Thank you for the report. If you open the page about:studies in Firefox, is there under Active studies one with the name Software H264 decode pref flip followed by control and Active?

media.peerconnection.enabled is the master pref to control WebRTC features. It probably isn't causing issues on sites like Netflix.

Try opening about:config, and setting media.gmp.decoder.enabled=false, then restart. That should fix the issue. Note though you'll want to clear that when 159 ships in two weeks.

The Bugbug bot thinks this bug should belong to the 'Core::Audio/Video: Playback' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.
