Searching Google led me to go to about:config and look for media.windows-media-foundation.enabled and switch it to true. However, this option doesn't even show up in the list. Please advise.

I assume you get the overlay. What error do you see, or is it blank?

If you follow the View on Vine link, same error there: https://vine.co/v/iwImIZXL3It

I notice it uses a mediasource: link when I try to view it:

<video poster="..." src="mediasource:https://vine.co/63db4d9f-62dc-4cd2-a165-07acef41cd6e" preload="auto" height="540" width="540">

But if I disable that (set media.mediasource.mp4.enabled=false) then it serves me this and still plays:

<video poster="..." src="blob:https://vine.co/d7622a28-413f-486b-8dc5-b83006980026" preload="auto" height="540" width="540">

So... I am not able to guess what's going on without some more information. You also might check the web console:

  • Open the console in the lower part of the tab using either
    • Ctrl+Shift+k
    • menu > Developer > Web Console
  • Then reload the page in the top part of the tab and watch for error messages related to the video

thanks, no apparent issues there... would you happen to know if you are running a windows n version? in this case Fix video and audio problems on Firefox for Windows N editions should help.

I downloaded that update but it said that it wasn't applicable to my computer. So I guess I'm not running an n version? *sigh*

Searching Google led me to go to about:config and look for media.windows-media-foundation.enabled and switch it to true. However, this option doesn't even show up in the list.

By the way, this preference is now called media.wmf.enabled and it is set to true by default. But you still might want to double-check it, especially if you have the same problem playing the MP4 video on the following test page (scroll down to the first player):

http://www.quirksmode.org/html5/tests/video.html

media.wmf.enabled is set to True. I was able to play every video on the page that you linked. Vines are the only type of videos that I have never been able to play on Firefox.

Could you link to a vine that doesn't play (to save me from having to search around!)? Thanks.

WOAH! Setting set media.mediasource.mp4.enabled=false made it play! Thank you! I hope this applies to all vines I encounter.

Hmm, maybe something is broken with mediasource on your Firefox. I haven't heard of that before. What does (did?) the YouTube test page show for "Media Source Extensions" and "MSE" (second row):

https://www.youtube.com/html5

If you reload, the page should redetect, so you could test with that preference flipped true and false to see which boxes go red.

more options

Only 'MSE & H.264' shows an error if I set the mediasource setting to false. But this lets Vines play.

If I set the setting to true, the YouTube page shows no errors, but I can't play Vines.

Maybe it's a bug in the 64-bit build of Firefox. Did you have this problem before you started using the 64-bit build?

I was primarily using Chrome for a couple years until I went back to Firefox a few months ago. I'm not sure about if there was an issue beforehand.

I'm having the EXACT same issue like user "Tyranitator". So exact even his fix of media.mediasource.mp4.enabled=false worked for me too. I also got the same results as him where https://www.youtube.com/html5 - everything was golden before, yet vines wouldn't play. Then once setting that option to false, vines started working but it said "H.264 and MSE & H.264" wouldn't work under the YouTube HTML5 page. So I think the core issue has to do with the 64-bit version of Firefox somehow. I'm using 64-bit version 45.0.1 Firefox and his problem and fix is the exact same results for me.

Before finding this post right here, this is what I tried myself to fix it:

I try to watch a Vine, doesnt work. I start Firefox in Safe Mode, the Vine works. I then think "Oh it must be my exentions and plugins/hardware acceleration", so I start regular Firefox with everything disabled, Vine still doesn't work. I even "Refreshed Firefox" and nothing changed and my graphic drivers are all up to date already.
