If I go to Amazon.com and look at my orders or look at any item that has images you can expand both FireFox AND Chrome will freeze. IE is still OK. Not sure when this happened but I do not know if it is related to blocking popups or not. Could it be related to a Win 10 or NS update? The Win10 forums say they do not have this issue, so I wonder if there is a setting in NS I could look at?
