Is Speedster right for my store?
Fooman Speedster is a free extension which has been tested with the default Magento themes and successfully installed on thousands of Magento stores. 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:
- Your store already contains minified file
- 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 www.jslint.com)
- Your store uses Jquery (or has extensions installed which use Jquery) - although a workaround is provided in the instructions, almost 100% of reported errors are from stores which also use Jquery
