Hey Sunil, I've taken another look to provide more information. So looks like we hit:

[Parent 93097, Socket Thread] WARNING: NS_ENSURE_SUCCESS(rv, rv) failed with result 0x804B005D (NS_ERROR_LOCAL_NETWORK_ACCESS_DENIED): file /builds/worker/checkouts/gecko/netwerk/protocol/http/nsHttpConnectionMgr.cpp:1591

and navigation to "http://127.0.0.1:55946/support.html?topic=phishing-malware" times out.
That seems to be happening when we:

Looking at the bug 1972350, not sure if we should set now some extra permissions. Could you help us here?

Hey Sunil,
I've seen that you removed needinfo, did you not find anything?

Comment 21

[Sunil Mayya]

Hey Alexandra,

I've seen that you removed needinfo, did you not find anything?
Sorry for missing this, it was by accident.

We have introduced LNA feature recently and any navigation to localhost (127.0.0.1) would prompt user for permission.
My guess is that we are experiencing timeout because the request is waiting on the user prompt.
Can you please confirm this?

I did not reproduce the issue locally, please let me know if you want me to have a look at it further.

Comment 22

[Alexandra Borovova [:Sasha]]

Attachment: Screenshot 2025-08-08 at 11.52.03.png

I don't see the prompt :( The navigation is just pending. I've attached the screenshot from the test in case I'm missing something.
In case you want to run the test locally, not sure if you've seen that the test is disabled now. To enable it again, you need to remove this metadata: https://searchfox.org/mozilla-central/source/testing/firefox-ui/tests/functional/safebrowsing/manifest.toml#15-21.
