User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv: Gecko/2008070208 Firefox/3.0.1
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv: Gecko/2008070208 Firefox/3.0.1

The following error message appears (stochastically ?) in the error console when pages with HTML forms are processed:

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 834"  data: no]

No impact on the actual page can be noticed, though. (However, it is disturbing in getting my own JavaScript code clean. ;-) )

Reproducible: Couldn't Reproduce

Steps to Reproduce:
I tried browsing several pages of the web application I had been working on when the error messages appeared, but I could not provoke the error once more.

Sorry I was not able to reproduce the error. However, since it pertains to an uncaught exception, the reason why the exception occurred is probably less relevant than the fact that it was not caught.

The bug still exists in Firefox 3.6.10 (and any preceding 3.x version). It occurs whenever the autocomplete function offers contents for a form field but (different) contents are typed in. It appears not do do any harm to the operation of the browser or the page, but it is extremely tedious during debugging JavaScript code on web pages containing forms.

And, yes, it is apparently a duplicate of bug 428602.
