Mozilla Firefox withdrew support for older encryption protocols this year because they thought it was a good idea. They then re-instated them due to the end use backlash, and have now once again removed them. Regardless of the thinking behind this, we as a provider of services to many systems have to support the full range of protocols, especially for our legacy customers. 

We have customers using Windows XP and Internet explorer 8, we have UNIX5 customers using netscape navigator and we have Sun users running sun's own solaris browser, none of which can support anything above TLS1. 

For this reason, GENX will remain supporting protocols back to SSL3 for the foreseeable future and legacy customers will remain on this platform until they've migrated/upgraded at which point we'll transition them to the Dakota & Andromeda platforms. 

For customers on GENX/GENZone that now receive a Firefox warning SSL_ERROR_UNSUPPORTED_VERSION, there is a workaround to fix this in the short term. 

• Open Firefox
• In the address bar type about:config
• Click through any warning
• In the search bar at the top of the page, type tls.version
• From the list presented select security.tls.version.enable-depreciated
• Double click this line until the value is true (originally it will be false)

Now close Firefox, and re-open. Everything will work as before and the error will be gone when accessing GENX as well as other legacy sites that still support older protocols.
