OpenH264 Video Codec provided by Cisco Systems, Inc.

I just got a Pi 4b with 8gb. So I picked up SanDisk MicroSD 64 GB with 170Write. Loaded the Ubuntu Desktop 20.10. It boots in 30 seconds. Wow... Printer setup was super easy... Had to add Clementine to Play M4A music from itune files. Ok... Loaded just fine. Plays Great. The Ubuntu 20.10 comes with Firefox 81.0 browser. My favorite Browser. Went out to my Favorite Anime site to play some video. Animefreak.tv Error loading player: No playable Sources Found Well the Video Codec plugin not there. Checked the Add-ons Enabled OpenH264 Video Codec provided by Cisco Systems, Inc. This plugin is automatically installed by Mozilla to comply with the WebRTC specification and to enable WebRTC calls with devices that require the H.264 video codec. Visit https://www.openh264.org/ to view the codec source code and learn more about the implementation. ''' ! OpenH264 Video Codec provided by Cisco Systems, Inc. will be installed shortly.''' So I installed the new version of Firefox 84.0.2 (64-bit). ok. I am using it now. No Video play back in Firefox on Ubuntu 20.10. Same Problem. I turned on the Allow Automatic updates in firefox openH64 Video Codec. Maybe it will update and install. Well I am not holding my breath. Its to bad, because the Pi 4b is just as fast as my Laptop HP envy running win10. If you can find a fix. I would be grateful.
