The developer console is a tool which logs the information associated with a web page, such as JavaScript, network requests, and security errors. (It does other things, too, but this is all that really matters for this article.)
The information displayed in the developer console can be extremely helpful our support team when we're trying to figure out how to solve an issue. In the course of troubleshooting your issue, the Artemis support team may ask you to take a screenshot of the developer console.
