How to add SSL Certificates to PWB

[hokazaki]

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?

Public Web Browser version 3 (PWB v3)
Version 3.20.04 03-27-2025
OS Name: Microsoft Windows Server 2022 Datacenter
OS Version: 10.0.20348 N/A Build 20348

In PWB version 3.20.07 10-28-2025, the handling of SSL certificates was changed to match Edge and Chrome.

Fixed/Changed:
Fixed default handling of SSL Common Name Incorrect.


Up grading to the current version of PWB will correct it.

Hello Scott,

Thank you for your reply.

I downloaded the "PWB x64 Edge Upgrade Only" zip package (Version 3.20.08 12-11-2025) and overwritten the four files (INIUpdate.exe, libpwb.dll, PWB.exe, WebView2Loader.dll) with the downloaded ones, but I'm still getting the same certificate warning popup when I perform a Google search.
Is there anything else I should check?

You can force it with the following setting in your INI file.

[Security]
DisableSSLNotification=True

--Scott

Please send a copy of your INI file as an attachment to the support email. Perhaps there is a configuration issue.

You can check this by downloading the PWB distribution and running it with an unedited INI file.

Hello Scott,

Thank you so much for your reply.

I added the line
DisableSSLNotification=True
to the Security section of the PWB.ini file and suppressed the certificate warning, but would like to find the root cause, if possible.

I attached the PWB.INI file.
I appreciate your help.

Are you just typing in google.com or is there a link that is being clicked.

Using PWB 3.20.08 and your INI file, we set the following and do not see the SSL error.

[Browser]
HomePage=https://google.com

[Security]
DisableSSLNotification=False
