Is there an add-on to view the source of CURRENT on an HTML page after activating AJAX components?

Question

In Firefox (Windows), when viewing a source from a browser, it will not update the source on the page if some AJAX components have changed. For example, you go to a page and it fully loads.

The AJAX component starts and modifies the source code, but if you click on the view source after this event, it will not be registered. If you download the HTML file and then view it in an external program, it will display the change.

Is there a way to quickly view the current source?
