Please let us know the outcome

When did this start happening? Were there any changes prior to the issue?

For now, the best action we can take is to turn off the Warn about certificate address option in
Internet Options.

Follow these steps to do so:

• Press the Windows key and type Internet Options. Once it shows up, select it to open.
  
• Navigate to the Advanced tab, then browse to the Security
  section to find the Warn about certificate address mismatch option.
• Uncheck it and click Apply, then OK, and restart your computer.
  

Let us know how it goes.

You are definitely right, it is not a browser specific issue. The reason for us trying to install the Security Certificate to your computer is for your browser to identify the secured website that you are trying access.

Since you are not getting a prompt on your browser to install the security certificate, please follow these steps on how to Manage Trusted Root Certificates in Windows:

• Open Run box by pressing Windows icon + R then type
  mmc and hit enter.
• Click File and select Add/Remove Snap-in.
• Under Snap-in, select Certificates then click
  Add.
• Click OK and in the next dialog box, select Computer account, then
  Next.
• Select Local computer and then click on Finish.
• Double click on Console Root and select Certificates, right click on
  Trusted Root Certification Authorities. Under All tasks, choose
  Import.
• Certificate Import Wizard should open, then follow the instructions to complete the process.

Let us now configure and manage trusted root certificate for local computer.

• Open Run box again and type mmc.
• Click File and select Add/Remove Snap-in.
• Under Available snap-ins, click Goup Policy Object Editor, then click
  Add.

• Going back in the MMC console tree, got to Local Computer Policy> Computer Configuration> Windows Settings > Security Settings. Next is
  Public Key Policies. Double-click Certificate Path Validation Settings, and then select the
  Stores tab.
• Select the Define these policy settings, Allow trusted root CAs to be used to validate certificates
