Hi,

I was able to reproduce this issue on Windows 10 with Firefox version Nightly 74.0a1 (2020-02-04) (64-bit) - Beta 73.0 (64-bit) - Release 72.0.2 (64-bit). Marking those flags as affected.
Also I'm setting status to NEW and component to Toolkit - Safe Browsing for someone to take a look at this.

Thanks you .Sorry for this disgusting picture .but any another website I have seen Firefox can't report some website.

Still not fix.This website you can't submit as Deceptive side.This website do not allow Firefox.

This bug happens because when we report deceptive site, Firefox tries to close the original website and then switch the reporting page.
However, the website calls setTimeout to change its window.location.href before unload (onbeforeunload), the network request to the reporting page is then canceled. The URL is set to the new URL in the settimeout function.

POC is here: https://dimidl.github.io/bug/bug_1612533.html

I know that Paul has been dealing with evil traps maybe he has come across similar problems and can help us out.

Paul, have you seen something like this before?

Yes, this has been an issue for a while. Bug 1263100.
Prevents the user from both navigating via the url bar and reporting the site via the menu. Requires user interaction to work though.
