"Secure Connection Failed" https//www.Merriam-Webster.com Windows 8.1
Latest update issue? Windows 8.1 here. Not able to access www.merriam-webster.com site from Firefox, Chrome, nor Internet Explorer with Ethernet connection nor WIFI. I can access the site from my Windows 10 laptop running Firefox. Also have had issues with other sites, but was able to resolve by clicking the appropriate button. Sorry I can't describe this better in a more technical manner.

There is security software like Avast, Kaspersky, BitDefender and ESET that intercept secure connection certificates and send their own.

I see this in "Tools -> Page Info -> Security" (screenshot).
You can check the connection settings.
- Settings -> General -> Network: Connection -> Settings
If you do not need to use a proxy to connect to internet then try to select "No Proxy" if "Use the system proxy settings" or one of the others do not work properly.
See "Firefox connection settings":

Boot the computer in Windows Safe Mode with network support to see if that has effect.
