I have sometimes observed this on an existing profile as well, so it may be worth investigating, see related bug 1146976 which happened some time ago. This might not depend on us but on the Safe Browsing service, though. The issue with new profiles is well-known, and it happens because the full Safe Browsing lists haven't been updated yet. Since our QA is often stumbling on this issue, see bug 1299170 as example, is there a way to set up our own test URIs that are hardcoded in the client? In fact for the Downloads Panel we just need to test the verdicts, in particular malware, potentially unwanted, and uncommon downloads.

We wrote a support page to let users manually update Safe Browsing list in about:url-classifier. You will see some update button, if you want to test malicious warning page, just click update before your test.

What Thomas said is true in general (and for V4 that's all we'll care about), but for V2 (Fx <= 55), there is an extra complication: it takes up to 14 hours for the entire list to be downloaded. So because the first test of the "Download Warnings" section is based on URL blocking (as opposed to the contents of the download), then if you're using a new profile, you need to first leave it running for 14 hours before running through the tests. After that, it should work fine. All of the tests should pass.
Thanks for the explanation, the 14 hours running time is probably the reason for the issues with the first download I observed in existing profiles. Since this is not an issue anymore in Firefox 56, the most common reason for which QA thinks something is broken in the client could be gone. Maybe we should just leave this bug open as reference for QA until 56 is released.
