Search on Google sometimes doesn't work
In the past few days every now and then when I use the firefox bar to make a search firefox tells me that it can't build a secure connection with google.com. Basically firefox doesn't trust www.google.com. I can't update a screenshot because right now it isn't happening.

What are the exact error message(s) ?
Sorry if I kept you waiting but the error took a little while to pop up again. Here it is.
Hi richiba00, if you click the Avanzate button, what is the error code? Usually it is in all caps with underscores: SEC_ERROR_SOMETHIING
This article describes various common causes for various of the errors, but since you get this intermittently, it sounds suspicious:
The error in this instance is SEC_ERROR_UNKNOWN_ISSUER. Also I get errors only using Firefox and not others browsers, I tried Chrome and Edge for at least a couple days and they worked just fine.

When you are getting the error, that code is a "link" that reveals a coded version of the rejected certificate. You can copy/paste that here and a support volunteer will decode it, or you can use an online decoder. The critical thing usually is the Issuer.

Here is the certificate

Hmm, that doesn't match the one I get. The reported issuer is:
DigiCert Global Root G1A
while the one I get has this issuer:
Google Trust Services
and the upstream issuer is GlobalSign, not DigiCert.
So I suspect a "man in the middle" is attempting to use a fake certificate to monitor your searches, but I don't yet have a lead on what is behind it.
Do you notice the problem during certain times of day, or after other events on the computer? Any pattern to it?
I don't know whether you have a preference, but does google.it work?
The firste time I noticed this google.it worked, now it doesn't. I didn't noticed if the error occurs after a particular event but I'm sure it showed up only between 6 PM and 12 AM CET.
Perhaps it would be worth running some malware scans. The following article lists tools that are free or have a free trial:
