You need to update your list of supported browsers.
There are several issues here.
- Netscape is no longer made by anyone, as stated in this announcement. The most important statement there is "We'll continue to release security patches for the current version of the browser, Netscape Navigator until February 1, 2008", which means that on 2008/02/02 it became a liability to use or recommend the Netscape product. You, as a banking institution, should be concerned about giving advice (browser to use) that if followed could lead to account hijacking.
- Microsoft no longer makes nor supports an Internet Explorer browser for Macintosh.
- Apple no longer makes hardware capable of running OS 9.
You should be recommending Mozilla Firefox, as does Netscape/AOL, for non-Windows users of the Macintosh, Linux, Unix, and (Free/Open/Net)BSD varieties. Having such outdated information on your website makes you appear to be "behind the curve" on technology and does not garner confidence in future customers. That is a real shame considering that I, as a computer engineer in the internet industry, am very impressed with the display of technology found with Bank of America. The statement made outside your site does not reflect the excellent user experience that is to be found inside.
