If one has already done all that and, following the most recent FF
update, all that is displayed is a video window with the Flash
logo/Button in the middle.  And regardless of how many times one
clicks on said button no video will show or sound will emit, what

I went into YouTube and switched to HTML5.  Then, and only then, the
original problem videos would play when revisited.

This is not much of an annoyance for me since watching YT is not very
high on my list of things to do.  Curiously, in many cases linking to
a YT video though an outside website allows videos to play when
directly accessing the same video from the YT site displays the

Unfortunately we work in a regulatory regime that requires constant
updating and the government contractors providing the updates tend to
use Flash as their preferred platform, albeit not on YouTube so the

that Canadian Government is not going to pay to have this material
redone in OGG/OGV/OGX.
