Description
This API method allows script authors simple access to logging informational messages in the Error Console.
If you aren't seeing your messages, make sure you navigate to about:config, and change the values of javascript.options.showInConsole and javascript.options.strict to true. This can be helpful for debugging.

Examples
GM_log and Firebug
Since Firebug 1.0, extensions.firebug.showChromeMessages must be set to true for GM_log messages to show up in the Firebug console.
It is also recommended to enable extensions.firebug.showChromeErrors, as doing so will reveal syntax errors and script breaks.
This can be done from about:config, or from the Firebug GUI. Go to the "Console" tab, then click the arrow next to the tab's name, and ensure that "Show Chrome Errors" and "Show Chrome Messages" are checked.
