Alert when PUX is enabled that a local replay is required first in DejaClick Firefox

The option to enable Perceived User Experience does have a 'What is This' link and does indicate that additional charges are consumed when it is enabled in 1.0. Seems like it would be a good idea to let users know that a local replay is required as well, in Firefox, with this option enabled, before the metrics will be accurately reflected in reporting at AlertSite.
