Comment 29 for bug 1309744

With a fully patched Lubuntu Trusty, streaming Flash video through Firefox results in the screen blanking and locking after 10 minutes.

I have the recommended/most-recent version of xdg-utils.

Does this mean that media players in general use xdg-screensaver to inhibit the screensaver while playing video, but that Firefox does not?

If so, is there a workaround?
