First Lets see how logs appear with default logging level. To check that open console either on Firefox or in Chrome. Here I am showing you chrome image in earlier post I have used firefox web console.
Now as you could see there are various logger statements available by default it you want to see only particular set of logs based on level you could do it through that option “Update Debug Logging Preference”.
Click on that and it will open up popup as shown below. Add you value and click Save.
It will filter out rest of the logs and will only show logs for widgets which meets given criteria in filter. Those filter are saved in user preferences.
With this we have explored one of the option available in the debug menu. Many more to follow in upcoming blogs.
