  • (2020-08-17) Alberto Blacutt: Nice tool... works great
  • (2020-01-08) Oliver Jones: 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 to ask my customers to use it to troubleshoot message posting between iframes (mine) and parents (theirs). Again, thanks for this extension. It's really useful.
  • (2019-10-18) Pike96: 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'
  • (2019-08-22) Eric Eldard: 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!
