Hello
I have more and more troubles using firefox in professional environment with CentOS6. The latest version is 45.7.0 But I can't use it anymore to access some old server hardware (IDRAC7 of DELL C6100) because of "/SSL_ERROR_WEAK_SERVER_CERT_KEY/". I had to install an old Firefox32 version to administrate these servers.
Can you try: (in Firefox's about:config): possible workaround for SSL_ERROR_WEAK_SERVER_CERT_KEY security.ssl3.dhe_rsa_aes_128_sha security.ssl3.dhe_rsa_aes_256_sha
Today I upgrade the firmware of 2 DELL switch and now Firefox cannot connect to them anymore saying: /An error occurred during a connection to xxx.xxx.xxx.xxx. The server rejected the handshake because the client downgraded to a lower TLS version than the server supports// //SSL_ERROR_INAPPROPRIATE_FALLBACK_ALERT
possible workaround for SSL_ERROR_INAPPROPRIATE_FALLBACK_ALERT security.tls.version.max 3 -> 1
You might want to revert for safer browsing, after.
/Is there a CentOS6 recommended web browser allowing continuous connections to olds and new base level (and local) system administration services ?
maybe different profiles with differents security setup?
Cheers
