Firefox (on one of my Windows computers) has begun hanging up during loading of video articles (such as news services, CNN, CBC, etc.). If I refresh page the video article will occasionally load. Often not. Have uninstalled Firefox and reinstalled. Did not help. Have another Windows laptop and there is no problem loading video content on that device. In addition occasionally Firefox will hang up just loading an assortment of websites, though this does not occur with the regularity of the non-load of individual video news articles. Thank you for any advice or suggestions.
