import_root_cert

Imports *.cer file specified in command line to Mozilla and Opera CA storages. If no file name is provided, it searches for a first *.cer file in the same directory with executable. The tool scans user profiles, searches for certificate database files by name and adds the specified root certificate to storage if necessary.

certutil.exe with dependencies is used for updating Mozilla certificate storage. These files must be stored in "nss" subfolder in the same directory with executable. 

Example: 
import_root_cert.exe NetFilterSDK.cer
