So I noticed this problem while using Facebook, none of the videos will play. When I attempt to play the video, the "Couldn't Load Plugin" comes on with the grey screen and puzzle piece. Oddly, however, videos work fine in YouTube. I have installed the latest Adobe Flash Player and checked about:plugins to insure it was enabled. I have deleted cache, history, and browsing data. I just don't know what do anymore and this is insanely frustrating! How do I fix this??
I am running on Windows 8.1, using Chrome browser (also updated).
