Chosen solution

The issuer of the certificate is your Adguard software

Subject: C=US, ST=California, L=Mountain View, O=Google Inc, CN=www.google.com
Issuer: C=EN, CN=Adguard Personal CA

You will have to install the Adguard root certificate in the Firefox Certificate Manager.

You can also export this root certificate in another browser that works and import this certificate in Firefox.
