I have used firefox for ages. No problems. All updates come along automatically. Fine.
Over the last few weeks Firefox has started having massive trouble with video - youtube, vimeo, sports streaming, tv streaming - and i've started using IE for video. Why?!!?!?! WTF is going on?!?!?! What downloads / plugins have somehow not updated themselves??!?!?
I find installing VLC - (videolan.org) usually sorts any of my pc related video watching issues.
