I wish they included a bit more information on the bug's severity. I've been using Safari on macOS, and this might make me seriously consider dropping my usage entirely in favor of Firefox. What we need is stronger website isolation and permissions. Depending on the site's functionality and how frequently I use it, I'll modify their permissions. Some browsers allow you to restrict a couple features, but I'd argue it's not granular enough. Why should any random site be allowed to use WebSockets, WebRTC, WebGL, etc? I'd want to turn off all those features and more on sites that I don't think should have them. I'm actually a bit annoyed with Safari 11, which removed the ability to conditionally disable WebGL. In my experience, most websites that were using WebGL had absolutely no good reason to do so.
