Add Exception for Hardware Appliance Not Working on 37.0.1

Posted

Before I upgraded to v37.0.1 in the last week I was using v31. I used v31 to connect to a EMC VNX5400. The connection to the appliance is a secure connection and when I browsed to the appliance the very first time (many moons ago) I had to add an exception. No biggy. Upgrading over the years it has never been necessary to add an exception again, because I just upgrade FF.

However, after the upgrade to v37.0.1, I browsed to my appliance like always but was confronted with the "This Connection is Untrusted" dialog. Which wouldn't be a problem except, when I click on the "Add Exception" nothing happens.

I have deleted the existing certificate, which was still there by the way, from the certificate store in Options->Advanced->Security.

Manually trying to add the exception also doesn't work. I attach a screenshot of this.

Any ideas why FF is behaving in this way?

If you have the ip of the server you may be able to detect what tls/ssl version its using:

There was an update to the fallback TLS tolerance in Firefox. There are two work arounds, adding the dns name to the list of allowed domains in the about:config page or to change the general fallback limit to 1. The former is a bit more secure since you mentioned that the connection is a secure one.

In order to change your Firefox Configuration please do the following steps :

  1. In the Location bar, type about:config and press Enter. The about:config "This might void your warranty!" warning page may appear.
  2. Click I'll be careful, I promise! to continue to the about:config page.
  3. Later: security.tls.version.fallback-limit = 1 or Former: (borrowed from cor-el)-> security.tls.insecure_fallback_hosts

You can double-click the line to modify the pref and add the full domain to this pref. If there are already websites (domains) in this list then add a comma and the new domain (no spaces). You should only see domains separated by a comma in the value column.
