Did Not Connect: Potential Security Issue
Having updated Firefox today on my oldest Windows desktop computer, I encountered a "did not connect: potential security issue" error message when I tried to open Firefox, which is operating normally on my other desktop computers.
Thank you in advance for your assistance.

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