Perform while loop in the Selenium IDE

This extension provides goto, gotoIf and while loop functionality in Selenium IDE. The image below shows a sample test case using goto, gotoIf and a while loop, all running successfully in Selenium IDE. 

The file linked at the end of this post should be saved as "sideflow.js" to your hard drive. Then the Options settings in Selenium IDE should set the Selenium Core extensions to include the path of this file, similar to the image below.
