Unknown error ...
I'm getting an error message in the error console using the FF browser.
Where do I look to find out what this error means?
Error: uncaught exception: [Exception... "Cannot modify properties of a WrappedNative" nsresult: "0x80570034 (NS_ERROR_XPC_CANT_MODIFY_PROP_ON_WN)" location: "JS frame :: chrome://global/content/bindings/autocomplete.xml :: onxblpopuphiding :: line 825" data: no]
It does not point me to a line number in the HTML that I'm using (it only has 609 lines).
Obviously I can ignore the error by not looking at the error console
and it does not seem to be effecting the operation of the code
as all other actions seem to be working fine, but it's starting to bug me
and I don't like unknown bugs or "exceptions".
Has anyone received this type of error before and what did you do about it?
I found a posting where you can reproduce the error in a couple lines of code (see answer 3 I think it was): http://stackoverflow.com/questions/1...t-seem-to-work
I couple of other things that came up in my quick search seemed to have to do with either popups (either blocker add-ins or in browser blockers) or some sort of native library being called from within the browser. Seems there was also a bug a number of years ago for the engine used in FF that would throw that error if the DOM hadn't been built in a child window before running DOM methods (such as using innerHTML to populate a div and then using child collections on the div later). Don't know if that might give you a starting point to find where your error might be. Another thought is to check another install of FF (without any add-ons if possible) since the error might be something completely unrelated to your actual code.
