Hi Everyone, Yoshi asked me about first-party isolation of various kinds of top-level content, including: data:, chrome:, resource:, about:, javascript: URLs. Should Mozilla generate first-party "pseudo-hosts" for these as we have in Tor Browser? What are the pros and cons? Here's the bug -- feel free to comment directly: https://bugzilla.mozilla.org/show_bug.cgi?id=1300671 Thanks, Arthur
