[CentOS] Firefox 39

Hello,

Trying to access webmin but I get the error: ssl_error_weak_server_cert_key.

I tried uninstalling Firefox and re-installing 38.x but still get the error.

I tried installing Chrome but the dependencies are an endless loop.

I found instructions on how to fix the error but I can't access webmin to do
it.

Any help would be greatly appreciated.
