Is there a way to hide the \"XHR finished loading\"
messages in the console?
Yes, open the contextmenu in the console, and remove the check at Log XMLHttpRequests
.
You can still inspect the network traffic at the Network tab.
There is some workaround posted in chromium issue tracker http://code.google.com/p/chromium/issues/detail?id=15472
Which version of chrome you are using? In my console there is checkbox to enable or diable log XMLHTTPRequests I am using 17.0.963.79
