It's not totally clear to me what you mean but I assume you are talking about AJAX requests being logged to the
Console panel. And I also assume that you were automatically switched to the
Firefox DevTools, because Firebug does not have Net, CSS, and JS in it's
Console panel and it doesn't work anymore once multi-process Firefox is enabled. See more about this in the
related Mozilla Hacks post.
So, to see the AJAX requests you can either switch to the
Network panel or click the little arrow besides the
Net button an check
XMLHttpRequests (XHR) from the popup menu. Within the DevTools Console you may even be able to see debug output logged to the console directly via the
Server filter. For this to work, you need to
add a script to your ColdFusion sources. I didn't try that out with ColdFusion myself yet, though.
For further information regarding the transition to the Firefox DevTools, see the
migration guide on MDN.
