So everytime I load up a webpage on this site(and a few others) it says "an additional plug in is required ot displays ome elements on this page." and gives a button to "install plug-in" but pressing it does nothing. And it loads up EVERY TIME I GO TO A PAGE ON A SITE. So it's annoying. Any idea what could be causing it?
You either don't have Java (http://java.com/en/download/windows_manual.jsp?locale=en) installed or Adobe Flash Player (http://www.adobe.com/products/flashplayer.html). If both of those are installed and you're still receiving the error, try switching between different browsers. If the error still consists, that means there is another plugin that needs to be installed. Since "install plug-in" doesn't seem to work, again try different browsers and maybe it'll redirect you to the proper site.
uninstall the skype click to call plugin. It bothered me for a week or two and then I went and did some research.
