Hi, I am loading an URL to the browser in a separate thread . While launching the url using attached code (nsTestImpl.cpp) i am getting the following error !!!!! XPConnect wrapper thread use error... XPConnect WrappedNative is being accessed on multiple threads but the underlying native xpcom object does not have a nsIClassInfo with the 'THREADSAFE' flag set wrapper: [object nsXPCComponents @ 0x833af60] JS call stack... 0 [native frame] 1 anonymous(aWebProgress = [xpconnect wrapped nsIWebProgress @ 0x86d4d68], aRequest = [xpconnect wrapped nsIRequest @ 0x88a6a80], aStateFlags = 458753, aStatus = 0) ["chrome://navigator/content/nsBrowserStatusHandler.js":175] nsIWebProgressListener = undefined nsIChannel = undefined ctype = undefined msg = undefined channel = undefined location = undefined kErrorBindingAborted = undefined kErrorNetTimeout = undefined this = [object Object] this.defaultStatus = "" this.overLink = "" this.jsStatus = "" this.jsDefaultStatus = "" this.status = "" this.securityButton = [object XULElement @ 0x87356d8] this.isImage = [object XULElement @ 0x872a2c0] this.statusTextField = [object XULElement @ 0x86a3dc8] this.stopContext = [object XULElement @ 0x8729cf0] this.stopMenu = [object XULElement @ 0x8729828] this.stopButton = [object XULElement @ 0x8621200] this.statusMeter = [object XULElement @ 0x87317f0] this.throbberElement = [object XULElement @ 0x86b0908] this.urlBar = [object XULElement @ 0x865b848] 2 [native frame] Please do help me to solve the problem.
