Error code: ssl_error_weak_server_ephemeral_dh_key

After the recent Firefox updates regarding the SSL and TLS, you might face one of these SSL errors and happily there is a simple fix for this error which is…Open the firefox configuration page, write in firefox navigation/address bar “about:config”. If it’s your first time to open it just ignore the alert and continue..

In the search bar, write “security.ssl3.dhe_rsa_aes_128_sha” then double click on it to change it’s value from “True” to “False”.

Again search for “security.ssl3.dhe_rsa_aes_256_sha” then do the same by double clicking on it to change it’s value to “False”.


That’s it, now  you can open these websites without any problems!
