[QUOTE="silversurfer, post: 862005, member: 26718"] [URL unfurl="true"]https://www.ghacks.net/2020/02/25/study-finds-brave-to-be-the-most-private-browser/[/URL] Are you concerned about your web browser sending data back to the company that created it? [URL='https://www.scss.tcd.ie/Doug.Leith/pubs/browser_privacy.pdf']A new study[/URL], Web Browser Privacy: What Do Browsers Say When They Phone Home?, looked at the six popular desktop web browsers Google Chrome, Mozilla Firefox, Microsoft Edge (Chromium-based), Apple Safari, Brave, and Yandex, to uncover what these browsers send back to the mothership. If you just want the result, the study found that used out of the box, Brave "is by far the most private of the browsers studied" followed by Chrome, Firefox and Safari. Brave is the only web browser that did not use identifiers that allowed tracking of the IP address over time and did not share details of web pages visited to backend servers. Chrome, Firefox and Safari used identifiers that are linked to the browser instance that persist over sessions and all three share web page details with backend servers via the browser's search autocomplete functionality. The study found the Chromium-based Microsoft Edge web browser and Yandex to do worse than the other browsers of the test. Both send identifiers linked to the device hardware which means that the identifier persists even across installations. Edge sends the hardware UUID to Microsoft, and Yandex transmits a "hash of the hardware serial number and Mac address". Both also appear to send web page information to servers that "appear unrelated to search autocomplete". The researcher logged all network connectivity on the devices the browsers ran on. Chrome connections using QUIC/UDP had to be blocked so that the browser would fall back to TCP. To inspect encrypted data, mitmdump was used and since leftovers can be an issue, extra care was used to delete all traces of previous installations from the systems. The test design was repeated multiple times for each browser. [LIST=1] [*]Start the browser from a fresh install/new user profile. [*]Paste a URL into the address bar, press Enter, and record the user activity. [*]Close the browser and restart, record network activity. [*]Start the browser from a fresh install/new user profile and monitor network activity for 24 hours. [*]Start the browser from a fresh install/new user profile, type a URL and monitor traffic. [/LIST] [B]Closing Words[/B] The researcher analyzed the default state of the browsers and found that Brave had the most privacy friendly settings. At least some of the browsers may be configured to improve privacy by changing the default configuration, e.g. disabling autocomplete functionality. [/QUOTE]
