Hello everyone! My firefox browser don`t load any Addons/Themes/Extensions. I tried to solve it with safe mode, seems that this way didn`t work. Then i reinstalled my Firefox, but problem still stays. Have no idea what to do now. Could someone help me? Image translation: " error name" error occurred while connecting to addons.mozilla.org

In the error message, notice in capital letters: PR_CONNECT_RESET_ERROR

Bing 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.
