**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 as organizações também podem partilhar informações através da rede Tor com os serviços ocultos ".onion", sem comprometer a sua privacidade. O facto do tráfego do Tor ser difícil de bloquear e rastrear, faz dele uma ferramenta eficaz para contornar a censura.

<p class="admonition-title">Tip</p>
|
|
|
|
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.
|
|
|
|
</div>
|
|
|
|
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 **Browser Tor** é a escolha certa se precisar de anonimato, uma vez que lhe dá acesso à rede Tor e às sua bridges, e inclui definições por defeito e extensões que são automaticamente configuradas com níveis de segurança predefinidos: *Standard*, *Seguro* e *Máxima Segurança*.

**Nunca** devem ser instaladas quaisquer extensões adicionais no Tor ou editadas as configurações `about:config`, incluindo as que sugerimos para o Firefox. Extensões e configurações não-padrão fazem com que se destaque dos outros utilizadores da rede Tor, tornando o seu browser mais suscetível a identificação de [fingerprint](https://support.torproject.org/glossary/browser-fingerprinting).
|
|
|
|
</div>
|
|
|
|
O Tor foi concebido para evitar a recolha de impressões digitais, ou a sua identificação com base na configuração. 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.

**Orbot** é uma VPN Tor gratuita para dispositivos móveis que encaminha o tráfego de qualquer aplicação no seu dispositivo através da rede Tor.

Anteriormente, recomendamos ativar a preferência *Isolar endereço de destino* nas configurações do Orbot. Enquanto esta configuração pode teoricamente melhorar a privacidade ao forçar o uso de um circuito diferente para cada endereço IP ao qual você se conecta, ela não fornece uma vantagem prática para a maioria das aplicações (especialmente navegação na web), pode vir com uma penalidade significativa de desempenho, e aumenta a carga na rede Tor. We no longer recommend adjusting this setting from its default value unless you know you need to.[^1]

Os dados de cada usuário são criptografados usando sua própria chave de criptografia exclusiva, e os arquivos do sistema operacional são deixados não criptografados. 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**.

O Orbot está frequentemente desatualizado no [repositório F-Droid](https://guardianproject.info/fdroid) e no [Google Play](https://play.google.com/store/apps/details?id=org.torproject.android) do Projeto Guardian, então considere fazer o download diretamente do [repositório GitHub](https://github.com/guardianproject/orbot/releases).

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.
