I am using a client certificate to authenticate against some Apache HTTPS website.

By default, Firefox 3 has a very annoying setting : it will prompt you with a box to select your certificate, every time the browser access to a file.

I quickly realized that there is not setting in the preference tab to change this behavior. That sucks, really !

Fortunately, it is possible to tweak it within the about:config page. Set the security.default_personal_cert entry with Select Automatically instead of Ask Every Time.

But what a dumb behavior !

It is like the alert page that Firefox displays every time a self-signed certificate is used. I am now wondering if the developers really understood well what a certificate is !
