Hi everyone ! I am having trouble in accessing the internet through Firefox. Other browsers on my computer works, only firefox is having this error. I am not sure what may have caused this. I access the internet through WiFi, I don't use VPN and didn't change the DNS settings. I have also updated to the latest version of firefox, but this error still persists. In the screenshot, I was trying to access youtube.com, but this error persists on any other websites that I try to access including mozilla.org. Please let me know how to fix this error. Thank you !

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.
