Facebook videos "Sorry, we're having trouble with playing this video."
Hi
For two days I've been searching on the web and in here with no luck.
Initially as Facebook is loading ... I can see the video for a brief second, then its turns grey with the message "Sorry, we're having trouble with playing this video."
Appears to only be a problem on Facebook and only in FF (chrome facebook videos work fine)
Using
FF 81.0 (64-Bit) Windows 10 Version 2004
Tried with all addon's disabled. Tried with anti virus disabled
Tried adding "Flash Video Player for Facebook" addon
Videos all work and play in chrome.

Could you check this group of settings:
(1) In a new tab, type or paste about:config in the address bar and press Enter/Return. Click the button accepting the risk.
(2) In the search box in the page, type or paste mediasource and pause while the list is filtered
(3) If the media.mediasource.enabled preference is bolded and has a value of false, double-click it to restore the default value of true
(4) Also check:
- media.mediasource.mp4.enabled (used widely)
- media.mediasource.vp9.enabled (probably only YouTube)
- media.mediasource.webm.enabled (used on YouTube, probably some other sites)
Was anything there turned off and does turning it back on help?

Could you check the following test page, it is my re-post of the old YouTube HTML5 video support test page:
https://www.jeffersonscher.com/sumo/html5-video.html
If there are items that do not say "supported" or "probably", which ones are they?
Hi Jeff
This is what I saw.
Legacy YouTube HTML5 Video Tests
HTMLVideoElement supported MP4/H.264(avc1.42001E, mp4a.40.2) probably WebM VP8 (vp8.0, vorbis) probably
Media Source Extensions Support:
Media Source Extensions not supported MSE & H.264 (video/mp4; codecs="avc1.4d401e") -- MSE & WebM VP9 ((video/webm; codecs="vp9") --

Thanks Jeff
media.mediasource.enabled was False ... and turned to True.
Hi Greg, I don't know how that happened, but I'm glad we figured it out quickly.
I've had this problem for months, if using Firefox standard release. It doesn't occur when using Beta or Nightly. I figured it would eventually propagate through to the final release build, but so far, it hasn't. Video support test yields same results for all three. Config settings(for media.mediasource....) are the same for all three. Just in case, I enabled "experimental" as well.

Hi vic.martin, did you test in Firefox's Safe Mode? In its Safe Mode, Firefox temporarily deactivates extensions, hardware acceleration, any userChrome.css/userContent.css files, and some other advanced features to help you assess whether these are causing the problem.
If Firefox is running: You can restart Firefox in Safe Mode using either:
- "3-bar" menu button > "?" Help button > Restart with Add-ons Disabled
- (menu bar) Help menu > Restart with Add-ons Disabled
and OK the restart. A small dialog should appear. Click "Start in Safe Mode" (not Refresh).
If Firefox is not running: Hold down the Shift key when starting Firefox. (On Mac, hold down the option/alt key instead of the Shift key.) A small dialog should appear. Click "Start in Safe Mode" (not Refresh).
Any improvement?
