Useful, but logs an error to the dev console on every click.
TypeError: event is undefined, content.js:10:6

Edit: Updated rating. Not getting error anymore. Thanks for the fast fix.

Hey, this is a great plugin for people like me working on M2M communication. Is there any chance that you could add support for timestamps in milliseconds?

Update 11/03/23: thanks for the update. Could you also add support in the textbox displayed when extension icon is clicked?
