Auto fill and one bank acct will not work together
Auto fill and one bank account don't work together.
My logins mostly work, however when logging into my bank's url, I have to type in the acct # (equivalent of user name), then on next screen a security question, and a radio button to click on "This is a personal computer. Register it." On the next screen my password fills in and I click submit. The PROBLEM... 1) the acct # is not remembered (is this because it and the password are not on the same screen?), and 2) most troublesome, the system does not remember that I've completed the security question and checked the radio button - hence I have to go through the process on every login.

1) Every browser I have ever used handles a Username & Password on the same page, but that type of login procedure with the "username" on one page and the "password" is on another web page is non-standard. Until there is a W3C standard for that type of login procedure and all browsers can recognize it or use it, your bank is creating "problems" for their users. And if part of that procedure would work occasionally (I have one website I use that does it that way, and the "username" does auto-fill), the data being auto-filled is probably coming from the '"form history" part of the web browser (non-encrypted data), which is less secure than password data is.
2) As far as the "security question" problem, if that information is being stored in a "cookie", you need to figure out why that "cookie" is disappearing. Make sure Firefox is set to store all cookies until they expire and is not set to clear cookies when closing, and to make sure that you don't have a "security application" installed that is clearing your cookies after Firefox is closed.
