Ars Technica:

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.

Not exactly surprising.
