Browser Console logging
The Browser console logs the same sorts of messages as the Web Console:
• HTTP requests
• Warnings and errors (including JavaScript, CSS, security warnings and errors, and messages explicitly logged by JavaScript code using the console API)
• Input/output messages: commands send to the browser via the command line, and the result of executing them.
