Secure Shopping displays non-defaul browser IE instead of Firefox

A. THE BUG/ISSUE (Varies from issue to issue)
Can you reproduce the problem & if so how reliably?: always

If you can, exact steps to reproduce. If not, exactly what you did & what happened:
1:new Windows 10 Pro with Firefox browser set as default system browser under Settings → Default Apps → “Web browser” shows Firefox.
2:install latest Comodo Secure Shopping (standalone) product - no other comodo product is installed on the system
3:enter the secure shopping environment

One or two sentences explaining what actually happened:
It shows Internet Explorer, NOT Firefox.

Further, under “Settings” of Secure Shopping, it shows Internet Explorer, System default browser, Secure Shopping Default browser. Firefox does NOT appear among options at all. None of the options allow me to make it so that Firefox is used inside the secure shopping environment!

Another, and probably related bug: after manually double-clicking C:\Program Files(x86)\Mozilla Firefox\firefox.exe, it requires firefox in the main environment to close! Apparently, it cannot run both, firefox copy within secure environment and firefox copy outside of secure environment. That’s NOT how it works on my other computer, where I have the whole Comodo suit installed. I am happily running firefox in both, in parallel and firefox IS the browser that appears within the secure enviromment, so I don’t have to look for it in the Windows Explorer.

One or two sentences explaining what you expected to happen:

Firefox, the default system browser, should be appearing inside the Secure Shopping environment. Not the IE.

Firefox should be able to start another window within the secure environment, even if firefox is already running outside the environment.

Any software except CIS/OS involved? If so - name, & exact version:

Firefox 60.2.2esr (latest ESR version) is installed in standard location (C:\Program Files(x86)\Mozilla Firefox\firefox.exe)
