How to import a valid copy of your electronic certificate

Windows-Import copy of the certificate in Mozilla Firefox

To import a certificate in Firefox, you must have completed the copy with a password, since to install it in this browser, you must enter the "backup password." In addition, the copy must have been made in a valid format. The icon of a valid copy will be an open envelope with a certificate peeping out and a key, and the extension .pfx or. p12. If the extension is not visible, right-click on the certificate icon and go to "Properties."

In Mozilla Firefox, go to "Open the application menu" (three-line icon located in the top right corner of the browser), "Settings" or the "Tools" menu, "Settings."

In "Privacy and security," Security, "Certificates," click on the button "See certificates."

In the tab "Your certificates," click on "Import...."

Select the file containing the copy from the location where it is saved and click on the "Open" button in the "File certificate to import."

The browser may request the master password (it is the password of the Mozilla Firefox certificate store and by default it does not set; If you decide to set it up, please note that its forgetfulness can cause the certificate to be lost). If there is no established card, you can leave it blank, but if you have already set it up, you will have to enter it in order to continue with the import of the certificate. If no message appears on the master password, go ahead.

A new window will ask for the password used to encrypt the backup copy. Accept.

If everything is correct, the certificate will appear in the Certificate Manager window, in the "Your certificates" tab.

If the copy is not valid, when importing it, it would be installed in the "People" tab instead of in the "Your certificates" tab and the certificate would not be valid for working on the Tax Agency page.
