<blockquote>Locking duplicate thread.<br> Please continue here: [[/questions/858478]]</blockquote> When you open a tab or several tabs they may have an embedded link to Youtube, which will start to buffer and play automatically. I can find nothing that will stop this. It is very frustrating because I only have 4 gig of data a month, and it often sounds awful, especially if multiple links start playing at once, or playing over what I am listening to. I have added greasemonkey and the scripts Yousable Tube fix, Youtube(no autoplay), Youtube Disable Auto play. And the extention Tubestop 4.. Nothing seems to work is there a solution to this Virus like behaviour?
