Safari, Chrome, Firefox: Which is the most private browser for Mac? Posted on August 21st, 2019 by Kirk McElhearn and Joshua Long Everyone needs a web browser, and while Safari comes pre-installed on Macs, many people choose to use a different browser.
For the most-private browsing experience you need to use a VPN and a browser that doesn't collect user information—see below for more on this. Advertisement Chrome will make incognito mode. The Brave browser is a fast, private and secure web browser for PC, Mac and mobile. Download now to enjoy a faster ad-free browsing experience that saves data and battery life by blocking tracking software. The privacy risks of Chrome. Any discussion of privacy and Web browsers must begin with Google Chrome. It is, by far, the most popular Web browser. Chrome handles over 60 percent of web traffic. This is unfortunate because Google uses Chrome as a window to peer into every action you take online. Private browsing allows you to surf the web without leaving any traces behind. Google Chrome, Firefox, Chromium-based Edge, and Safari all including a private/incognito browsing mode.
Microsoft Edge received the lowest privacy rating in a recently published study that compared the user information collected by major browsers. Yandex, the less-popular browser developed by the Russian Web search provider Yandex, shared that dubious distinction. Brave, the upstart browser that makes privacy a priority, ranked the highest.
The rankings were revealed in a research paper published by Trinity College Dublin computer scientist Doug Leith. He analyzed and rated the privacy provided by Google Chrome, Mozilla Firefox, Apple Safari, Brave, Edge, and Yandex. Specifically, the study examined the browsers' sending of data—including unique identifiers and details related to typed URLs—that could be used to track users over time. The findings put the browsers into three categories with Brave getting the highest ranking, Chrome, Firefox, and Safari receiving a medium ranking, and Edge and Yandex lagging behind the rest.
In the paper, Leith wrote:
From a privacy perspective Microsoft Edge and Yandex are qualitatively different from the other browsers studied. Both send persistent identifiers that can be used to link requests (and associated IP address/location) to backend servers. Edge also sends the hardware UUID of the device to Microsoft and Yandex similarly transmits a hashed hardware identifier to back end servers. As far as we can tell this behaviour cannot be disabled by users. In addition to the search autocomplete functionality that shares details of web pages visited, both transmit web page information to servers that appear unrelated to search autocomplete.
Strong, enduring identifiers
Both Edge and Yandex send identifiers that are tied to device hardware, the study found. These unique strings, which can also link various apps running on the same device, remain the same even after fresh installs of the browsers. Edge sends the universally unique identifier of a device to a Microsoft server located at self.events.data.microsoft.com. This identifier can't easily be changed or deleted. The researcher said that the Edge autocomplete, which sends details of typed sites to a backend server, can't be disabled. As Ars reader karinto pointed out in a comment, however, instructions for disabling the feature are here.
AdvertisementYandex, meanwhile, collected a cryptographic hash of the hardware MAC address and details of visited websites through the autocomplete function, although the latter could be disabled. Because Edge and Yandex collect identifiers that are linked to the hardware running the browsers, the data persists across fresh browser installs and can also be used to link various apps running on the same device. These identifiers can then be used to track IP addresses over time.
'Transmission of device identifiers to backend servers is obviously the most worrisome since it is a strong, enduring identifier of a user device that can be regenerated at will, including by other apps (so allowing linking of data across apps from the same manufacturer) and cannot be easily changed or reset by users,' the paper warned. Os x capitan.
A Microsoft representative provided a response on condition she not be named and the response not be quoted. She gave no reason for this requirement. She said that Edge asks for permission to collect diagnostic data that's used to improve products. She said this collection can be turned off. While the data 'may' contain information about visited websites, it isn't stored with users' Microsoft accounts.
Browser syncing
When users are signed into Edge, they can sync their browser history to make it available on other devices. Users can view and delete this history on the privacy dashboard located at privacy.microsoft.com. Microsoft's Defender SmartScreen—a Windows 10 feature that protects against phishing and malware websites and the downloading of potentially malicious files—works by inspecting URLs that users intend to visit. This default functionality can be disabled through the Edge Privacy and Services settings.
The unique identifier allows Edge users to use a single click to delete associated diagnostic data stored on Microsoft servers.
At the other end of the privacy spectrum was Brave. The study found the default Brave settings provided the most privacy, with no collection of identifiers allowing the tracking of IP addresses over time and no sharing of the details of webpages visited with backend servers.
In between
Chrome, Firefox, and Safari fell into a middle category. The autocomplete feature in all three browsers transmitted details of visited sites in real time as the URLs are being typed. These default settings, however, can be disabled. Other potentially privacy-harming behaviors included: Change google drive account desktop.

- Firefox: includes identifiers in telemetry transmissions that can link these things over time (telemetry is on by default but can be disabled). Firefox also opens a persistent websocket for push notifications. The websocket, the researcher said, is linked to a unique identifier and can potentially be used for tracking that's not easily disabled.
- Safari: Defaults to a start page that can leak information to 'multiple third parties' who can preload pages containing identifiers to the browser cache. What's more, associated iCloud processes made connections containing identifiers.
Apple officials declined to comment on the report, but did point out that Safari by default provides blocking of third-party cookies and a complementary feature known as Intelligent Tracking Prevention, both of which limit the information third-party websites can obtain about users.

Browsing history is only sent to Mozilla if a user turns on our Sync service, whose purpose is to share data across a user's devices. Unlike other browsers, Sync data is end-to-end encrypted, so Mozilla cannot access it.
Firefox does collect some technical data about how users interact with our product, but that does not include the user's browsing history. This data is transmitted along with a unique randomly generated identifier. IP addresses are retained for a short period for security and fraud detection and then deleted. They are stripped from telemetry data and are not used to correlate user activity across browsing sessions.
As the study itself points out, 'transmission of user data to backend servers is not intrinsically a privacy intrusion.' By limiting collection and retention of data and safeguarding the data users do share with us through encryption and anonymization, Firefox works to protect people's privacy and provide a secure browsing experience. Clear and publicly available practices and processes reinforce our commitment to putting users' needs first.
Representatives of Googledidn't immediately provide responses to the findings. This post will be updated if responses come later. The research analyzed behavior of Chrome version 80.0.3987.87, Firefox 73.0, Brave 1.3.115, Safari 13.0.3, Edge 80.0.361.48, and Yandex 20.2.0.1145.
As Apple's background comment suggests, the study takes a narrow view of browser security, because it didn't take into account features that block third-party tracking. Still, the paper makes a good case why people using Edge, users of Chrome, Firefox, and Safari may want to disable the website autocomplete feature, which I've never found to be all that useful anyway. Microsoft's response above provides ways to curb some of the other data transmissions as well. While the browser comes with enhanced security measures that are resistant to exploits, users who prioritize privacy should consider disabling default behaviors or using a different browser.

Your web browser is the vehicle that carries you around the Internet to your desired websites. As such, it knows precisely what sites you have visited, how long you spent browsing them, and what you clicked on (or almost clicked on). Anyone who has access to your web browser can have a window into your income, your political leanings, and even your sexual preferences.
This is why it's so important to only use browsers you know will protect and improve your internet privacy. In this article, we explain how browsers capture so much information and which web browsers in 2019 are best at keeping your browsing history safe from data-hungry tech companies and advertisers

How you are tracked online
Before examining the impact your browser can have on your privacy, you need to understand how your online activity is monitored.
While having a company directly record your browsing history is a risk (see Google Chrome), the more common threats to your privacy come from online advertisers and third-party trackers. Similar to Google, advertisers and trackers want to record as much of your online browsing as possible. The more data they have, the better they can show you ads specifically tailored to you. The two tools they use to follow you around the Internet are device fingerprinting and cookies.
- Device fingerprinting is when a site looks at all the characteristics of your device (the make and model of your device, what browser you are using, what plugins you have installed, what timezone you are in, etc.) until it has enough information to identify and follow it. Your device share this information to optimize the websites you visit. For example, websites want to know if you're using a laptop or a smartphone so that it can select the correct font size and screen resolution. This can be surprisingly accurate. To see if your device has an easily identifiable fingerprint, check out the Electronic Frontier Foundation's Panopticlick.
- Cookies, or HTTP cookies, are tiny data packets that websites or services plant on your browser while you're on a website. These cookies differentiate your browsers from others, like a nametag.
The privacy risks of Chrome
Any discussion of privacy and Web browsers must begin with Google Chrome. It is, by far, the most popular Web browser. Chrome handles over 60 percent of web traffic. This is unfortunate because Google uses Chrome as a window to peer into every action you take online. Unless you modify your Google privacy settings, Chrome records every site you visit so Google can serve you targeted ads.
Even worse, Chrome does very little to block other advertisers and trackers from monitoring you with cookies or device fingerprinting. A Washington Post article reported Chrome gathers roughly 11,000 trackers in an average week. Do you want 11,000 pairs of eyes on you every time you do an Internet search?
However, you do not need to give away your personal data to access the Internet.
There are Internet browsers that do not record your every action and protect you from trackers. Switching from Chrome to one of the following browsers can drastically reduce the amount of data you are inadvertently sharing as you browse the Internet.

Best secure and privacy-first web browsers:
1. (tie) Brave
The Brave browser was designed to make privacy simple enough for everyone. It is an open source browser built on top of Chromium (an open source version of the Chrome browser), which means it's easy for Chrome users to make the switch.
However, unlike Chrome, Brave does not collect any data about your online activity. Your data remains private and on your device.
Free Private Web Browsers
Brave also makes blocking trackers easy. Instead of forcing users to decide which plugins and browser extensions they should download, Brave comes fully equipped. It automatically blocks all third-party and advertising cookies, and because HTTPS Everywhere is built-in, it ensures all your connections are securely HTTPS encrypted. Brave also features Fingerprinting Protection in the browser.
The company also has a social mission: to encourage websites not to rely on advertising based on tracking you around the Internet. Brave has introduced a system that allows you to reward creators and sites you visit directly.
Called Brave Rewards, it uses a utility token called a Basic Attention Token and enables you to anonymously reward the websites you visit most. Brave also has opt-in, privacy-preserving Brave Ads, and users who choose to view them earn 70% of the ad revenue, which they can then use to reward their favorite online creators.
Brave is available for desktop, Android, and iOS.
1. (tie) Firefox
The open source Firefox is the third-most-popular browser on the Internet, behind Google's Chrome and Apple's Safari. Developed by Mozilla, the Firefox team has improved the browser's privacy protections in recent years.
They have introduced advanced anti-fingerprinting and Enhanced Tracking Protection features this year, both of which make it much more difficult for third-party trackers to follow you around the Internet.
Unlike Brave, the standard Firefox does not automatically block advertisements. However, there are numerous browser extensions that you can download that will prevent advertisers from getting your information or showing you ads.
Or, if you primarily browse the Internet on your mobile device, Firefox Focus incorporates automatic ad blocking. (Focus was developed as an ad blocker for Safari, but was then transformed into a minimalistic privacy browser for Android users.)
Firefox is available for desktop, Android, and iOS.
3. Tor browser
As we have discussed elsewhere, Tor is the best option if privacy is your utmost concern. The Tor browser is based on Firefox, but it has been stripped down and specially calibrated to run on the Tor network.
When you use Tor, your traffic is encrypted three times and bounced between three Tor servers before it reaches your desired website. The encryption is handled in such a way that each server only has access to one set of instructions, so no server has access to both your IP address and the website you are visiting.
This setup makes it impossible for Tor to keep any records about your online activity, and every time you close your session, the browser deletes your cookie cache and browsing history. The browser itself is formatted to prevent fingerprinting, and it blocks all kinds of trackers.
Unfortunately, it also blocks a lot of plugins that websites rely on. For example, with its privacy settings fully activated, the Tor browser will block JavaScript. JavaScript can expose user information, but blocking it can make websites unusable. Using Tor can also mean performing endless CAPTCHA verifications when you try to access larger sites. Finally, the Tor browser is slower than other browsers because of the extra encryption.
Download the Tor browser app for desktop and Android, as well as a Tor-approved open source Onion browser for iOS.
4. DuckDuckGo (honorable mention)
Unlike the other browsers mentioned above, DuckDuckGo does not have a standalone desktop browser, which means it is only a solution if you are browsing the Internet on your smartphone or tablet. With the DuckDuckGo browser, your browsing history never leaves your device. Deleting your entire browsing history is as easy as tapping a single button.
It automatically blocks ads, stops third-party trackers, and ensures HTTPS encryption on all sites where that's possible. One feature that does set it apart is the Privacy Grade it gives each site. This makes it easy for you to evaluate how much data each website collects from you, with and without DuckDuckGo's protections, at a single glance.
The DuckDuckGo browser is available for Android and iOS.
You can also use the extension for Chrome and Firefox.
The Web browser you choose can have a dramatic impact on your overall online privacy. By switching to one of the privacy-focused browsers in this article, you can protect your browsing history from the companies and trackers that want to monitor your every digital move.
