Hi, since my New website I have not been so happy with Firefox. It won't play the embeded video's from vimeo and I have a lot of them. When a Firefox user wants to play my work they only get sound. Please fix this problem! Remco P.s. My software is up to date

Are there any error messages in the Web Console (Firefox/Tools > Web Developer)?

What code do you use to embed the videos? Is that in an iframe because the embed tag may not work?

That is an MP4 file that plays without any problem for me. 

Type: Video
Codec: H264 - MPEG-4 AVC (part 10) (avc1)
Resolution: 1920x1080

Type: Audio
Codec: MPEG AAC Audio (mp4a)

If you do not see the video then you may be missing support the H.264

Hi, The problem is that not all computers have the problem (-; We have 3 up to date macs and 2 of them play the video 1 not. Since I released my new site 5 days ago I have had about 10 complaints that firefox won't play the video and they only get sound.

Firefox doesn't include H.264 because it's not free and needs the company to pay for licensing, so your OS must provide H.264.

I'm not sure about Mac, but this is how it's fixed on Linux:

Install totem-mozilla 

  sudo apt-get install totem-mozilla

(Windows provides H.264 by default)

I cant ask everyboby to install this. I think Firefox should enable every sort of embed video!

If there is no support for HTML5 media then Vimeo offers a Flash player and the Shockwave Flash plugin is used and should be enabled (Lego block icon on location bar).

  • http://f.vimeocdn.com/p/flash/flideo/1.0.3b10/flideo.swf

That should be the default on Mac as there is currently no support for H.264 media on Mac. On Windows (media.windows-media-foundation.enabled and media.directshow.enabled) and Linux (media.gstreamer.enabled) there is usually support for H.264 media available and you get the built-in HTML5 media player. If that media player can't handle the media file (i.e. the necessary codec isn't installed) then sound and/or video might be missing.

I have the exact opposite problem. When I try to play VIMEO videos, all I get is the picture and no sound.

They play fine in Internet Explorer. I'm using Windows 8.1. I think there was some kind of Windows automatic update that happened when I shut down yesterday. Don't know if it's related but I never had this problem before.
