[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 the Profiling section.
[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 |
