Bug 204775 – Web Inspector: provide a way to log messages from the network process

• Status: RESOLVED
• Resolution: FIXED
• Component: Web Inspector

[Devin Rousso]

This could be used for ITP and AdClickAttribution debugging to start, rather than requiring the developer use Console.app and filter for specific channel names.

We should also add items to the device settings menu for ITP and Ad Click Attribution debug logging so that they can be controlled when remotely inspecting.

We should consider only sending a message to already open inspectors, so that messages aren't shown if an inspector is attached to a tab way later since messages are cached.

r=me. Per our discussion, the approach looks good, but need to fix tests that are failing EWS.

Please rebase so we can land it.

This looks good, but you should consider adding a SessionID as a parameter and only broadcasting to web processes with the same session id.  Otherwise you'll be sending private browsing logs to regular browsing pages and vice versa.

Good point!  Thanks for taking a look :)
