I wanted to see if other browsers would be interested in joining us on this adventure. Hi Emily! Brave Desktop tries to address this issue by showing the origin of the download in the downloads bar at the bottom of the browser and a little red insecure icon next to HTTP. Our designers are not a fan of this approach since it adds ~10px to the download bar height and looks a bit cluttered :).

We're still finalizing our metrics before we can share them publicly, but right now it's looking like it will be feasible to block a set of high-risk filetypes (executables and archives as determined by the Content-Type header or sniffed mime-type). We will likely focus on protecting desktop users because Android and Safe Browsing already provide protection against malicious APKs. > I think this is a good idea in terms of user safety but more questionable in terms of the incentives for developers to migrate to HTTPS, as Dev stated. If Chromium has a heuristic for high-risk filetypes, Brave would strongly consider blocking files matching that heuristic over HTTP regardless of the context. > We're not planning to focus on non-secure downloads initiated from non-secure contexts at the moment, because users at least see the "Not Secure" omnibox badge on those pages. > > Feedback welcome! > Thanks, > Emily
