This tutorial will show you how to install your own SSL certificate. Such certificates are widely used for personal identification, for example, for online banking systems. The certificate ensures that the person connection is the one who should only have access to the system.
To get to the proper place you must go to the browser Options. You click on Tools menu then select Options
Once we have the Options menu opened we click Advanced. Then we go to Encryption tab.
Last steps are pretty simple as the steps so far. All you need to do is click on View certificates and then click Import. This will pop up and Open File dialogue box. You need to navigate to your certificate file and the open it. Firefox will prompt you to type the password for the Certificate and that would be all. The password for the certificate is yet another method for identifying that the certificate owner access it. This ensures that even of someone else has access to your computer and your browser it will be impossible for him/her to use the certificate even though it is installed on it. Any time you connect to the remote system that requires this certificate for identification you will be asked for the very same password.
