While this isn't specifically related to jQuery, it certainly could affect jQuery users, so I thought I'd post the link.
It appears Firefox 1.5 (and lower--I don't believe it exists in v2) has an internal bug with dynamically created <input /> elements and later invoking the focus() method on the field. It will occasionally throw the error "NS_ERROR_XPC_JS_THREW_STRING" and cause browser freezes. This apparently is a bug in the code relating to Firefox's native autocomplete functionality and can be worked around by adding the attribute autocomplete="off" to the elements. NOTE: This doesn't happen every time, it's a seemingly random occurrence. For more detail on the problem, see this link: http://www.activewidgets.com/javascript.forum.3865.1/finally-solved-ns_error _xpc_js_threw_string.html I'm posting this just because I'm sure I've seen this problem crop up from time to time and just never realized it was the culprit. I also thought this would be useful to other JS developers, since it's quite possible many of you are creating dynamic <input /> elements. -Dan
