I am trying to get Netflix to play on my new Macbook Air (M1). Not working. A little sleuthing led me to check about:addons, where I see this message "OpenH264 Video Codec provided by Cisco Systems, Inc. will be installed shortly." However, the installation is not happening. Help!

Hi,

we're not using OpenH264 Video Codec for Netflix. Perhaps you have to install Rosetta. See Netflix, Hulu, Disney+ or Prime error after installing Firefox version 84 on Mac.

Note that Netflix uses Widevine to play DRM protected videos.

Try to toggle DRM off/on to see if that makes Firefox (re)load DRM components.
