Brave, Mozilla Firefox, Google Chrome and Microsoft Edge presented on our current privacy work at the Enigma 2020 conference in late January. The talks were mostly high-level, but there were a few feature-level slides for each browser.
My ~10 minute presentation on Microsoft Edge was first, followed by Firefox, Chrome, and Brave.
At 40 minutes in a 35min Q&A session starts, first with questions from the panel moderator, followed by questions from the audience.
