<small>Protects against the following threat(s):</small>

- [:material-account-cash: Capitalismo de vigilância](basics/common-threats.md#surveillance-as-a-business-model ""){.pg-brown}

These are our currently recommended **desktop web browsers** and configurations for standard/non-anonymous browsing. Recomendamos o [Mullvad Browser](#mullvad-browser) para quem pretenda fortes proteções de privacidade e ferramentas de bloqueio de impressão digital por defeito, o [Firefox](#firefox) para utilizadores casuais da internet que procurem uma boa alternativa ao Google Chrome e o [Brave](#brave) para quem necessite de compatibilidade com o Chromium.

Se precisar de navegar anonimamente na internet, deverá usar antes o [Tor](tor.md). Fazemos algumas recomendações de configuração nesta página, mas todos os browsers, com a exceção do Tor, são rastreáveis por *qualquer pessoa*, de uma maneira ou de outra.

## Mullvad Browser

<div class="admonition recommendation" markdown>

![Mullvad Browser logo](assets/img/browsers/mullvad_browser.svg){ align=right }

**Mullvad Browser** is a version of [Tor Browser](tor.md#tor-browser) with Tor network integrations removed. It aims to provide to VPN users Tor Browser's anti-fingerprinting browser technologies, which are key protections against [:material-eye-outline: Mass Surveillance](basics/common-threats.md#mass-surveillance-programs){ .pg-blue }. É desenvolvido pelo Projeto Tor e distribuído por [Mullvad](vpn.md#mullvad), e **não** requer a utilização da VPN do Mullvad.

</div>

Like [Tor Browser](tor.md), Mullvad Browser is designed to prevent fingerprinting by making your browser fingerprint identical to all other Mullvad Browser users, and it includes default settings and extensions that are automatically configured by the default security levels: *Standard*, *Safer* and *Safest*.

Therefore, it is imperative that you do not modify the browser at all outside adjusting the default [security levels](https://tb-manual.torproject.org/security-settings). When adjusting the security level, you **must** always restart the browser before continuing to use it. Otherwise, [the security settings may not be fully applied](https://www.privacyguides.org/articles/2025/05/02/tor-security-slider-flaw/), putting you at a higher risk of fingerprinting and exploits than you may expect based on the setting chosen.

Modifications other than adjusting this setting would make your fingerprint unique, defeating the purpose of using this browser. Se pretender configurar o seu browser de uma forma mais musculada e a impressão digital não for uma preocupação para si, recomendamos o [Firefox](#firefox).

### Bloqueio de impressão digital

**Mesmo sem** utilizar uma [VPN](vpn.md), o Mullvad Browser oferece as mesmas proteções contra [scripts naive de impressão digital](https://github.com/arkenfox/user.js/wiki/3.3-Overrides-%5BTo-RFP-or-Not%5D#-fingerprinting) que outros browsers privados, como o Firefox+[Arkenfox](#arkenfox-advanced) ou o [Brave](#brave). O Mullvad Browser disponibiliza estas proteções por defeito, com prejuízo de alguma flexibilidade e conveniência que outros browsers privados possam fornecer.

==Para obter a melhor proteção contra rastreamento de impressão digital, recomendamos a utilização do Mullvad Browser em conjunto **com** uma VPN==, quer seja o Mullvad ou outro fornecedor de VPN recomendado. Ao utilizar uma VPN com o Mullvad Browser, partilhará uma impressão digital e um conjunto de endereços IP com muitos outros utilizadores, fazendo com que a sua identidade se disperse na "multidão". Esta estratégia é a única forma de impedir scripts de rastreio avançados e é a mesma técnica de bloqueio de impressão digital utilizada pelo Tor.

Note que, embora possa utilizar o Mullvad Browser com qualquer fornecedor de VPN, é necessário que outras pessoas nessa VPN também estejam a utilizar o Mullvad Browser para que essa "multidão" exista, algo que é mais provável no Mullvad VPN do que noutros fornecedores, particularmente numa altura em que se está muito perto do lançamento do Mullvad Browser. O Mullvad Browser não tem conetividade VPN incorporada, nem verifica se se está a utilizar uma VPN; a ligação VPN tem de ser configurada e gerida separadamente.

O Mullvad Browser vem com as extensões de browser *uBlock Origin* e *NoScript* pré-instaladas. While we typically discourage adding *additional* [browser extensions](browser-extensions.md), these extensions that come pre-installed with the browser should **not** be removed or configured outside their default values, because doing so would noticeably make your browser fingerprint distinct from other Mullvad Browser users. A extensão de browser Mullvad vem pré-instalada, mas, se assim o desejar, *pode* ser removida com segurança sem afetar a impressão digital. No entanto, é seguro mantê-la, mesmo que não utilize o Mullvad VPN.

### Modo Privado do Browser

O Mullvad Browser funciona permanentemente em modo de navegação privada, o que significa que o seu histórico, cookies e outros dados de sites serão limpos sempre que o browser for fechado. Os seus marcadores, definições do browser e definições de extensões continuarão a ser preservados.

Este procedimento serve para evitar formas avançadas de rastreio, mas sacrifica a conveniência e perde algumas funcionalidades, como, por exemplo, os contentores para várias contas. Lembre-se que pode sempre utilizar vários browsers. Pode, por exemplo, considerar utilizar o Firefox+Arkenfox para alguns sites, nos quais pretende manter a sessão iniciada, ou que não funcionem corretamente no Mullvad Browser, e o Mullvad Browser para a navegação geral.

### Mullvad Leta

Mullvad Browser comes with [**Mullvad Leta**](https://leta.mullvad.net) as the default search engine, which functions as a proxy to either Google or Brave search results (configurable on the Mullvad Leta homepage).

If you are a Mullvad VPN user, there is some risk in using services like Mullvad Leta which are offered by your VPN provider themselves. This is because Mullvad theoretically has access to your true IP address (via their VPN) and your search activity (via Leta), which is information a VPN is typically intended to separate. Even though Mullvad collects very little information about their VPN subscribers or Leta users, you should consider a different [search engine](search-engines.md) if this risk concerns you.

## Firefox

<div class="admonition recommendation" markdown>

![Logótipo do Firefox](assets/img/browsers/firefox.svg){ align=right }

O **Firefox** possui definições de privacidade fortes, como a [Proteção Melhorada contra Monitorização] (https://support.mozilla.org/kb/enhanced-tracking-protection-firefox-desktop), que pode ajudar a bloquear vários [tipos de rastreio] (https://support.mozilla.org/kb/enhanced-tracking-protection-firefox-desktop#w_what-enhanced-tracking-protection-blocks).

</div>

<div class="admonition warning" markdown>
<p class="admonition-title">Aviso</p>

Firefox includes a unique [download token](https://bugzilla.mozilla.org/show_bug.cgi?id=1677497#c0) in downloads from Mozilla's website and uses telemetry in Firefox to send the token. The token is **not** included in releases from the [Mozilla FTP](https://ftp.mozilla.org/pub/firefox/releases/).

</div>

### Recommended Firefox Configuration

These options can be found in :material-menu: → **Settings**.

#### Pesquisa

- [ ] Uncheck **Show search suggestions**

Search suggestion features may not be available in your region.

Search suggestions send everything you type in the address bar to the default search engine, regardless of whether you submit an actual search. Disabling search suggestions allows you to more precisely control what data you send to your search engine provider.

##### Firefox Suggest (apenas nos EUA)

[Firefox Suggest](https://support.mozilla.org/kb/firefox-suggest) is a feature similar to search suggestions which is only available in the US. We recommend disabling it for the same reason we recommend disabling search suggestions. If you don't see these options under the **Address Bar** header, you do not have the new experience and can ignore these changes.

- [ ] Uncheck **Suggestions from Firefox**
- [ ] Desmarque **Sugestões de patrocinadores**

#### Privacidade & Segurança

##### Proteção melhorada contra a monitorização

- [x] Selecione **Rigorosa** Proteção mais forte

This protects you by blocking social media trackers, fingerprinting scripts (note that this does not protect you from *all* fingerprinting), cryptominers, cross-site tracking cookies, and some other tracking content. ETP protects against many common threats, but it does not block all tracking avenues because it is designed to have minimal to no impact on site usability.

##### Higienizar ao fechar

If you want to stay logged in to particular sites, you can allow exceptions in **Cookies and Site Data** → **Manage Exceptions...**

- [x] Selecione **Eliminar cookies e os dados de sites quando o Firefox é fechado**

This protects you from persistent cookies, but does not protect you against cookies acquired during any one browsing session. When this is enabled, it becomes possible to easily cleanse your browser cookies by simply restarting Firefox. You can set exceptions on a per-site basis, if you wish to stay logged in to a particular site you visit often.

##### Recolha de dados e utilização do Firefox

- [ ] Desmarque **Permitir que o Firefox envie dados técnicos e de interação para o Mozilla**
- [ ] Desmarque **Permitir ao Firefox instalar e executar estudos**
- [ ] Desmarque **Permitir que o Firefox envie relatórios de falhas acumuladas em seu nome**

According to Mozilla's privacy policy for Firefox,

> O Firefox envia-nos dados sobre a sua versão e idioma do Firefox; sistema operativo e configuração de hardware do dispositivo; memória, informações básicas sobre falhas e erros; resultado de processos automatizados como atualizações, navegação segura e ativação. Quando o Firefox nos envia dados, o seu endereço IP é temporariamente recolhido como parte dos registos do nosso servidor.

Additionally, the Mozilla Accounts service collects [some technical data](https://mozilla.org/privacy/mozilla-accounts). If you use a Mozilla Account you can opt out:

1. Abra as definições do seu perfil [em accounts.firefox.com](https://accounts.firefox.com/settings#data-collection)
2. Desmarque **Recolha e utilização de dados** > **Ajudar a melhorar as contas Firefox**

##### Website Advertising Preferences

- [ ] Uncheck **Allow websites to perform privacy-preserving ad measurement**

With the release of Firefox 128, a new setting for [privacy-preserving attribution](https://support.mozilla.org/kb/privacy-preserving-attribution) (PPA) has been added and [enabled by default](https://blog.privacyguides.org/2024/07/14/mozilla-disappoints-us-yet-again-2). PPA allows advertisers to use your web browser to measure the effectiveness of web campaigns, instead of using traditional JavaScript-based tracking. We consider this behavior to be outside the scope of a user agent's responsibilities, and the fact that it is disabled by default in Arkenfox is an additional indicator for disabling this feature.

##### HTTPS-Only Mode

- [x] Selecione **Ativar o modo apenas HTTPS em todas as janelas**

This prevents you from unintentionally connecting to a website in plain-text HTTP. Sites without HTTPS are uncommon nowadays, so this should have little to no impact on your day-to-day browsing.

##### DNS sobre HTTPS

If you use a [DNS over HTTPS provider](dns.md):

- [x] Select **Max Protection** and choose a suitable provider

Max Protection enforces the use of DNS over HTTPS, and a security warning will show if Firefox can’t connect to your secure DNS resolver, or if your secure DNS resolver says that records for the domain you are trying to access do not exist. This stops the network you're connected to from secretly downgrading your DNS security.

#### Sync

[Firefox Sync](https://hacks.mozilla.org/2018/11/firefox-sync-privacy) allows your browsing data (history, bookmarks, etc.) to be accessible on all your devices and protects it with E2EE.

### Arkenfox (avançado)

<div class="admonition tip" markdown>
<p class="admonition-title">Usa o Mullvad Browser para Bloqueio de Impressão Digital Avançado</p>

O [Mullvad Browser](#mullvad-browser) fornece as mesmas proteções de bloqueio de impressão digital que o Arkenfox, e não requer a utilização da VPN do Mullvad para o efeito. Juntamente com uma VPN, o Mullvad Browser pode impedir scripts de rastreio mais avançados, algo que o Arkenfox não consegue. O Arkenfox tem a vantagem de ser muito mais flexível e de permitir exceções por site, nos casos em que é necessário manter a sessão iniciada.

</div>

The [Arkenfox project](https://github.com/arkenfox/user.js) provides a set of carefully considered options for Firefox. If you [decide](https://github.com/arkenfox/user.js/wiki/1.1-To-Arkenfox-or-Not) to use Arkenfox, a [few options](https://github.com/arkenfox/user.js/wiki/3.2-Overrides-[Common]) are subjectively strict and/or may cause some websites to not work properly—which you can [easily change](https://github.com/arkenfox/user.js/wiki/3.1-Overrides) to suit your needs. We **strongly recommend** reading through their full [wiki](https://github.com/arkenfox/user.js/wiki). Arkenfox also enables [container](https://support.mozilla.org/kb/containers#w_for-advanced-users) support.

Arkenfox only aims to thwart basic or naive tracking scripts through canvas randomization and Firefox's built-in fingerprint resistance configuration settings. It does not aim to make your browser blend in with a large crowd of other Arkenfox users in the same way Mullvad Browser or Tor Browser do, which is the only way to thwart advanced fingerprint tracking scripts. Remember that you can always use multiple browsers, for example, you could consider using Firefox+Arkenfox for a few sites that you want to stay logged in on or otherwise trust, and Mullvad Browser for general browsing.

## Brave

<div class="admonition recommendation annotate" markdown>

![Brave logo](assets/img/browsers/brave.svg){ align=right }

**Brave Browser** includes a built-in content blocker and [privacy features](https://brave.com/privacy-features), many of which are enabled by default.

O Brave foi desenvolvido com base no projeto do Chromium, pelo que deve ser familiar a muitos utilizadores e não deverá ter grandes problemas de compatibilidade com sites.

</details>

</div>

<div class="admonition warning" markdown>
<p class="admonition-title">Warning</p>

Brave adds a "[referral code](https://github.com/brave/brave-browser/wiki/Brave%E2%80%99s-Use-of-Referral-Codes)" to the file name in downloads from the Brave website, which is used to track which source the browser was downloaded from, for example `BRV002` in a download named `Brave-Browser-BRV002.pkg`. The installer will then ping Brave's server with the referral code at the end of the installation process. If you're concerned about this, you can rename the installer file before opening it.

</div>

### Recommended Brave Configuration

These options can be found in :material-menu: → **Settings**.

#### Shields

Brave includes some anti-fingerprinting measures in its [Shields](https://support.brave.com/hc/articles/360022973471-What-is-Shields) feature. We suggest configuring these options [globally](https://support.brave.com/hc/articles/360023646212-How-do-I-configure-global-and-site-specific-Shields-settings) across all pages that you visit.

As opções de proteção podem ser revogadas por cada site, de acordo com as necessidades, mas por predefinição recomendamos as seguintes definições:

<div class="annotate" markdown>

- [x] Select **Aggressive** under *Trackers & ads blocking*

<details class="warning" markdown>
<summary>Use default filter lists</summary>

Brave allows you to select additional content filters within the internal `brave://adblock` page. Aconselhamos a não utilizar esta funcionalidade; em vez disso, mantenha as listas de filtros predefinidas. A utilização de listas extra fará com que se destaque dos outros utilizadores do Brave e pode também aumentar a superfície de ataque se houver uma vulnerabilidade no Brave e uma regra maliciosa for adicionada a uma das listas que utiliza.

</details>

- [x] Select **Strict** under *Upgrade connections to HTTPS*
- [x] (Optional) Select **Block Scripts** (1)
- [x] Check **Block fingerprinting**
- [x] Select **Block third-party cookies**
- [x] Check **Forget me when I close this site** (2)
- [ ] Uncheck all social media components

</div>

1. This option disables JavaScript, which will break a lot of sites. To fix them, you can set exceptions on a per-site basis by clicking on the Shield icon in the address bar and unchecking this setting under *Advanced controls*.
2. If you wish to stay logged in to a particular site you visit often, you can set exceptions on a per-site basis by clicking on the Shield icon in the address bar and unchecking this setting under *Advanced controls*.

#### Privacy and security

<div class="annotate" markdown>

- [x] Select **Don't allow sites to use the V8 optimizer** under *Security* → *Manage V8 security* (1)
- [x] Select **Automatically remove permissions from unused sites** under *Sites and Shields Settings*
- [x] Select **Disable non-proxied UDP** under [*WebRTC IP Handling Policy*](https://support.brave.com/hc/articles/360017989132-How-do-I-change-my-Privacy-Settings#webrtc)
- [ ] Uncheck **Use Google services for push messaging**
- [x] Select **Auto-redirect AMP pages**
- [x] Select **Auto-redirect tracking URLs**
- [x] Select **Prevent sites from fingerprinting me based on my language preferences**

</div>

1. Disabling the V8 optimizer reduces your attack surface by disabling [*some*](https://grapheneos.social/@GrapheneOS/112708049232710156) parts of JavaScript Just-In-Time (JIT) compilation.

##### Tor windows

[**Private Window with Tor**](https://support.brave.com/hc/articles/360018121491-What-is-a-Private-Window-with-Tor-Connectivity) allows you to route your traffic through the Tor network in Private Windows and access .onion services, which may be useful in some cases. However, Brave is **not** as resistant to fingerprinting as the Tor Browser is, and far fewer people use Brave with Tor, so you will stand out. If your threat model requires strong anonymity, use the [Tor Browser](tor.md#tor-browser).

##### Data Collection

- [ ] Uncheck **Allow privacy-preserving product analytics (P3A)**
- [ ] Uncheck **Automatically send daily usage ping to Brave**
- [ ] Uncheck **Automatically send diagnostic reports**

#### Web3

Brave's Web3 features can potentially add to your browser fingerprint and attack surface. Unless you use any of these features, they should be disabled.

- Select **Extensions (no fallback)** under *Default Ethereum wallet*
- Select **Extensions (no fallback)** under *Default Solana wallet*

#### Extensions

- [ ] Uncheck all built-in extensions you don't use

#### Search engine

We recommend disabling search suggestions in Brave for the same reason we recommend disabling this feature in [Firefox](#search).

- [ ] Uncheck **Show search suggestions**

#### System

<div class="annotate" markdown>

- [ ] Desmarque a opção **Continuar a executar aplicações quando o Brave é fechado** para desativar as aplicações em segundo plano (1)

</div>

1. Esta opção não está presente em todas as plataformas.

#### Brave Sync

[Brave Sync](https://support.brave.com/hc/articles/360059793111-Understanding-Brave-Sync) allows your browsing data (history, bookmarks, etc.) to be accessible on all your devices without requiring an account and protects it with E2EE.

#### Brave Rewards and Wallet

**Brave Rewards** lets you receive Basic Attention Token (BAT) cryptocurrency for performing certain actions within Brave. It relies on a custodial account and KYC from a select number of providers. We do not recommend BAT as a [private cryptocurrency](cryptocurrency.md), nor do we recommend using a [custodial wallet](advanced/payments.md#wallet-custody), so we would discourage using this feature.

**Brave Wallet** operates locally on your computer, but does not support any private cryptocurrencies, so we would discourage using this feature as well.

## Critérios

**Please note we are not affiliated with any of the projects we recommend.** In addition to [our standard criteria](about/criteria.md), we have developed a clear set of requirements to allow us to provide objective recommendations. We suggest you familiarize yourself with this list before choosing to use a project, and conduct your own research to ensure it's the right choice for you.

### Requisitos mínimos

- Software de código aberto.
- Deve suportar atualizações automáticas.
- Must receive engine updates in 0-1 days from upstream release.
- Must be available on Linux, macOS, and Windows.
- Any changes required to make the browser more privacy-respecting must not negatively impact user experience.
- Must block third-party cookies by default.
- Must support [state partitioning](https://developer.mozilla.org/docs/Web/Privacy/State_Partitioning) to mitigate cross-site tracking.[^1]

### Melhor caso

Os nossos melhores critérios representam o que gostaríamos de ver num projeto perfeito desta categoria. As nossas recomendações podem não incluir todas as funcionalidades, mas incluem as que, na nossa opinião, têm um impacto mais elevado.

- Should include built-in content blocking functionality.
- Should support cookie compartmentalization (à la [Multi-Account Containers](https://support.mozilla.org/kb/containers)).
- Should support Progressive Web Apps (PWAs). PWAs enable you to install certain websites as if they were native apps on your computer. This can have advantages over installing Electron-based apps because PWAs benefit from your browser's regular security updates.
- Should not include add-on functionality (bloatware) that does not impact user privacy.
- Should not collect telemetry by default.
- Should provide an open-source sync server implementation.
- Should default to a [private search engine](search-engines.md).

[^1]: Brave's implementation is detailed at [Brave Privacy Updates: Partitioning network-state for privacy](https://brave.com/privacy-updates/14-partitioning-network-state).
