Description of problem:
I'm having a problem with the wikipedia.de website since some firefox versions: If I try to open it,
I get some warning issue:
-----------------------------------------------------------------------------
Your connection is not secure
The website tried to negotiate an inadequate level of security.
wiki2.wikimedia.de uses security technology that is outdated and
vulnerable to attack. An attacker could easily reveal information which
you thought to be safe. The website administrator will need to fix the
server first before you can visit the site.
Error code: NS_ERROR_NET_INADEQUATE_SECURITY
--------------------------------------------------------------------------------
Version-Release number of selected component (if applicable):
firefox-57.0-0.8.fc26.x86_64
How reproducible:
Always
Steps to Reproduce:
1.Start firefox
2.Try to open https://www.wikipedia.de
3.
Actual results:
See description
Expected results:
Additional info:
1. Until some FF versions before (don't remember, which one), I had no such warning issues
2. I don't know, whether this is a FF problem, or a problem of www.wikipedia.de.
I could solve the problem by purging the FF cache.

This is actually a bug, and clearing the firefox doesn't help.
The problem is as described here:
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=833719
You need to update ‘nss’ to the version in Fedora 27.
firefox could be fixed here by having it require a minimum
version of nss.
This problem was still present in Fedora 28 (which is past end of life).
I had to manually update nss and restart firefox to fix the problem
One would expect this to be fixed;
i.e., the install of firefox would require a new enough version of nss.
