This does not seem to work on Firefox and IE10 (I haven't tested yet on other browsers). On Firefox (21) I get: [19:09:02.976] NS_ERROR_NOT_AVAILABLE: Component is not available @ file:///D:/Watermellon/scripts/base-classes.js:14 and on IE10 i get: SCRIPT16389: Unspecified error. base-classes.js, line 14 character 13 The files and their directories are: root/index.html root/scripts/base-classes.js root/images/logo.jpg Now when I change the img.src to a URL (an image from another site) everything works fine, the image draws itself after a delay(for it's get from the url).

To figure out what failed, look for the origination function. For example, in: [Exception... ns error "Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIDOMHTMLSelectElement.selectedIndex]" nsresult: "0x80004005 (NS_ERROR_FAILURE)" location: "JS frame:: ...it's nsIDOMHTMLSelectElement.selectedIndex, a good thing to google for. This particular error was caused by trying to set an out-of-bounds selectedIndex on a drop-down (and is an example from [1]). nsIXMLHttpRequest.* XmlHTTPRequest-related errors will usually occur in either nsIXMLHttpRequest.open or nsIXMLHttpRequest.send The specific error is often the ns error not best indication of the problem. The actual problem to fix (often in the scripting logic) is regularly one of: stale references, often between documents (think (popup) windows, frames, iframes, and embeds), or the browser got confused about when it should clean up. For example, if the document an XHR was created in does not exist anymore, or using an old reference to a new embedded plugin object (e.g. video) that you violated the specs or did something nonsensical, e.g. trying to send() more than once(verify) or trying to set headers after sending data (verify) Use of firebug: If you are using firebug, you should be aware that there are older versions that did not handle XHR in frames well. Firebug would be the sole cause of the last mentioned error. triggering XHR from the firebug command line is sandboxed, and may cause this in certain cases trying cross-domain XHR, or using an absolute URL (verify) You could even look at the Firefox XHR source code, e.f. for send(), to see what cases trigger this error.

Each error is listed by its name and an error code in parentheses. An error will typically be displayed on the error console, but can be captured using a try-catch block in JavaScript. These constants can be accessed through Components.results. For example, by using Components.results.NS_ERROR_NOT_INITIALIZED General Errors The following errors are general and can occur when using any component. NS_ERROR_NOT_INITIALIZED (0xC1F30001) An attempt was made to use a component or object which has not yet been initialized. These components usually provide an initialization method, often called Init, which must be called before other methods are used. NS_ERROR_ALREADY_INITIALIZED (0xC1F30002) An attempt is made to initialize a component or object again which has already been initialized. NS_ERROR_NOT_IMPLEMENTED (0x80004001) This error is caused by methods which are not implemented. This could occur because the implementation has not yet been written, or because the component intentionally does not support the desired feature. NS_ERROR_NO_INTERFACE (0x80004002) An attempt was made to call QueryInterface to retrieve an interface which an object does not support. NS_ERROR_NULL_POINTER (0x80004003) An error occurred because a value was set to null when this was not expected. NS_ERROR_ABORT (0x80004004) This error indicates that an operation failed and the caller should abort whatever action is being performed. This typically will occur if an operation could not complete properly. NS_ERROR_FAILURE (0x80004005) This is the most general of all the errors and occurs for all errors for which a more specific error code does not
