Error: uncaught exception: [Exception... "Component returned failure code: 0x805e000a [nsIXMLHttpRequest.open]"

Have you ever stumbled upon this error: an XMLHttpRequest fails with the mysterious message

Error: uncaught exception: [Exception... "Component returned failure code: 0x805e000a [nsIXMLHttpRequest.open]"

The weird thing is that the same page works just fine in any other browser than Firefox/Mozilla. The solutions probably is: turn off Adblock Plus temporarily for the page. Worked like a charm for me. Hope this saves someone else some time...
