Leaving this here for future testing reference. Toggling e10s preference: # Open a new Firefox instance without having to deal with "Firefox is already running!" open -n /Applications/Firefox.app/Contents/MacOS/firefox # Verify e10s, "Multiprocess Windows", state about:support # Toggle e10s state (if necessary) about:config browser.tabs.remote.autostart.2 true == enabled false == disabled Restart Firefox
Updated to "High Sierra" (macOS 11) Developer Preview 2. Same result: e10s enabled: No audio from YouTube video e10s disabled: Videos on YouTube now have audio
(In reply to Joe McCabe from comment #6) > Updated to "High Sierra" (macOS 11) Developer Preview 2. Err. By which, I mean, macOS 10.13 Beta 2 (17A291j)
Sooo ... Anything else I can provide? Is anyone else able to reproduce this, or am I special?

Per bug 1376163 comment 3, it looks the same problem here. So close it as a duplicate bug.

Aw man. How does my older bug get marked a duplicate of the newer bug? I've been robbed of first-reporter glory. Regardless - confirmed that "security.sandbox.content.level" to "0" fixes the problem.

(You're still "first reporter"... we often leave the bug open that has the most useful data in it, or the one the dev was working from when developing the patch. You can still bask in the glory, though.)
