I have 5 hidden input fields in a form that I'm processing in jquery with $('#some-id').val(); which works fine in Firefox with Firebug not installed (and also other browsers).

However if I have Firebug installed it deletes some of the values of the hidden input fields and some get mixed up, seemingly at random. It works fine if I change the input fields to text fields, but obviously I don't want that.

Anyone else come across this problem?

Is there a way around this? Most users won't have firebug but some might and I don't want to rely on that.
