Why is Firebug reporting "Component returned failure code..."?

[Johnvey]

I'm running Firefox, and on certain dashboards, I'm getting the following error in the Javascript console:

Error: uncaught exception: [Exception... "Component returned failure code: 0x805e000a [nsIXMLHttpRequest.open]"  
nsresult: "0x805e000a (<unknown>)"  
location: "JS frame :: http://mrt:8200/en-US/static/@79191/js/contrib/jquery-1.3.2.js :: anonymous :: line 3517"  
data: no]

The dashboard doesn't seem to finish, and the green "Loading..." box in the upper right hand corner of the screen doesn't go away.

One common problem is if AdBlock is installed in your browser. AdBlock interferes with the XmlHTTPRequest object and is known to break the Splunk interface. The first step is to disable AdBlock for your Splunk hostname or globally in Firefox.

Nothing more with respect to AdBlock. It depends on what kind of AdBlock, and whether or not the URIs used by dashboards (which include saved search names) trigger a blocking filter.

Really, is there more to this? I have run adblock since forever. Are there particular symptoms to look for?
