Why am I getting a banner saying No Video wuth Supported Format and MIME found?
I am getting this banner in a free site since two weeks ago. Before that and for many years I was able to watch, save to watch later or download a video using Firefox downloader. Now I can not even log out or log in. I must to have done something wrong as both my Macbook Air and iMack desktop get the same banner. Please kindly help. Thanks in advance
MacBook Air 13″, macOS 13.5
