Firefox and flash plugin

[Terry Polzin]

Firefox is complaining about flash not being up to date.  I believe i have
the latest of both.

dnf list installed | grep -e firefox -e flash-plugin
firefox.x86_64                       52.0-6.fc25
@updates
flash-plugin.x86_64                  25.0.0.127-release
