+- update to NSS 3.26.2
+  * required for Firefox 50.0
+  Changes in 3.26
+  New Functionality:
+  * the selfserv test utility has been enhanced to support ALPN
+    (HTTP/1.1) and 0-RTT
+  * added support for the System-wide crypto policy available on
+    Fedora Linux see http://fedoraproject.org/wiki/Changes/CryptoPolicy
+  * introduced build flag NSS_DISABLE_LIBPKIX that allows compilation
+    of NSS without the libpkix library
+  Notable Changes:
+  * The following CA certificate was Added
+    CN = ISRG Root X1
+  * NPN is disabled and ALPN is enabled by default
+  * the NSS test suite now completes with the experimental TLS 1.3
+    code enabled
+  * several test improvements and additions, including a NIST known answer test
+  Changes in 3.26.2
+  * MD5 signature algorithms sent by the server in CertificateRequest
+    messages are now properly ignored. Previously, with rare server
+    configurations, an MD5 signature algorithm might have been selected
+    for client authentication and caused the client to abort the
+    connection soon after.
