There's at least one security vulnerability that is missing from this NSS version: http://www.cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2016-1950
There was a bugfix in NSS https://bugzilla.mozilla.org/show_bug.cgi?id=1245528 to solve this issue but unfortunately it seems that this bugfix is not in 3.20.x according to the developer entries. I didn't check the code yet if the bugfix is really missing! So my question is why seamonkey uses still this outdated NSS version? It should use at least 3.21.1 (that is in latest firefox esr /45.4.0/ and also in latest thunderbird /45.4.0/) As a workaround i can copy the nss libraries from firefox esr to seamonkey until a security release of seamonkey let's say 2.40.1 arrives. I tried this end i can start seamonkey with newer NSS library because they're compatible. _______________________________________________ support-seamonkey mailing list support-seamonkey@lists.mozilla.org https://lists.mozilla.org/listinfo/support-seamonkey
