A additional difference is that both Microsoft Edge and Google Chrome rely on the Windows certificate storage for SSL certificates and etc. while Firefox again has its own inbuild certificate storage. Not sure what to do about that but what if your Windows certificate storage is broken or something like that.

That is your issue. See the post by @fChk --> https://post4vps.com/Thread-Chrome-and-E...9#pid35259

The Windows certificate storage is out of date. Hence why some sites appear as insecure and others not. Firefox works fine because it has its own certificate storage that gets updated with Firefox updates.
