Because of their unfamiliarity and ability to encode arbitrary untrusted content in a URL, they are widely being used in spoofing and phishing attacks. Another problem is that they can be passed along without a backing page that runs JavaScript (e.g. a data URL can be sent via email). For that reason, Chrome, IE and Edge block top-frame navigations to data URLs. I do not understand why it does not Firefox.

I think this more ties into the decision about whether to allow top-level window data: URLs. I believe Christoph is looking at that.

Actually, I think this is just a duplicate of bug 1331351. We are currently waiting on telemetry data to come back before we make the decision.
