Possible errors in the use of the electronic certificate
Skip information indexYour certificate did not allow you to generate a valid signature in Mozilla Firefox
Verify that you have the appropriate root certificates and that you have marked all purposes in the trust settings of these certificates. To do this, access the Mozilla Firefox options or preferences from the browser menu (icon with three horizontal bars located in the upper right corner of the window). Within "Options" , enter "Privacy and security" , "Security" , "Certificates" , "View certificates" .
In the "Authorities" tab check that the corresponding root certificate is installed, depending on the type of electronic certificate that has been obtained. In this sense, keep in mind that:
- Since March 1, 2015, the natural person certificates generated by FNMT depend on the root certificate AC FNMT Users and are issued under FNMT -RCM.
-
Since October 2015, representative certificates generated by FNMT depend on the root certificate AC Representation and are issued under FNMT -RCM.
- Certificates generated before March 1, 2015 depend on root certificate FNMTClasse2CA and are issued under FNMT
Select the corresponding root certificate and click "Edit Trust" to check if the trust purposes are checked.
If the root certificate does not appear in "Authorities" it is necessary to download it from the FNMT page.
