I generally watch lot of lengthy videos on YouTube. I always experience a problem because the screensaver is activated every 5 minutes.
I would like to know how to disable the screensaver while watching flash videos. I know, that I can change the screensaver timer or completely disable the screensaver. But I don't want to do that. I just want to disable it while I am watching full screen videos on my browser.
Update: I am using google chrome.
