Great when firefox stop updating Puntuado con 5 de 5 estrellas

I tried the beta fix after updating to FF19 and it has sorted many of the problems out. however, I now have the problem of videos not completing their downloads and stopping at a random point (say, at 70mb out of 200mb video file). It has also stopped warning me about cancelling the download if I try to close Firefox down, despite me checking all the settings to warn me.
