From a study conducted by Douglas J Leith from the School of Computer Science & Statistics at Trinity College Dublin, Ireland, they found that the new chromium based Edge is sending hardware UUID's back to Microsoft and there isn't an option to turn it off. "From a privacy perspective Microsoft Edge and Yandex are much more worrisome than the other browsers studied. Both send identifiers that are linked to the device hardware and so persist across fresh browser installs and can also be used to link different apps running on the same device. Edge sends the hardware UUID of the device to Microsoft, a strong and enduring identifier than cannot be easily changed or deleted. Similarly, Yandex transmits a hash of the hardware serial number and MAC address to back end servers. As far as we can tell this behaviour cannot be disabled by users. In addition to the search autocomplete functionality (which can be disabled by users) that shares details of web pages visited, both transmit web page information to servers that appear unrelated to search autocomplete." https://bgr.com/2020/03/11/microsoft-edge-browser-privacy-issues-performance/ https://bgr.com/2020/03/11/microsoft-edge-browser-privacy-is...
