We recommend [Mullvad Browser](#mullvad-browser) if you are focused on strong privacy protections and anti-fingerprinting out of the box, [Firefox](#firefox) for casual internet browsers looking for a good alternative to Google Chrome, and [Brave](#brave) if you need Chromium browser compatibility. If you need to browse the internet anonymously, you should use [Tor](tor.md) instead. We make some configuration recommendations on this page, but all browsers other than Tor Browser will be traceable by *somebody* in some manner or another. ## Mullvad Browser !!! recommendation ![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, aimed at providing Tor Browser's anti-fingerprinting browser technologies to VPN users. It is developed by the Tor Project and distributed by [Mullvad](vpn.md#mullvad), and does **not** require the use of Mullvad's VPN. [:octicons-home-16: Homepage](https://mullvad.net/en/browser){ .md-button .md-button--primary } [:octicons-eye-16:](https://mullvad.net/en/help/privacy-policy/){ .card-link title="Privacy Policy" } [:octicons-info-16:](https://mullvad.net/en/help/tag/mullvad-browser/){ .card-link title=Documentation} [:octicons-code-16:](https://gitlab.torproject.org/tpo/applications/mullvad-browser){ .card-link title="Source Code" } ??? downloads - [:simple-windows11: Windows](https://mullvad.net/en/download/browser/windows) - [:simple-apple: macOS](https://mullvad.net/en/download/browser/macos) - [:simple-linux: Linux](https://mullvad.net/en/download/browser/linux) 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/). Other modifications would make your fingerprint unique, defeating the purpose of using this browser. If you want to configure your browser more heavily and fingerprinting is not a concern for you, we recommend [Firefox](#firefox) instead. ### Anti-Fingerprinting **Without** using a [VPN](vpn.md), Mullvad Browser provides the same protections against [naive fingerprinting scripts](https://github.com/arkenfox/user.js/wiki/3.3-Overrides-%5BTo-RFP-or-Not%5D#-fingerprinting) as other private browsers like Firefox+[Arkenfox](#arkenfox-advanced) or [Brave](#brave). Mullvad Browser provides these protections out of the box, at the expense of some flexibility and convenience that other private browsers can provide. ==For the strongest anti-fingerprinting protection, we recommend using Mullvad Browser in conjunction **with** a VPN==, whether that is Mullvad or another recommended VPN provider. When using a VPN with Mullvad Browser, you will share a fingerprint and a pool of IP addresses with many other users, giving you a "crowd" to blend in with. This strategy is the only way to thwart advanced tracking scripts, and is the same anti-fingerprinting technique used by Tor Browser. Note that while you can use Mullvad Browser with any VPN provider, other people on that VPN must also be using Mullvad Browser for this "crowd" to exist, something which is more likely on Mullvad VPN compared to other providers, particularly this close to the launch of Mullvad Browser. Mullvad Browser does not have built-in VPN connectivity, nor does it check whether you are using a VPN before browsing; your VPN connection has to be configured and managed separately. Mullvad Browser comes with the *uBlock Origin* and *NoScript* browser extensions pre-installed. While we typically [don't recommend](#extensions) adding *additional* browser extensions, 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. It also comes pre-installed with the Mullvad Browser Extension, which *can* be safely removed without impacting your browser fingerprint if you would like, but is also safe to keep even if you don't use Mullvad VPN. ### Private Browsing Mode Mullvad Browser operates in permanent private browsing mode, meaning your history, cookies, and other site data will always be cleared every time the browser is closed. Your bookmarks, browser settings, and extension settings will still be preserved. This is required to prevent advanced forms of tracking, but does come at the cost of convenience and some Firefox features, such as Multi-Account Containers. Remember 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 don't work properly in Mullvad Browser, and Mullvad Browser for general browsing. ### Mullvad Leta Mullvad Browser comes with DuckDuckGo set as the default [search engine](search-engines.md), but it also comes preinstalled with **Mullvad Leta**, a search engine which requires an active Mullvad VPN subscription to access. Mullvad Leta queries Google's paid search API directly (which is why it is limited to paying subscribers), however because of this limitation it is possible for Mullvad to correlate search queries and Mullvad VPN accounts. For this reason we discourage the use of Mullvad Leta, even though Mullvad collects very little information about their VPN subscribers. ## Firefox !!! recommendation ![Firefox logo](assets/img/browsers/firefox.svg){ align=right } **Firefox** provides strong privacy settings such as [Enhanced Tracking Protection](https://support.mozilla.org/kb/enhanced-tracking-protection-firefox-desktop), which can help block various [types of tracking](https://support.mozilla.org/kb/enhanced-tracking-protection-firefox-desktop#w_what-enhanced-tracking-protection-blocks). [:octicons-home-16: Homepage](https://firefox.com){ .md-button .md-button--primary } [:octicons-eye-16:](https://www.mozilla.org/privacy/firefox/){ .card-link title="Privacy Policy" } [:octicons-info-16:](https://firefox-source-docs.mozilla.org/){ .card-link title=Documentation} [:octicons-code-16:](https://hg.mozilla.org/mozilla-central){ .card-link title="Source Code" } [:octicons-heart-16:](https://donate.mozilla.org/){ .card-link title=Contribute } ??? downloads - [:simple-windows11: Windows](https://www.mozilla.org/firefox/windows) - [:simple-apple: macOS](https://www.mozilla.org/firefox/mac) - [:simple-linux: Linux](https://www.mozilla.org/firefox/linux) - [:simple-flathub: Flathub](https://flathub.org/apps/details/org.mozilla.firefox) !!! warning 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/). ### Recommended Configuration These options can be found in :material-menu: → **Settings** #### Search - [ ] Uncheck **Provide 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. #### Privacy & Security ##### Enhanced Tracking Protection - [x] Select **Strict** Enhanced Tracking Protection 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. ##### Firefox Suggest (US only) [Firefox Suggest](https://support.mozilla.org/en-US/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 the web** - [ ] Uncheck **Suggestions from sponsors** ##### Sanitize on Close If you want to stay logged in to particular sites, you can allow exceptions in **Cookies and Site Data** → **Manage Exceptions...** - [x] Check **Delete cookies and site data when Firefox is closed** 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. ##### Telemetry - [ ] Uncheck **Allow Firefox to send technical and interaction data to Mozilla** - [ ] Uncheck **Allow Firefox to install and run studies** - [ ] Uncheck **Allow Firefox to send backlogged crash reports on your behalf** > Firefox sends data about your Firefox version and language; device operating system and hardware configuration; memory, basic information about crashes and errors; outcome of automated processes like updates, safebrowsing, and activation to us. When Firefox sends data to us, your IP address is temporarily collected as part of our server logs. Additionally, the Firefox Accounts service collects [some technical data](https://www.mozilla.org/en-US/privacy/firefox/#firefox-accounts). If you use a Firefox Account you can opt-out: 1. Open your [profile settings on accounts.firefox.com](https://accounts.firefox.com/settings#data-collection) 2. Uncheck **Data Collection and Use** > **Help improve Firefox Accounts** ##### HTTPS-Only Mode - [x] Select **Enable HTTPS-Only Mode in all windows** 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 over 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 (advanced) !!! tip "Use Mullvad Browser for advanced anti-fingerprinting" [Mullvad Browser](#mullvad-browser) provides the same anti-fingerprinting protections as Arkenfox out of the box, and does not require the use of Mullvad's VPN to benefit from these protections. Coupled with a VPN, Mullvad Browser can thwart more advanced tracking scripts which Arkenfox cannot. Arkenfox still has the advantage of being much more flexible, and allowing per-site exceptions for websites which you need to stay logged in to. 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/en-US/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 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 !!! recommendation ![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. Brave is built upon the Chromium web browser project, so it should feel familiar and have minimal website compatibility issues. [:octicons-home-16: Homepage](https://brave.com/){ .md-button .md-button--primary } [:simple-torbrowser:](https://brave4u7jddbv7cyviptqjc7jusxh72uik7zt6adtckl5f4nwy2v72qd.onion){ .card-link title="Onion Service" } [:octicons-eye-16:](https://brave.com/privacy/browser/){ .card-link title="Privacy Policy" } [:octicons-info-16:](https://support.brave.com/){ .card-link title=Documentation} [:octicons-code-16:](https://github.com/brave/brave-browser){ .card-link title="Source Code" } ??? downloads annotate - [:simple-github: GitHub](https://github.com/brave/brave-browser/releases) - [:simple-windows11: Windows](https://brave.com/download/) - [:simple-apple: macOS](https://brave.com/download/) - [:simple-linux: Linux](https://brave.com/linux/) (1) 1. We advise against using the Flatpak version of Brave, as it replaces Chromium's sandbox with Flatpak's, which is less effective. Additionally, the package is not maintained by Brave Software, Inc. **macOS users:** The download for Brave Browser from their official website is a `.pkg` installer which requires admin privileges to run (and may run other unnecessary scripts on your machine). As an alternative, you can download the latest `Brave-Browser-universal.dmg` file from their [GitHub releases](https://github.com/brave/brave-browser/releases/latest) page, which provides a traditional "drag to Applications folder" install. !!! warning 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. ### Recommended Configuration These options can be found in :material-menu: → **Settings**. #### Settings ##### Shields Brave includes some anti-fingerprinting measures in its [Shields](https://support.brave.com/hc/en-us/articles/360022973471-What-is-Shields-) feature. We suggest configuring these options [globally](https://support.brave.com/hc/en-us/articles/360023646212-How-do-I-configure-global-and-site-specific-Shields-settings-) across all pages that you visit. Shields' options can be downgraded on a per-site basis as needed, but by default we recommend setting the following:
- [x] Select **Prevent sites from fingerprinting me based on my language preferences** - [x] Select **Aggressive** under Trackers & ads blocking ??? warning "Use default filter lists" Brave allows you to select additional content filters within the internal `brave://adblock` page. We advise against using this feature; instead, keep the default filter lists. Using extra lists will make you stand out from other Brave users and may also increase attack surface if there is an exploit in Brave and a malicious rule is added to one of the lists you use. - [x] Select **Strict** under **Upgrade connections to HTTPS** - [x] (Optional) Select **Block Scripts** (1) - [x] Select **Strict, may break sites** under Block fingerprinting - [x] Check **Forget me when I close this site** (2)
1. This option provides functionality similar to uBlock Origin's advanced [blocking modes](https://github.com/gorhill/uBlock/wiki/Blocking-mode) or the [NoScript](https://noscript.net/) extension. 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. ##### Social media blocking - [ ] Uncheck all social media components ##### Privacy and security
- [x] Select **Disable non-proxied UDP** under [WebRTC IP Handling Policy](https://support.brave.com/hc/en-us/articles/360017989132-How-do-I-change-my-Privacy-Settings-#webrtc) - [ ] Uncheck **Use Google services for push messaging** - [ ] Uncheck **Allow privacy-preserving product analytics (P3A)** - [ ] Uncheck **Automatically send daily usage ping to Brave** - [ ] Uncheck **Automatically send diagnostic reports** - [ ] Uncheck **Private window with Tor** (1) !!! tip "Sanitizing on Close" - [x] Select **Clear cookies and site data when you close all windows** in the *Cookies and other site data* menu If you wish to stay logged in to a particular site you visit often, you can set exceptions on a per-site basis under the *Customized behaviors* section.
1. Brave is **not** as resistant to fingerprinting as the Tor Browser and far fewer people use Brave with Tor, so you will stand out. Where [strong anonymity is required](https://support.brave.com/hc/en-us/articles/360018121491-What-is-a-Private-Window-with-Tor-Connectivity-) use the [Tor Browser](tor.md#tor-browser). ##### Extensions Disable built-in extensions you do not use in **Extensions** - [ ] Uncheck **Hangouts** - [ ] Uncheck **WebTorrent** ##### Web3 Brave's Web3 features can potentially add to your browser fingerprint and attack surface. Unless you use any of features, they should be disabled. - Select **Extensions (no fallback)** under Default Ethereum wallet and Default Solana wallet - Set **Method to resolve IPFS resources** to **Disabled** ##### System
- [ ] Uncheck **Continue running apps when Brave is closed** to disable background apps (1)
1. This option is not present on all platforms. #### Sync [Brave Sync](https://support.brave.com/hc/en-us/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 recieve 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#other-coins-bitcoin-ethereum-etc), 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. ## Additional Resources In general, we recommend keeping your browser extensions to a minimum to decrease your attack surface; they have privileged access within your browser, require you to trust the developer, can make you [stand out](https://en.wikipedia.org/wiki/Device_fingerprint#Browser_fingerprint), and [weaken](https://groups.google.com/a/chromium.org/g/chromium-extensions/c/0ei-UCHNm34/m/lDaXwQhzBAAJ) site isolation. However, uBlock Origin may prove useful if you value content blocking functionality. ### uBlock Origin !!! recommendation ![uBlock Origin logo](assets/img/browsers/ublock_origin.svg){ align=right } **uBlock Origin** is a popular content blocker that could help you block ads, trackers, and fingerprinting scripts. [:octicons-repo-16: Repository](https://github.com/gorhill/uBlock#readme){ .md-button .md-button--primary } [:octicons-eye-16:](https://github.com/gorhill/uBlock/wiki/Privacy-policy){ .card-link title="Privacy Policy" } [:octicons-info-16:](https://github.com/gorhill/uBlock/wiki){ .card-link title=Documentation} [:octicons-code-16:](https://github.com/gorhill/uBlock){ .card-link title="Source Code" } ??? downloads - [:simple-firefoxbrowser: Firefox](https://addons.mozilla.org/firefox/addon/ublock-origin/) - [:simple-googlechrome: Chrome](https://chrome.google.com/webstore/detail/ublock-origin/cjpalhdlnbpafiamejdnhcphjbkeiagm) - [:simple-microsoftedge: Edge](https://microsoftedge.microsoft.com/addons/detail/ublock-origin/odfafepnkmbhccpbejgmiehpchacaeak) We suggest following the [developer's documentation](https://github.com/gorhill/uBlock/wiki/Blocking-mode) and picking one of the "modes". Additional filter lists can impact performance and [may increase attack surface](https://portswigger.net/research/ublock-i-exfiltrate-exploiting-ad-blockers-with-css). These are some other [filter lists](https://github.com/gorhill/uBlock/wiki/Dashboard:-Filter-lists) that you may want to consider adding: - [x] Check **Privacy** > **AdGuard URL Tracking Protection** - Add [Actually Legitimate URL Shortener Tool](https://raw.githubusercontent.com/DandelionSprout/adfilt/master/LegitimateURLShortener.txt) ### uBlock Origin Lite uBlock Origin also has a "Lite" version of their extension, which offers a very limited feature-set compared to the original extension. However, it has a few distinct advantages over its full-fledged sibling, so you may want to consider it if... - ...you don't want to grant full "read/modify website data" permissions to any extensions (even a trusted one like uBlock Origin) - ...you want a more resource (memory/CPU) efficient content blocker[^1] - ...your browser only supports Manifest V3 extensions !!! recommendation ![uBlock Origin Lite logo](assets/img/browsers/ublock_origin_lite.svg){ align=right } **uBlock Origin Lite** is a Manifest V3 compatible content blocker. Compared to the original *uBlock Origin*, this extension does not require broad "read/modify data" permissions to function. [:octicons-repo-16: Repository](https://github.com/uBlockOrigin/uBOL-home#readme){ .md-button .md-button--primary } [:octicons-eye-16:](https://github.com/gorhill/uBlock/wiki/Privacy-policy){ .card-link title="Privacy Policy" } [:octicons-info-16:](https://github.com/uBlockOrigin/uBOL-home/wiki){ .card-link title=Documentation} [:octicons-code-16:](https://github.com/gorhill/uBlock/tree/master/platform/mv3){ .card-link title="Source Code" } ??? downloads - [:simple-firefoxbrowser: Firefox](https://addons.mozilla.org/addon/ublock-origin-lite/) - [:simple-googlechrome: Chrome](https://chrome.google.com/webstore/detail/ublock-origin-lite/ddkjiahejlhfcafbddmgiahcphecmpfh) We only recommend this version of uBlock Origin if you never want to make any changes to your filter lists, because it only supports a few pre-selected lists and offers no additional customization options, including the ability to select elements to block manually. These restrictions are due to limitations in Manifest V3's design. This version offers three levels of blocking: "Basic" works without requiring any special privileges to view and modify site content, while the "Optimal" and "Complete" levels do require that broad permission, but offer a better filtering experience with additional cosmetic rules and scriptlet injections. If you set the default filtering mode to "Optimal" or "Complete" the extension will request read/modify access to **all** websites you visit. However, you also have the option to change the setting to "Optimal" or "Complete" on a **per-site** basis by adjusting the slider in the extension's pop-up panel on any given site. When you do so, the extension will request read/modify access to that site only. Therefore, if you want to take advantage of uBlock Origin Lite's "permission-less" configuration, you should probably leave the default setting as "Basic" and only adjust it higher on sites where that level is not adequate. uBlock Origin Lite only receives block list updates whenever the extension is updated from your browser's extension marketplace, as opposed to on demand. This means that you may miss out on new threats being blocked for weeks until a full extension release is published. ## Criteria **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. !!! example "This section is new" We are working on establishing defined criteria for every section of our site, and this may be subject to change. If you have any questions about our criteria, please [ask on our forum](https://discuss.privacyguides.net/latest) and don't assume we didn't consider something when making our recommendations if it is not listed here. There are many factors considered and discussed when we recommend a project, and documenting every single one is a work-in-progress. ### Minimum Requirements - Must be open-source software. - Supports automatic updates. - Receives engine updates in 0-1 days from upstream release. - Available on Linux, macOS, and Windows. - Any changes required to make the browser more privacy-respecting should not negatively impact user experience. - Blocks third-party cookies by default. - Supports [state partitioning](https://developer.mozilla.org/en-US/docs/Web/Privacy/State_Partitioning) to mitigate cross-site tracking.[^2] ### Best-Case Our best-case criteria represents what we would like to see from the perfect project in this category. Our recommendations may not include any or all of this functionality, but those which do may rank higher than others on this page. - Includes built-in content blocking functionality. - Supports cookie compartmentalization (à la [Multi-Account Containers](https://support.mozilla.org/en-US/kb/containers)). - Supports Progressive Web Apps. 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 you benefit from your browser's regular security updates. - Does not include add-on functionality (bloatware) that does not impact user privacy. - Does not collect telemetry by default. - Provides open-source sync server implementation. - Defaults to a [private search engine](search-engines.md). ### Extension Criteria - Must not replicate built-in browser or OS functionality. - Must directly impact user privacy, i.e. must not simply provide information. [^1]: uBlock Origin Lite *itself* will consume no resources, because it uses newer APIs which make the browser process the filter lists natively, instead of running JavaScript code within the extension to handle the filtering. However, this resource advantage is only [theoretical](https://github.com/uBlockOrigin/uBOL-home/wiki/Frequently-asked-questions-(FAQ)#is-ubol-more-efficient-cpu--and-memory-wise-than-ubo), because it's possible that standard uBlock Origin's filtering code is more efficient than your browser's native filtering code. This has not yet been benchmarked.
