"Did Not Connect: Potential Security Issue" on every sites
Since yesterday I am getting this "Did Not Connect: Potential Security Issue" error on every sites that I have tried to visit. Even on well known secured sites like https://drive.google.com is inaccessible while my Chrome and Edge is working fine. Any solution?

Hi FredMcD, Thanks for your response. Unfortunately none of these solution is working out for me. I don not use any third party antivirus or internet security software except for windows defender. However, finally turns out that turning on "Automatic proxy configuration URL" under Setting>Network setting solves the issue. I am not sure whether this will cause any security threat or other malfunction or not.

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

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":
That was very good work. Well Done.
