Security Issues

[Yoyo98cat]

Hi!
I'm a lawyer in spain and using firefox as a main browser to do any paperwork with the gouvernment.
Some weeks ago, the new update came in and most of the spanish institutional websites (https://sede.agenciatributaria.gob.es/Sede/inicio.html ; https://sede-tu.seg-social.gob.es ; etc.) are giving me warnings about security breaches. And I do have to keep "allowing risks and continue" to log into the website.

I've scanned several times my PC and no virus in sight. I'd like to know if it is a known issue or it might be some kind of other trouble i'd be just getting myself.

Special thanks to all developers contributing to that great project that mozilla is, y'all are nuts ❤️ ❤️

Hi,

I can't reproduce the issue with these websites, I asked a friend in Spain and this is working for him as well. What version of Firefox are you using and on which  platform? Does it happen just on going to these addresses or after logging in to the websiter with your credential? Thanks

Hi!
I'm using the firefox 126.0 64 bit for windows on windows 10.
The issue shows up when I try to log in. In the 2nd link, when i click the first option to log in, I get that screen in attatchments twice

Does it work in a private window? (that would mean it's an issue with the profile). Is you OS clock correct? This could cause this issue in my experience.

It works for me. Check the date, I see that the certificate is valid today.

Any Idea?

I don't understand why it shows you: "Verificado por: No especificado"

and me: "Verificado por: FNMT-RCM"

if I check it with another tool I get ‘Issuer: FNMT-RCM’.

Yeah, it's so weird. And frustrating... hard to work efficiently LOL

Based on what you've said, I would try rebuilding the certificates database to see if the problem originates there.  To do that:

1. Close Firefox if open.
2. Click the Start button in the taskbar, type %localappdata%\Mozilla\Firefox\Profiles and press the Enter key.  Alternatively, copy/paste the path to the (Windows key and R) Run box.
3. When the Profiles folder opens, double-click the folder for your Firefox profile.  If you don't know which folder that is, it will be the one with newest modification date.
4. Find the cert9.db (likely will appear as just cert9) file and either delete or rename it.
5. Restart Firefox and try again.

You could try to repair Firefox and see if that fixes your problem:
