4. On the Developer toolbar, click Debug. Available options include:

   - Enable Debug - Specifies the level of detail included when you click View Debug .

     - Off - Disables debug mode

     - Info (default) - The debug log contains the default or normal amount of information. This corresponds with a log `LEVEL4` and a Debug URL argument of `YES`.

     - App Trace - The debug log contains messages up to level 6. This corresponds with a Debug URL argument of `LEVEL6`.

     - Full Trace - The log will contain the maximum amount of information. This corresponds with a Debug URL argument of `LEVEL9`. Full Trace can slow request processing but provides the most amount of detail.

     If debug mode is enabled, debug data is captured in the background. As long as the browser tab or window stays open, uses the current debug mode and level.

   - View Debug - Displays debug information for the current page.
