Actual results:

Whoops, something went wrong ...

We're having trouble playing Netflix on your browser.  Please make sure that you are on an official version of Firefox.
Error Code: F7355

Netflix streams ok in Google Chrome.

FF, both versions, plays Youtube with no problems.

Spoofing UA as FF ESR/linux does not change result.

pshau, does Firefox 64 work as expected? 

Alex, did you reproduce this? If so could you let me know the distro?

(pshau appears to have disabled their account, so I'm unsure if we'll hear back form them)

I confirmed after the discussion we had in IRC. I tried it but it didn't reproduce. I tried my system nightly and the dev edition. pshau tried on Nightly as well and he did have the same issue. I guess it's a general configuration that he is missing.

Nothing in the Rejected System Calls section of the about:support.  The other thing to try is running firefox from a terminal and seeing if anything starting with "Sandbox:" is printed when it fails.  Also, there might be crashes reported in the kernel log (dmesg).

Bug 1496988 might related: also Fedora, and the plugin process failed to pre-open the plugin file before starting sandboxing.

Bug 1506368 might also be related: that was on Ubuntu and didn't reproduce on a clean install, but there was an AppArmor policy blocking the plugin load.

Hi,
If this could help...I've encountered a related issue on Windows 7 testing with Nightly version build 67.0a1 and my error was: "Whoops, something went wrong... the video couldn't start" - bellow of the screen was triggered an Error Code: F7355. At the top of the screen appears a bar with a button "Learn how" - is needed to install "Windows Media Feature Pack". The installing process it takes more than 15 minutes. Here is a link to do that: https://support.mozilla.org/en-US/kb/fix-video-audio-problems-firefox-windows?as=u&utm_source=inproduct After that, the video/s will be played properly.
