These default settings, however, can be disabled. The autocomplete feature in all three browsers transmitted details of visited sites in real time as the URLs are being typed. In betweenĬhrome, Firefox, and Safari fell into a middle category. 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. The unique identifier allows Edge users to use a single click to delete associated diagnostic data stored on Microsoft servers.Īt the other end of the privacy spectrum was Brave. This default functionality can be disabled through the Edge Privacy and Services settings.

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. Users can view and delete this history on the privacy dashboard located at. When users are signed into Edge, they can sync their browser history to make it available on other devices.

While the data “may” contain information about visited websites, it isn’t stored with users’ Microsoft accounts. She said this collection can be turned off. She said that Edge asks for permission to collect diagnostic data that’s used to improve products. “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.Ī Microsoft representative provided a response on condition she not be named and the response not be quoted. These identifiers can then be used to track IP addresses over time. 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.

Yandex, 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. As Ars reader karinto pointed out in a comment, however, instructions for disabling the feature are here. The researcher said that the Edge autocomplete, which sends details of typed sites to a backend server, can’t be disabled. This identifier can’t easily be changed or deleted. Edge sends the universally unique identifier of a device to a Microsoft server located at .com. These unique strings, which can also link various apps running on the same device, remain the same even after fresh installs of the browsers. Strong, enduring identifiersīoth Edge and Yandex send identifiers that are tied to device hardware, the study found. 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. As far as we can tell this behaviour cannot be disabled by users. Edge also sends the hardware UUID of the device to Microsoft and Yandex similarly transmits a hashed hardware identifier to back end servers. Both send persistent identifiers that can be used to link requests (and associated IP address/location) to backend servers. 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.įrom a privacy perspective Microsoft Edge and Yandex are qualitatively different from the other browsers studied.

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. He analyzed and rated the privacy provided by Google Chrome, Mozilla Firefox, Apple Safari, Brave, Edge, and Yandex. The rankings were revealed in a research paper published by Trinity College Dublin computer scientist Doug Leith. Brave, the upstart browser that makes privacy a priority, ranked the highest. Yandex, the less-popular browser developed by the Russian Web search provider Yandex, shared that dubious distinction. Microsoft Edge received the lowest privacy rating in a recently published study that compared the user information collected by major browsers.
