This is normal behavior. Unfortunately, this causes a bunch of "Failed to load resource: cancelled" errors in the console. Setting an onabort handler doesn't make a difference. Wrapping abort() into try..catch doesn't either. Example: var xhr = new XMLHttpRequest; xhr.open('GET', 'http://www.google.com/'); xhr.send(); xhr.abort(); // www.google.com Failed to load resource: cancelled 261191 1 ap 2010-08-06 04:30:27 -0700 Yes, we probably shouldn't be logging the cancelled error. 365142 2 caseq 2011-03-10 06:55:47 -0800 *** This bug has been marked as a duplicate of bug 55764 ***
