Is it possible to disable form autocompletion in Firefox 4 but only for secure sites?

In general I want to use the autocomplete function but I don't want it to remember my credit card numbers. I just want to disable the feature for https sites.

Firefox 4 should use an algorithm to check form data for the presence of a credit card number and prevent it from getting saved as form data. So you can try to check if that works in your case.
