Have been trying to fix this problem - FF works beautifully if Kaspersky Internet Security is OFF but cannot access any websites when it is ON - just this PR_CONNECT_RESET_ERROR page.

Kaspersky support has been assisting but no solutions as yet. Any help from Mozilla is appreciated. This has been going on for 4 days now.

Using FF version 94.0.2 (64-bit) on Windows 10.

I've tried debugging the extension, errors in attachment

Web search; https://www.bing.com/search?q=PR_CONNECT_RESET_ERROR This simply means, that the peer or some middlebox in between (firewall) is terminating the connection.


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