Firefox and Grid Certificates

Grid Certificates

You will need to have a p12 file of your grid certificate to load into your browser. The recommended browser to use is Firefox.

  • Click on OK when done

Check Your Certificate (if you have them)

  • Select the tab "Your Certificates"

  • Check the validity date
  • Close
  • If Validity is expired, delete that certificate
  • Click OK
