I can't reproduce this. I set the screensaver to the minimum of 1 minute, then tried a YouTube video and this random search result:

New profile didn't help, screensaver still starting, while video is playing.

Anthony, do you know whether we try to suppress the screen saver while videos are playing currently?

We should suppress the screensaver when playing full screen video. There are too many screen savers on Linux for it work on all of them. However this issue may have been fixed in another bug relating to XP screensavers.

Reporter, please test the latest Nightly in a brand new profile and report back whether the screen saver still kicks in.

I think this was fixed by bug 1193610.

julia breink, it would be much appreciated if you could test in an up-to-date version of Firefox 43 or later to see if the problem has been fixed. Thanks!
