This is a pet peeve.
Every other message board that I visit allows Firefox's "remember form entries" feature to work. So when I land on some other board's login screen, my user name and password are automatically populated.
Chowhound has to be different. You guys pop up an overly programmed, clever little CSS based box that contains the user and password fields. Firefox does not fill these in, ever, so I have to type it in, and I usually get it wrong.
Also, this new release has a Firefox related bug. That klever little CSS floating login form does not get dismissed when the username/password has been accepted. So I have to manually refresh the entire window to make it go away.
I suspect that there is someone there at Chowhound who felt compelled to be creative and unique with the login feature, but I say it is a poor implementation for these reasons.
Keep the login form on the page without the popup form malarky so that the browser's convenience features for form fill-in work as expected.
