Electronic certificate not detected in browser

Hi. I don't normally have a problem presenting my Spanish tax online, using an electronic certificate.

However, yesterday I got the following Error 403 message (in Spanish) : "Identification error. Electronic certificate is not detected or has not been selected correctly. If you have an electronic certificate, check that it is correctly installed in the browser"

I have checked that the certificate is loaded on the browser, that it is valid, and I have validated with the FNMT, which reports that it is working normally, so, why does my browser not recognise/detect the certificate.

Without resolving this issue I cannot make my tax declaration.

I would really appreciate any suggestions, please

Thanks Dropa.

I got support from the Tax Office, which told me to access the Firefox certificate store from the browser menu -- "Options", "Privacy and security", "Security", "Certificates", "View certificates".

Click on the "Authentication Decisions" tab. Locate the ones corresponding to "agenciatributaria" and delete them, taking care not to delete any certificates.

This worked for me, just in the nick of time!
