When i'm on youtube I like to open loads of tabs before going through each one later. With click to play for flash this wasn't a problem, but html5 will autoplay and get very annoying. Is there a way around this? Do you think Youtube would be for or against that (i.e. do they really want me opening more than one tab?)
