Attention: Start of changeUnless client customizations are explicitly coded for multiple browser support, they might not work in Firefox. Avoid using functions only supported by a particular browser in your customizations; for example, using document.all() (an Internet Explorer function) in a customization would cause the application to fail when running it in a Firefox browser.
