Any way to get rid of certificate error using Netgear/Jalbum

When you add the exception to FireFox what you are doing is telling FireFox that it is OK to trust the certificate from your ReadyNAS. I would assume that you trust your ReadNAS so it is OK to add the exception.

In general FireFox is designed to be more secure than IE.

If you want to go as far as to enable ssh and enable ssh to root, which may cause Netgear to note support your device, you can replace your certificate.

First create a config file named readynas_ssl.conf with the following:

[ req ]
default_bits            = 2048
default_md              = sha1
#default_keyfile         = key1
distinguished_name      = req_distinguished_name
prompt                  = no
string_mask             = nombstr
req_extensions          = v3_req

[ req_distinguished_name ]
countryName             = US
stateOrProvinceName     = XX
localityName            = XX
organizationName        = XX
organizationalUnitName  = XX
emailAddress            = XX
commonName              = NAS_FQDN

[ v3_req ]
basicConstraints        = CA:FALSE
keyUsage                = nonRepudiation, digitalSignature, keyEncipherment, dataEncipherment
subjectAltName          = @alt_names

[ alt_names ]
DNS.1 = NAS_Name1
DNS.2 = NAS_Name2

Replace the XX values with the info you want, it really doesn't matter since you are not going to have it signed by a CA. Replace the NAS_FQDN with the fully qualified name for your ReadyNAS. If you want to have multiple names for your ReadyNAS replace the NAS_Name1 and NAS_Name2 with the namesyou want. If you are going to only use one name remove the "subjectAltName" line and all of the lines after it.

In the same directory that you just created the readynas_ssl.conf file run the following commands:

openssl genrsa 2048 > readynas.key
openssl req -new -x509 -nodes -sha1 -days 365 -key readynas.key -config readynas_ssl.conf > readynas.cert
cat readynas.cert readynas.key > readynas.pem 

Now make a backup of the existing certificate file:

cp /etc/frontview/apache/apache.pem /etc/frontview/apache/apache.pem.orig

Now replace the existing certificate:

cp readynas.pem /etc/frontview/apache/apache.pem

Now restart Apache or just reboot the ReadyNAS.
