Why do I get the error "Your browser does not recognise any of video formats available" ONLY ON YouTube and embeded videos + very few ads ?
If i enter a video through google search,i also need to do this forward and back move to see it.
It was fine until 1-2 weeks ago,then,over day,it suddenly stopped working.
I have windows XP and won't change it for anything,i also have Firefox 42 and won't change it,except maybe only some few numbers up,as i don't like the latest design of it.
Why do i get this error and how do i fix it ?
