I thought that was the case too.  However, disabling NoScript for
YouTube does not change the observed behaviour.  It is decidedly odd
in that the Flash video will not play until one sets the enable html5
option in YouTube.

One of the artifacts of switching the html5 on in YT is that upon
returning to the video page the video canvas shows an error message,
with the 'Try again later' tag.  But simply clicking on the video
frame a second time starts the video.

I am not sure what is going on.  I have discovered that the same
approach (switching on html5 in YouTube) has solved this issue for a
least one of the impacted users.  I will try it on others as the
occasion permits.

It seems to me likely to be a FF issue at its core.

I solved that for Firefox 35.x.


I added some symlinks to $HOME/.mozilla/plugins

Here is the list of symlinks:

[drlove at kanc ~]$ cd $HOME/.mozilla/plugins
[drlove at kanc plugins]$ readlink -f *
/usr/lib64/flash-plugin/libflashplayer.so
/usr/lib64/mozilla/plugins/libgnome-shell-browser-plugin.so
/usr/lib64/IcedTeaPlugin.so
/usr/lib64/mozilla/plugins/librhythmbox-itms-detection-plugin.so
/usr/lib64/mozilla/plugins/libtotem-cone-plugin.so
/usr/lib64/mozilla/plugins/libtotem-gmp-plugin.so
/usr/lib64/mozilla/plugins/libtotem-mully-plugin.so
/usr/lib64/mozilla/plugins/libtotem-narrowspace-plugin.so

I have not made java work though, but I have 31.x for that if necessary
