postMessage debugger

Thank you, very convenient for development process.

This extension is great! Use it a lot.

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,... Show more

This is not working at all 👎

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)"

very helpfull :)

Nice tool... works great

This works nicely and does what I need. Others have mentioned setting "Verbose" in "Default Levels". It's also helpful to choose the appropriate context from the pulldown (just to the left of the eyeball) in the top bar of console.log Suggestions for improvement, if you have time: 1) log the postMessage events from / to all contexts, not just the chosen one. 2) use some sort of log level that doesn't require messing with Default Levels, if possible. These things would make it easier for me ... Show more

Convenient tool! I was about to write one, it saves my time. For guys not seeing the log, Check 'Verbose' in Console tab's top bar 'Default levels'

Works as advertised (logs to debug, so make sure to set console log level to Verbose). Inspected the source code on 8/22/19 and as of now it's not doing anything malicious (no file downloading, no posting your data, no analytics tracking). Thanks for a very helpful tool!
