i am confused though. there is no issue on firefox on windows. firefox does not use windows' list. chrome use windows' list. so even if microsoft had approved of this certification authority, firefox on windows should still be showing the same error that chrome is showing on android.
For example... rtionline.gov.in does not work in Firefox on Windows because the certificate issued is not recognized globally. Microsoft appears to have approved it on its own probably because Indian government asked them to. So IE/EDGE/Chrome does not show any errors.
