Try visiting about:config and temporarily toggle
security.ssl3.dhe_rsa_aes_128_sha and security.ssl3.dhe_rsa_aes_256_sha
to false-- that got me to a portal that was causing the same issue. Then
after you get online you can set them back to true.

Title:
  firefox 40 shows a non-overrideable security error when talking to a
  captive portal

Status in firefox package in Ubuntu:
  New

Bug description:
  When trying to connect to the airport wifi at the Portland Airport
  (https://flypdxconnect.portofportland.com:8443/guestportal/gateway?sessionId=eb0a3d0a003315a2c104ce55&portal=LOC1&action=cwa),
  firefox presents me with a non-overrideable security error:

  Secure Connection Failed

  An error occurred during a connection to
  flypdxconnect.portofportland.com:8443. SSL received a weak ephemeral
  Diffie-Hellman key in Server Key Exchange handshake message. (Error
  code: ssl_error_weak_server_ephemeral_dh_key)

      The page you are trying to view cannot be shown because the authenticity of the received data could not be verified.
      Please contact the website owners to inform them of this problem.

  When the user is behind a captive portal and talking to that portal is
  the only way to get Internet access, it is not acceptable to enforce
  an SSL security policy where the user has no way of overriding it, no
  way of fixing the server, and no reason to care about the security of
  the connection to this server.

  As a workaround for this issue, I ran chrome.
