Hello,

I noticed that the PWB users in our organization have been seeing a certificate warning popup when they perform a Google search from a few days ago.

I downloaded all root CA and subordinate CA certificates from the Google Trust Services repository (https://pki.goog/repository/) and installed them to the local machine certificate store, but the SSL certificate warning popup does not go away.

Edge and Chrome installed on the same machine do not give me the SSL certificate popup while displaying the Google search result (it shows that the Google WR2 certificate has been used to encrypt the search result).

How can I add these certificates to PWB?
Does PWB use the SSL certificates that are installed on a location other than the Windows local machine certificate store?
