Firefox & "Partial Content" Failures
Having trouble with Firefox 10 and 11 on both Windows 7 and Mac OS X 10.6
Content is here:
Firebug shows that the server is returning the correct information and mime codes, but is responding with "206 Partial Content" responses. This is apparently because JW Player is requesting the files using the request header "Range bytes=0-"
Not sure that's what's causing this, or why Firefox specifically is the only browser that doesn't like it. The files load and play fine when requested as the URL: just won't play through JW Player.
Upgraded to the latest JW Player, didn't seem to help (though now it doesn't show the "couldn't load content" error messages, it just stops the "waiting" spinner and does nothing).
Thanks for any suggestions,

The JW Player isn’t making the byte range requests; the browsers’ HTML5 video implementations are responsible. The browsers inspect non-sequential areas in the file for a variety of reasons, such as determining whether or not the video is playable in the browser, and to skip ahead to unbuffered regions in the video.Apr 04, 2014 02:57PM EDT
@PabloS - thank you for the response!
It doesn't, however, answer the question. What can I do to make JW Player work with Firefox?
Is anyone else having trouble or is there a misconfiguration on my end that I need to solve?

Your site takes an extremely long time to respond to requests. This may be the culprit. The player checks each video file (in the order specified in the config) to see if it’s playable. In Firefox, it took 17 seconds for the player to receive a response for the MP4 file; when it requested the webm file, the connection timed out.Apr 04, 2014 02:57PM EDT
Upon further inspection, I think the problem is simply with your webm file itself — it can’t be played in Firefox for some reason. Just enter the URL to your webm file into Firefox, and you’ll see an error message.Apr 04, 2014 02:57PM EDT
I have the same issue but it was working fine with firefox 10 then I updated to ff 12 and now JW player wont load at all. I tried chrome, safari and IE and they all play.

I don’t see a player on your example page.Apr 04, 2014 02:57PM EDT
hi there.. I too am facing the same problem.. I am working on a drupal site and have used jw player for the videos.. However, as with other people in this post; in my case as well, the video loads properly but on clicking on it (for playing), it barely plays for a second or so and stops.. let me know the solution of this problem if anyone has resolved it..
Firefox version -> 12.0
Drupal module -> jwplayer, 7.x-1.0-alpha1
OS -> windows7, mac
Also, the video is working fine on other browsers, only mozilla firefox and safari have this issue.Apr 04, 2014 02:58PM EDT
Please post a link to a page where the problem is evident.Apr 04, 2014 02:58PM EDT
HI, I'm currently experiencing a similar problem with the wordpress plugin. The videos are working fine, but when I try to view them with firefox, it doesnt seem loike the player is loading at all, but rather, the image for the video shows and when you click on it, it acts like a link and brings up a download box for the correct video.Apr 04, 2014 02:58PM EDT
Please post a link to a page which demonstrates the issue.Apr 04, 2014 02:58PM EDT
I'm also experiencing issues in Firefox where the player will play the first file, but once it goes to the next one on the list it gets stuck. And then the majority of files just don't want to load randomly. Especially any m4a files it seems. This only seems to happen in Firefox.
Here's a link:

Your web server is serving your m4a files with a mime-type of “text/plain” – it should be “audio/mp4”,Apr 04, 2014 02:58PM EDT
You are a Life Saver! THANKS! :))Apr 04, 2014 02:58PM EDT
Hmmm So having changed the mime-type and played around with it a bit, I wanna report back that the issue still exists. m4a's don't want to load in Firefox. They will load only if I load the actual file first (open the direct link to the file), and then go back to the page with the player. then that single file will load. The rest doesn't. Safari doesn't seem to have these issues.Apr 04, 2014 02:58PM EDT
Your videos work fine for me in Firefox 14 on this link – http://demos.davidbawiec.com/Apr 04, 2014 02:58PM EDT
The videos work, but the audio tracks do not. I'm running FF 14.0.1 on OSX 10.7.4.
The following tracks are m4a files:
-Sailing Up the Amazon
-Driving Into The Night
-Desert Storm Rider
-Leaving The City
Clicking on a track (or just having the playlist go to one of these after another track has completed) leads to the never ending spinning wheel. Clicking elsewhere and going back to the same track sometimes finally loads the song. Now I've noticed that the other tracks which are in mp4, flv and mp3 format do not have such issues. So could it be an m4a thing?
ThanksApr 04, 2014 02:58PM EDT
Your m4a files have – Content-Encoding gzip
Disable it.Apr 04, 2014 02:58PM EDT
I too am having issues with FireFox.
Here is the test page: https://dibels.uoregon.edu/videotest.php
This is working fine on other browsers. When I view the video files, they work fine on all browsers.
As a side note: The same video but with a .ogg level added works on FF but not Safari. https://dibels.uoregon.edu/training/newfeaturesvideo/
I see that the response header is video/mp4 and that it is giving me a 206 partial content.
Any suggestions?Apr 04, 2014 02:58PM EDT
Firebug says – "HTTP “Content-Type” of “text/plain” is not supported. Load of media resource https://dibels.uoregon.edu/videos/new-benchmark-goals.webm failed."
This means your server does not have the right mime types set up.Apr 04, 2014 02:58PM EDT
Thank you for the quick response. I was looking at the .mp4 response headers.
Can you tell me where in Firebug you are seeing that message?Apr 04, 2014 02:58PM EDT
Right in the console. It should be noted that Firefox does not support .mp4/h.264 files in html5 natively.
This is the full output of the console once I press play:
HTTP "Content-Type" of "video/mp4" is not supported. Load of media resource https://dibels.uoregon.edu/videos/new-benchmark-goals.mp4 failed.
HTTP "Content-Type" of "text/plain" is not supported. Load of media resource https://dibels.uoregon.edu/videos/new-benchmark-goals.webm failed.
The video could not be loaded, either because the server or network failed or because the format is not supported.
jwplayer.js (line 1)
All candidate resources failed to load. Media load paused.Apr 04, 2014 02:58PM EDT
Thank you again.
I have added the mime type to apache and it is working!
We are using an older version of Ubuntu so webm was not in the list of default mimetypes.

Not quite the same problem here , but Firefox loads the popup window with jw player streaming the audio, yet fails to show player image, controls, plugins etc.
Works fine across all other browsers, any ideas?

I don’t even hear any audio here at all? – http://funcshn.com/rooms/foyer.htmlApr 04, 2014 02:58PM EDT

Hi guys - I noticed today that the JW Player is not loading my youtube videos in Chrome - works fine in IE and FIREFOX, just not working with Chrome? Is there a fix for this?
you can see here: http://puravidaguide.com/event/expresso-live-wednesdays-saquella-cafe-multiplaza-august-29th/Apr 04, 2014 02:58PM EDT
@Leighh – Still totally blank.
@Hans – You are using 4.6 here which uses the YouTube AS2 API. You should update to 5.10, it uses the AS3 API.Apr 04, 2014 02:58PM EDT
I'm having the same issue. It seemed to be working fine yesterday when I set it all up. But now my videos play fine in Chrome, but in Firefox there is just a big white box, and then a mini white box at the top left side of the page. This box doesn't show up in Chrome.
Another thing I noticed is that in Firefox, it even puts a white box in place of YouTube embedded videos. Again, not in Chrome.
Neither the main white box or the mini white box are selectable with FireBug.
(This is a YouTube embedded video which is really throwing me off)Apr 04, 2014 02:58PM EDT
This works for me?Apr 04, 2014 02:58PM EDT
