JW Player 6.8.4616 (Premium edition) + Mac + Firefox 29.0.1 + no Flash Player installed = buggy

Hi there,

I'm experiencing the following issue:

On Mac OSX, Firefox 29.0.1, no Flash Player installed, I open a page in my project containing the following code:

<div id="myElement">Loading the player...</div>
<script type="text/javascript">
file: '',
image: '',
width: '100%',
aspectratio: '4:3'

- The console says: "No suitable players found and fallback enabled"
- There is a player with a thumbnail but the dimensions are wrong (appears to be 16:9).
- When I click the play button I get redirected directly to the video file, in the same window.
- The jwplayer logo is visible, despite the presence of a self hosted license key in the page head:
<script type="text/javascript">jwplayer.key="mySecretKeyForSelfHostedPlayer";</script>
<script type="text/javascript" src="/jwplayer/jwplayer.js"></script>

To reproduce the issue somewhat on your own site:
On Mac OSX open FireFox 29.0.1
Be sure Flash Player is NOT installed
- The player seems to load, the video thumbnail appears
- The logo is visible
- When you click play you get redirected to the video file directly, in the same window

The player works as expected in all other browsers I've tested in.

I've tried all the suggestions I could find in the FAQ and question section but can't seem to work around the issue. I hope you can help me out.

Thanks for your time!

No surprise, there. Firefox on OSX does not have the ability to use the native HTML5 <video> tag, so with JW Player, it falls back to Flash. With no Flash, it has no way to play the MP4.

Since Firefox does not support HTML5 video tags and Flash is not present, you would need a fallback: ‘false’ to provide for a direct download:

<div id="myElement">Loading the player…</div> <script type="text/javascript">
file: ‘tears.mp4’,
image: ‘tears.jpg’,
width: ‘100%’,
aspectratio: ‘4:3’,
fallback: ‘false’

Hope this helps,

Thank you Todd.

adding fallback:'false' to the setup still yields "No suitable players found and fallback enabled" in the console. Behaviour on the page remains exactly the same as when omitting it from setup.

Thank you MisterNeutron, that is a very clear explanation.

That is strange. I’ve tested this in Firefox 29.0.1 on my Mac with Flash disabled and the player is pointing the browser directly to my .mp4 video. Please e-mail a link to your page to me at
