Hello mariee9380478, all mayor browser vendors - Apple, Google, Microsoft, Mozilla - decided to prevent certain plug-ins from being activated by default. Additionally, Adobe announced plans to no longer support Flash by the end of 2020 and browser vendors will follow by gradually removing Flash support from their desktop browsers. For now, you have to include every website that uses Flash as an Exception (see this Guide for Opera). In the long run, XFINITY and other websites that still use Flash elements might consider switching over to HTML5. Kind Regards, Maurice
