I have not used signed/encrypted email in a long time, so am not willing to test this, but can confirm that this update makes Enigmail available again in the latest version of Thunderbird.
Also, as an aside, mozilla-noscript hasn't been updated in a long time. The current Fedora build is 10.2.1, upstream is 11.0.3. It looks like mozilla-ublock-origin is monitored by https://fedoraproject.org/wiki/Upstream_release_monitoring but mozilla-noscript is not?

https://bugzilla.redhat.com/show_bug.cgi?id=1692129 (filed against ruby, the source package for rubygem-irb)
I filed the second bug. I'd mark it as a dupe, but am not sure about the package.
