[edit]Panel Toolbar [edit]Break On All Errors

As with some of the other panels the console panel offers a "Break On ..." feature. In this case it's "Break On All Errors" (), which means that as soon as an error occurs the script execution is stopped.

[edit]Clear

Clears the console by removing all messages from the output.

[edit]Persist

This option prevents clearing the console when a page is reloaded. Thus all messages will stay inside the console as long as this option is enabled.

[edit]Profile

Enabling this option lets you profile JavaScript activity. For more info about this feature see theProfilingsection.

[edit]Filter buttons

There are different buttons allowing you to filter the display of messages logged to the console:

Option Description All Displays all messages Errors Limits the display to error messages Warnings Limits the display to warning messages Info Limits the display to info messages Debug Info Limits the display to debug info messages Cookies Limits the display to cookie events

You can also select multiple filters by holding downCtrl/
