secure websites won't open
Last night firefox stopped letting me open any https websites. Chrome doesn't have any problems, just firefox. I have version 63.0.3. I have tried everything that I find on the internet to try. I have windows 10 and am using the windows defender firewall, there are no family settings that are set up. Can anyone help? Below is a screen shot of what I am getting when I try to go to google.com

Apparently the picture didn't go through
There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connection certificates and send their own.
- uses an invalid security certificate SSL_ERROR_BAD_CERT_DOMAIN
- configured their website improperly

Thanks Fred. As I stated before I have no other anti virus software installed on the computer. I have tried everything in all those articles. I have been at this for a few hours now and still not working.
Now I have tried uninstalling and reinstalling firefox. It's pretty bad when I can't even get to the mozilla page!

Does that ring a bell?
You can set this pref to true on the about:config page in case other software adds its root certificate to the Windows certificate store.

Fred-Windows defender. Turned it off yesterday and no change
Cor-el- I think I tried that yesterday and it worked but I didn’t think I could leave that as true. Is that something I can do?

Cor-el, thanks for the reply. I downloaded all those and ran them. Re-started my computer and still the same error message.
