On my Facebook page there is a black Adobe Flash Player "F" showing up where ever you would see a photo album or a place to upload photos. It has been there for several weeks. When I click to upload photos, it asks me to stay on that page or leave the page. If I click to leave the page, it takes me to another page & gives me 2 options: 1) to install Flash Player (which supposedly is already installed via Google Chrome & updated) or 2) upload photos 1 by one via manual upload. This has been happening for at least the past week. I have tried to uninstall Google Chrome and Adobe Flash Player and reinstall both with no success. Can anyone help me with this problem? I really need this fixed because I am unable to upload any pictures to Facebook at this time because of this black "F" on my page. THANKS!!!
