These are our currently recommended mobile web browsers and configurations for standard/non-anonymous internet browsing. If you need to browse the internet anonymously, you should use [Tor](tor.md) instead. In general, we recommend keeping extensions to a minimum; 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.
**Brave Browser** includes a built-in content blocker and [privacy features](https://brave.com/privacy-features), many of which are enabled by default.
Tor Browser is the only way to truly browse the internet anonymously. When you use Brave, we recommend changing the following settings to protect your privacy from certain parties, but all browsers other than the [Tor Browser](tor.md#tor-browser) will be traceable by *somebody* in some regard or another.
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.
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.
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.
1. InterPlanetary File System (IPFS) is a decentralized, peer-to-peer network for storing and sharing data in a distributed filesystem. Unless you use the feature, disable it.
[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.
**Mull** is a privacy oriented and deblobbed Android browser based on Firefox. Compared to Firefox, it offers much greater fingerprinting protection out of the box, and disables JavaScript Just-in-Time (JIT) compilation for enhanced security. It also removes all proprietary elements from Firefox, such as replacing Google Play Services references.
Firefox (Gecko)-based browsers on Android [lack](https://bugzilla.mozilla.org/show_bug.cgi?id=1610822) [site isolation](https://wiki.mozilla.org/Project_Fission),[^1] a powerful security feature that protects against a malicious site performing a [Spectre](https://en.wikipedia.org/wiki/Spectre_(security_vulnerability))-like attack to gain access to the memory of another website you have open.[^2] Chromium-based browsers like [Brave](#brave) will provide more robust protection against malicious websites.

[^1]: This should not be mistaken for [state partitioning](https://developer.mozilla.org/en-US/docs/Web/Privacy/State_Partitioning) (or dynamic [first party isolation](https://2019.www.torproject.org/projects/torbrowser/design/#identifier-linkability)), where website data such as cookies and cache is restricted so that a third-party embedded in one top-level site cannot access data stored under another top-level site. This is an important privacy feature to prevent cross-site tracking and **is** supported by Firefox on Android.
[^2]: GeckoView also [does not](https://bugzilla.mozilla.org/show_bug.cgi?id=1565196) take advantage of Android's native process sandboxing by using the [isolatedProcess](https://developer.android.com/guide/topics/manifest/service-element#isolated) flag, which normally allows an app to safely run less trusted code in a separate process that has no permissions of its own.
Enable DivestOS's [F-Droid Repo](https://divestos.org/fdroid/official) to receive updates directly from the developer. Downloading Mull from the default F-Droid repo will mean your updates could be delayed by a few days or longer.
Mull enables many features upstreamed by the [Tor uplift project](https://wiki.mozilla.org/Security/Tor_Uplift) using preferences from [Arkenfox](desktop-browsers.md#arkenfox-advanced). Proprietary blobs are removed from Mozilla's code using the scripts developed for Fennec F-Droid.
#### Recommended Mull Configuration
We would suggest installing [uBlock Origin](browser-extensions.md#ublock-origin) as a content blocker if you want to block trackers within Mull.
Mull comes with privacy protecting settings configured by default. You might consider configuring the **Delete browsing data on quit** options in Mull's settings if you want to close all your open tabs when quitting the app automatically, or clear other data such as browsing history and cookies automatically.
Because Mull has more advanced and strict privacy protections enabled by default compared to most browsers, some websites may not load or work properly unless you adjust those settings. You can consult this [list of known issues and workarounds](https://divestos.org/pages/broken#mull) for advice on a potential fix if you do encounter a broken site. Adjusting a setting in order to fix a website could impact your privacy/security, so make sure you fully understand any instructions you follow.
On iOS, any app that can browse the web is [restricted](https://developer.apple.com/app-store/review/guidelines) to using an Apple-provided [WebKit framework](https://developer.apple.com/documentation/webkit), so there is little reason to use a third-party web browser.
**Safari** is the default browser in iOS. It includes [privacy features](https://support.apple.com/guide/iphone/browse-the-web-privately-iphb01fc3c85/15.0/ios/15.0) such as [Intelligent Tracking Prevention](https://webkit.org/blog/7675/intelligent-tracking-prevention), Privacy Report, isolated and ephemeral Private Browsing tabs, iCloud Private Relay, fingerprinting protection by randomizing and presenting a simplified version of the system configuration to websites so more devices look identical, and the ability to lock private tabs with your biometrics/PIN. It also allows you to separate your browsing with different profiles.
All of your cookies, history, and website data will be separate for each profile. You should use different profiles for different purposes e.g. Shopping, Work, or School.
This enables WebKit's [Intelligent Tracking Protection](https://webkit.org/tracking-prevention/#intelligent-tracking-prevention-itp). The feature helps protect against unwanted tracking by using on-device machine learning to stop trackers. ITP protects against many common threats, but it does not block all tracking avenues because it is designed to not interfere with website usability.
- [x] Enable **Require Face ID to Unlock Private Browsing**
This setting allows you to lock your private tabs behind biometrics/PIN when not in use.
##### Advanced → Privacy
The **Advanced Tracking and Fingerprinting Protection** setting will randomize certain values so that it's more difficult to fingerprint you:
- [x] Select **All Browsing** or **Private Browsing**
Privacy Report provides a snapshot of cross-site trackers currently prevented from profiling you on the website you're visiting. It can also display a weekly report to show which trackers have been blocked over time.
Ad click measurement has traditionally used tracking technology that infringes on user privacy. [Private Click Measurement](https://webkit.org/blog/11529/introducing-private-click-measurement-pcm) is a WebKit feature and proposed web standard aimed towards allowing advertisers to measure the effectiveness of web campaigns without compromising on user privacy.
The feature has little privacy concerns on its own, so while you can choose to leave it on, we consider the fact that it's automatically disabled in Private Browsing to be an indicator for disabling the feature.
##### Always-on Private Browsing
Open Safari and tap the Tabs button, located in the bottom right. Then, expand the Tab Groups list.
- [x] Select **Private**
Safari's Private Browsing mode offers additional privacy protections. Private Browsing uses a new [ephemeral](https://developer.apple.com/documentation/foundation/urlsessionconfiguration/1410529-ephemeral) session for each tab, meaning tabs are isolated from one another. There are also other smaller privacy benefits with Private Browsing, such as not sending a webpage’s address to Apple when using Safari's translation feature.
Do note that Private Browsing does not save cookies and website data, so it won't be possible to remain signed into sites. This may be an inconvenience.
Synchronization of Safari History, Tab Groups, iCloud Tabs and saved passwords are E2EE. However, by default, bookmarks are [not](https://support.apple.com/HT202303). Apple can decrypt and access them in accordance with their [privacy policy](https://apple.com/legal/privacy/en-ww).
You can enable E2EE for your Safari bookmarks and downloads by enabling [Advanced Data Protection](https://support.apple.com/HT212520). Go to your **Apple ID name → iCloud → Advanced Data Protection**.
If you use iCloud with Advanced Data Protection disabled, we also recommend checking to ensure Safari's default download location is set to locally on your device. This option can be found in :gear: **Settings** → **Safari** → **General** → **Downloads**.
