Digital Certificate from Firefox

While IE, Chrome, Safari/iTunes, Outlook, etc. use Windows' certificate store,

Firefox and Thunderbird use NSS' cross-platform certificate store. Opera also uses its own separate certificate store.

In Firefox

about:config Navigate to:

security.enterprise_roots.enabled

and set it to true.

Now

Open Firefox File Location.

 

Go to defaults\pref\ folder and create a new file with the following

/* Allows Firefox reading Windows certificates */    

pref("security.enterprise_roots.enabled", true);

Save it with .js extension, e.g. trustwincerts.js and restart Firefox. The entry will appear in about:config for all users.
