A study from 2020 found Edge to be the worst browser when it comes to privacy, in a separate category of privacy invasion shared only with Yandex the Russian browser. > From a privacy perspective Microsoft Edge and Yandex are qualitatively different from the other browsers studied. Both send persistent identifiers than can be used to link requests (and associated IP address/location) to back end 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. https://www.scss.tcd.ie/Doug.Leith/pubs/browser_privacy.pdf https://www.scss.tcd.ie/Doug.Leith/pubs/browser_privacy.pdf
