How to test a flash detection script without uninstalling flash player?

I´m using the Flash Player Detection Kit. Is there a Firefox add-on, some plugin or software to toggle between Flash-Non F开发者_StackOverflow中文版lash for testing purposes of this script?

Go to Add-Ons->Plugins and turn off Flash.

The QuickJava extension puts an array of buttons in the FireFox status bar that lets you enable/disable flash, java, javascript, or silverlight.
