此错误仅在我执行XMLHttpRequest时触发。
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
我该如何解决？
