How can I distribute SonicWall DPI-SSL CA certificate to web browsers?

In MS Windows, Internet Explorer, Chrome, Opera browsers share the system certificate store. When a CA certificate is imported as a Trusted Root CA into the local machine store or the local user store, any certificate signed by the CA is trusted by these browsers. This can also be done using the Microsoft Certutil command-line utility with the following command:
certutil -addstore -f -enterprise -user root dpi-ssl.crt > NUL
The process can be automated via Group Policy and other such means. Refer this KB article for a detailed description of the process using Group Policy:

Mozilla Firefox, on the other hand, has its own certificate store and Root CA certificates must be imported manually into this store. Alternatively, this can be done using the NSS Certutil utility with the following command:
certutil -A -n "CN=SonicWall Firewall DPI-SSL" -t C -d C:Users<username>AppDataRoamingMozillaFirefoxProfiles<first-part-of-the-name-of-the-folder>.default -i dpi-ssl.crt
The above command assumes
- You are either running certutil.exe from its folder or certutil is a global system variable
- The name of the profiles folder varies with each PC
- The name of the SonicWall DPI-SSL certificate is dpi-ssl.crt
