Firefox v.102.0.1 no longer loads video
Is there a Setting in Firefox that prevents video from playing? Everything is functional except the displaying of programming i.e. only a blank window appears. However, Chrome has full functionality of DirecTV Stream including video playing.
I have been using Firefox for DirecTV Stream on my laptop (Win10) since May without a problem. Then I updated Firefox two days ago to v. 102.0.1 and then lost the ability to open New Tabs with URLs, bookmarks, etc. So I followed the Troubleshooting advice and Refreshed Firefox, which restored all functions but deleted Extensions, Themes (including Norton Password Manager!). I have since restored Extensions including password manager, but cannot use DirecTV Stream any longer in Firefox. Help!
