**Tor** is a group of volunteer-operated servers that allows you to connect for free and improve your privacy and security on the Internet. Os indivíduos e organizações também podem compartilhar informações através da rede Tor com "serviços ocultos .onion", sem comprometer sua privacidade. Como o tráfego do Tor é difícil de bloquear e rastrear, o Tor é uma ferramenta eficaz para contornar a censura.
Before connecting to Tor, please ensure you've read our [overview](advanced/tor-overview.md) on what Tor is and how to connect to it safely. We often recommend connecting to Tor through a trusted [VPN provider](vpn.md), but you have to do so **properly** to avoid decreasing your anonymity.
There are a variety of ways to connect to the Tor network from your device, the most commonly used being the **Tor Browser**, a fork of Firefox designed for [:material-incognito: anonymous](basics/common-threats.md#anonymity-vs-privacy ""){.pg-purple} browsing for desktop computers and Android.
Some of these apps are better than others, and again making a determination comes down to your threat model. If you are a casual Tor user who is not worried about your ISP collecting evidence against you, using apps like [Orbot](#orbot) or mobile browser apps to access the Tor network is probably fine. Increasing the number of people who use Tor on an everyday basis helps reduce the bad stigma of Tor, and lowers the quality of "lists of Tor users" that ISPs and governments may compile.
If more complete anonymity is paramount to your situation, you should **only** be using the desktop Tor Browser client, ideally in a [Whonix](desktop.md#whonix) + [Qubes](desktop.md#qubes-os) configuration. Mobile browsers are less common on Tor (and more fingerprintable as a result), and other configurations are not as rigorously tested against de-anonymization.
O **Navegador Tor** é a melhor opção se você quer anonimato, pois ele fornece acesso à rede Tor e pontes, e inclui configurações padrão e extensões que são configuradas automaticamente pelos níveis de segurança: *Padrão*, *Mais seguro* e *O Mais Seguro*.
Você nunca deve instalar outras extensões no Navegador Tor ou editar as configurações em `about:config`, incluindo as que sugerimos para o Firefox. downloads
Este navegador dá acesso às Pontes Tor (Tor Bridges) e a \[Rede Tor\](https://en.wikipedia.org/wiki/Tor_(rede)), juntamente com extensões que podem ser configuradas automaticamente para se adaptarem aos três níveis de segurança propostos - *Standard*, *Safer* e *Safest*. Therefore, it is imperative that you do **not** modify the browser beyond the default [security levels](https://tb-manual.torproject.org/security-settings).
In addition to installing Tor Browser on your computer directly, there are also operating systems designed specifically to connect to the Tor network such as [Whonix](desktop.md#whonix) on [Qubes OS](desktop.md#qubes-os), which provide even greater security and protections than the standard Tor Browser alone.
Antes, recomendávamos habilitar a opção *"Isolar os endereços de destino"* (Isolate Destination Address) nas configurações do Orbot. Embora essa configuração possa, teoricamente, melhorar a privacidade, impondo o uso de um circuito diferente para cada endereço IP ao qual você se conecta, ela não fornece uma vantagem prática para a maioria dos aplicativos (especialmente a navegação na Internet), podendo vir com uma significativa perda de desempenho, e aumento da sobrecarga na rede Tor. We no longer recommend adjusting this setting from its default value unless you know you need to.[^1]
Orbot pode fazer proxy em aplicativos individuais se eles suportarem proxy SOCKS ou HTTP. It can also proxy all your network connections using [VpnService](https://developer.android.com/reference/android/net/VpnService) and can be used with the VPN killswitch in :gear: **Settings** → **Network & internet** → **VPN** → :gear: → **Block connections without VPN**.
Orbot costuma estar desatualizado no [repositório F-Droid, do Projeto Guardian](https://guardianproject.info/fdroid) e na [Google Play](https://play.google.com/store/apps/details?id=org.torproject.android), então, considere baixar diretamente do [repositório GitHub](https://github.com/guardianproject/orbot/releases) em vez disso.
All versions are signed using the same signature so they should be compatible with each other.
**Onion Browser** is an open-source browser that lets you browse the web anonymously over the Tor network on iOS devices and is endorsed by the [Tor Project](https://support.torproject.org/glossary/onion-browser). [:material-star-box: Read our latest Onion Browser review.](/articles/2024/09/18/onion-browser-review)
Onion Browser does not provide the same levels of privacy protections as Tor Browser does on desktop platforms. For casual use it is a perfectly fine way to access hidden services, but if you're concerned about being traced or monitored by advanced adversaries you should not rely on this as an anonymity tool.
[^1]: The `IsolateDestAddr` setting is discussed on the [Tor mailing list](https://lists.torproject.org/pipermail/tor-talk/2012-May/024403.html) and [Whonix's Stream Isolation documentation](https://whonix.org/wiki/Stream_Isolation), where both projects suggest that it is usually not a good approach for most people.
