There seems to be issue with Autocomplete/autofill feature. The issue was happening in both Firefox and Internet explorer. Many of website forms keep filling fields automatically and wrongly. It was filling user id/password automatically in incorrect fields.
The issue seems to be because of Norton as discussed here. You can verify it by disabling the Norton add ons in web browser. If disabling fixes the issue, here is what you can do. The issue seems to be with Norton Internet Security 2008. Install NIS 2009 and issue should be fixed. All NIS 2008 customers can install NIS 2009. The NIS 2009 should also be better, safer and faster.
