问题
This error triggers only sometimes when I do an XMLHttpRequest.
uncaught exception: [Exception... "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIXMLHttpRequest.setRequestHeader]" nsresult: "0x80004005 (NS_ERROR_FAILURE)" location: "JS frame :: file://.../Mozilla/Firefox/Profiles/.../extensions/.../components/greasemonkey.js :: anonymous :: line 1332" data: no
How can I fix it?
