Is Fooman Speedster Advanced right for my store?

Fooman Speedster Advanced is a free extension which has been tested with the default Magento themes. However, there is always a risk that minifying and combining Javascript files can produce Javascript errors.

We do not recommend using Fooman Speedster without thorough testing on a test site if:

• Significant Javascript customisation work has been done on your store and the added non-default Javascript files do not follow best practice Javascript (you can test with http://jslint.com/)
• Your store already contains minified files
• Your store uses Jquery (or has extensions installed which use Jquery) - although a workaround is provided, almost 100% of reported errors are from stores which also use Jquery
