I was pleasantly surprised that this reports messages sent to iframes as well as messages received by the top frame as well. As others said, if you don't see anything in the devtools console, you probably need to pull out the sidebar to look at the verbose/debug log level. A good example case is the youtube embed API (you can find examples on codepen). It would be very helpful if this logged a bit more information about each MessageEvent rather than just the data...like the origin, source, ports and lastEventId. Currently it seems to log the window title, but perhaps the window url or origin would be more useful.

2021-06-30 Edouard Lopez Work as expected and log event, but I wasn't able to toggle off the logging other than disabling the whole extension.

Very useful extension, but the thing about selecting 'verbose' in the Console's 'levels' box ought to be more prominent! It should be in the description of the Extension: "This extension prints messages sent with postMessage to the console (turn on Verbose levels to see them)"
