About two weeks ago I was having problems with Netflix going between a black screen and the video, but not on all shows. I deactivated Prime-time Content Decryption Module and everything worked just fine, for about a week. Because that plugin was turn off I was now getting a message from Netflix that I needed it turned back on. And again video would start that black screen and then video, over and over. Refreshed Firefox also uninstalled and reinstalled Silverlight. Chrome and Edge were not working two weeks ago but Firefox was. Now Firefox isn't working but Chrome and Edge is, they've switched.
