Most browser-based banking sites will require Javascript, and will often go through several layers of redirect. One of the goals of these mechanisms is to try and ensure that no significant information gets left lying around in browser caches and/or local proxies.

Another goal is to try and ensure that credentials are input by a human being. This is an attempt to prevent the possibility of root kits and other nasties from being able to login automatically. The single greatest point of weakness of the entire banking system are customers homes. Most banks do everything they can to prevent automated access to their systems, other than via those mechanisms they put in place.

For the record. I have *no* associations or relationships with Chase. And I do not use internet banking systems. The only online banking systems I consider secure are those that use dedicated dialup. Paranoid? Make up your own mind.

As for me "losing it". Is it really such a stretch of your imagination, that the breadth and depth of the skill levels in this place, combined with the freely given nature of that expertise, has not gone unnoticed to those on the web that would put that expertise to less than legitimate usage?
