I am having strange problems with youtube lately when opening multiple tabs of Youtube on Safari. What happens is once you open a few videos simultaneously, most pages will load then a few will give up and download the youtube video as an MP4 video. Its very annoying because the page will just be blank white, or sometimes even the url field is blank. Been using mac for around 3 and a half years now. This only started happening about 3 weeks ago. Anyone else having this issue? Thanks.
