-coded at 3 plus the number of nodes in your path that are sensitive. That is, in normal cases it's 3, but for example if you're accessing an onion service or a ".exit" address it could be more.

We don't want to encourage people to use paths longer than this as it increases load on the network without (as far as we can tell) providing any more security. Also, using paths longer than 3 could harm anonymity, first because it makes denial of security attacks easier, and second because it could act as an identifier if only a small number of users have the same path length as you.
