Luca, we are facing one issue here. When we handle the `http-on-stop-request` even for blocked request - the request doesn't seem to have nsILoadContext associated. Here is how we get the context: https://searchfox.org/mozilla-central/rev/7d0c94a0e9a9fe1f83553f49b10128567d21709d/devtools/shared/webconsole/network-helper.js#248 We need the context to get the top frame (or parent window where the request is executed): https://searchfox.org/mozilla-central/rev/7d0c94a0e9a9fe1f83553f49b10128567d21709d/devtools/shared/webconsole/network-helper.js#217 The top frame/parent window is used to figure out whether the request belongs to the debugged tab (where the Toolbox is opened) and whether we should display it in the Network panel. here is the `matchRequest` function implemented: https://searchfox.org/mozilla-central/rev/7d0c94a0e9a9fe1f83553f49b10128567d21709d/devtools/server/actors/network-monitor/network-observer.js#102 Do you see a way how to solve this or does this need a platform change?
