Many youtube videos will not play in Firefox - I get the error message - "no video with supported format and MIME type found"

this is a recent problem - the videos play in Chrome and Explorer, but not in Firefox

This happens if Firefox uses the HTML5 media player and can't play the media file.

No video with supported formate and mime type found

I am able to view videos on all but 1 website: http://www.start-american-sign-language.com/free-sign-language-asl1.html
When I view that page, the video box only shows the x with "no video with supported formate and mime type found" being displayed.
I have updated to the most recent palemoon (25.3.0) and have the following plugins installed
DRM 9.0.0.4503
Shockwave flash 16.0.0.305
Silverlight 5.1.30514.0
VLC Web Plugin 2.2.0.0
Windows media Player Dynamic Link LIbrary 3.0.2.629
I have cleared my cache and cookies, and am unable to view the video in question. If I go to https://www.youtube.com/html5, it indicates that I have an operable Webelement player and Web VP8, and all others are exclamation points.
Does anyone know why I can't watch the (mp4) video(s) in question? I have turned up no viable solutions using the forums or google.
Thanks!

This happens when there is no support in your Windows XP version to play any of the media file formats that the website offers with the HTML5 media player (i.e. not a Flash player is used, but a video tag).
That are MP4 files with type="video/mp4"
*VLC shows: Codec: H264 - MPEG-4 AVC (part 10) (avc1)
You might be out of luck on Windows XP and your only option would be to use an external media player and paste the links in its location field.

Trying to embed a video file in HTML5: ERROR=No video with supported format and MIME type found?

Hello all!
I am desparate for a solution. I am testing my site on Firefox and Explorer and still no sign of a functional video yet.
Firefox: I get the error: No video with supported format and MIME type found.
Explorer: I just get a distorted layout.
Here is the code I am working on:
<table id="Table_01" width="480" height="801" border="0" cellpadding="0" cellspacing="0">
    <tr>
        <td colspan="6">
            <img src="images/Video_01.jpg" width="480" height="114" alt=""></td>
    </tr>
    <tr>
        <td rowspan="3">
            <img src="images/Video_02.jpg" width="52" height="486" alt=""></td>
        <td colspan="4">
           <video controls width="376" height="221">
             <source src="C:\Users\aalmeida\Videos\AEMC PEL 103 6 Channel, Power & Energy Logger - with Display (Part 1).mp4" type="Video/Mp4"/>
             <source src="C:\Users\aalmeida\Videos\AEMC PEL 103 6 Channel, Power & Energy Logger - with Display (Part 1).webm" type="Video/WebM"/>
             <source src="C:\Users\aalmeida\Videos\AEMC PEL 103 6 Channel, Power & Energy Logger - with Display (Part 1).oggtheora.ogv" type="Video/Ogg"/>
             </video>
Please tell me that there is something missing in the code. I have spent a lot of time uninstalling-updating Firefox plugins, added MIME types in the Internet Information Manager (I'm on Windows 7)
and seriuously hit a dead end with this!
Any advice would be muchly appreciated!!!
Thanks

As Jon said, you must declare the page as HTML5.
And your server may not be set up to deliver video as a binary file if it is an .OGG file. I have not seen this problem with .MP4 or .M4V in the past, but every server is a little different.
To add a MIME type, you need to change your .htaccess file on an Apache server thusly:
AddType audio/ogg .oga
AddType video/ogg .ogv
AddType application/ogg .ogg
AddHandler application-ogg .ogg .ogv .oga
Additionally, MIME types can usually be changed on a server's Control Panel. One can also ask one's hosting provider to do this as well.
Firefox makes it necessary to use OGG files. Webkit-based browsers will deal with .M4V or .MP4 and I understand Internet Exploder will work with the latter two as well.

No video with supported format and mime type found since upgrading to FF 36.0 in Linux

Unlike others with this problem I just started experiencing this after an upgrade to 36.0 and instead of Windows I'm running Ubuntu Linux however I'm not running the 'Ubuntu version'.

I'm trying to play a video but it does not work or load up, issue? No video with supported format or MIME type found issue in Firefox 28.0 Windows vista

no playback of videos -latest flash player installed and updated add-ons but it still dosn't work. only youtube works but no other site.

Will you not post the link to the video like I requested, or at least let us know if you can play the videos on the pages I linked to? It would prevent more random guesswork.
Firefox doesn't try to play files it can't handle. When coming across a direct link to a file that could be handled by a plug-in, but that plug-in isn't installed, Firefox would display a download prompt.<br>
That's not the issue here, where there's an unsupported format error. That suggests an MP4 file that can't be played. Even if a plug-in that can handle MP4 files were installed, Firefox probably wouldn't use it due to bug 861090.
Firefox has supported HTML5 H.264 video on Windows Vista since version 22.0. There's no point in installing the very old — and likely abandoned — Windows Media Player plug-in.

After installing a new version of Firefox, I get the error message "The procedure entry point JS_GetOperationLimit could not be located in the dynamic link library js3250.dll" when I try to start firefox. Elsewhere in the forum a complete reinstall is suggested; however, I can't do that because of my company's IT policies. Is there any way to solve this problem WITHOUT a complete reinstall? Thank you!

If you can't reinstall Firefox yourself then you need to contact your IT department and ask them to check the Firefox installation.
It is possible that some files got broken with the latest update.

I find the Air easier to work with if I need a keyboard if, for no other reason, that's more compact to carry around than the iPad and a keyboard, even one that is part of an iPad case. I also often have to access data from one application when using another, and iOS is not at its best when having to do rapid application switching (Command-Tab switching is a lot faster than the double press home, scroll the icons at the bottom and swap).
As well, for editing I find the lack of sandboxing on OSX allows for efficiency enhancing utilities across applications, something you don't get in iOS. I understand the reason for that, but while more secure it also creates issues of its own in terms of usability in a number of situations.
I prefer the iPad for totally single application focused situations where little or no input is required. I use my iPad to hold copies of manuals when I'm doing a full day continuing education presentation for CPAs. A MacBook Aire can't really fill in very easily for that usage.
I see them each as tools appropriate for different jobs.

I can not update CC aps - I get the error message regardless of the ap being update

I can not update CC aps - I get the error message regardless of the ap being update: There was an error downloading this update. Please quit and try again later. Error Code: U43M1U49
I have been trying to update a set of aps for a few days - never works. I've tried sitting with the machine and monitoring the progress. I've turned off my McAfee firewall.
Any suggestions?
Thanks

You must be connected to wifi.
iOS will not update over a cellular connection.

When I try to start Firefox, I get the error message "Your computer must be restarted to complete a previous upgrade of Firefox. Do you want to reboot now?" I have rebooted several times to no avail. Get the same message when I try to uninstall Firefox

Just had this same problem. Based on other suggestions I found on the web, went to C:\Program Files\Mozilla Firefox and deleted all files that ended with upgrade and/or delete. Then I was able to uninstall Firefox and then reinstalled. Hope this helps!

Videos will not play in Firefox. They either don't play at all or they will play for 20-30 seconds and then stop.

videos will play in the safari browser with no problems, but will not play using the Mozilla browser.

On what website are you having this problem?

Video will not Play in Firefox 7.0.1

I was getting a blank screen and video would not play. I tried URL Below in IE Explore 32bit and 64bit and video played fine.
I first disabled Flash Player in Firefox went to http://www.weather.com/weather/videos/news-41/top-stories-169/cat-stares-down-mountain-lion-22257 video !
Video would still not play. So I went to control panel in Windows 7 Ultimate 64bit Programs and Features and removed Flash Player, Note there where several version, one was 10. something and the newer one 11.0.1.152. After renewing I again went to link above and was advised I needed to install Flash Player. I re-Installed from Adobe and verified that it was installed in Windows and received no video again. Note there are 2 versions installed one for 64bit and one for 32 bit but both have almost the same name. One has X64bit and the other has 64 bit. It is noted at Adobe the 64 bit contains both 32bit and 64bit install. I still can view video after re-install in IE 32 and 64 with no problem. Same thing happens at this URL that I view all the time http://www.ky3.com/weather/ video is under Latest Video Forecast. It plays in IE fine.

Streaming flash video will not play automatically. Must move the mouse off the link

I have 4 computers, all running Win7. On every one, Internet explorer. 2 have firefox 3. 2 have firefox 4. When clicking a link on a website that has live streaming video (flash) - the stream changes to the next one and the video feed begins right away. Works fine on all 4 computers in IE, and in both Firefox 3. The video starts when the mouse is clicked, or when the screen is refreshed. On both computers with firefox4 - the mouse click loads the new feed, but the video hangs on a white screen until the mouse pointer moves. same problem when the feeds are set to auto-rotate. they load every 30 seconds, but unless I physically move the mouse, no video plays (or click the 'next feed' button again, which gives a split-second peek at the video feed I am navigating away from), I need to monitor many security cameras, and this is excruciating. Safe mode does not help. I have the newest versions of everything. please tell me this is a bug and not someone's bright idea

HT1414 upon updating to ios 7.0.2 all my gopro black hd videos will not play they show as gray in colour. Are these files still there and can they be restored they ran perfectly until the update

upon updating my ipad to ios7.0.2 all of the go pro black videos show as gray and when you click on them they come up first frame but will not play. can they be restored or are they lost. they played perfectly in both i movie and camera role before upgrade.

I'm searching for an answer to almost the same exact problem, using almost the same exact hardware and software. Has an answer been found?
The files that I'm trying to burn come from eMusic, and they are formatted mp3. Recently, (after the iTunes update to 9.2.3?,) they would not drag and drop from iTunes into Toast. From several different discussions I've tried working around this by dragging to the desktop first then dragging and dropping to Toast, going to Toast from a programmer's homemade help window, " iToons," and today, after talking with Apple support, going directly to Toast from my eMusic folder. Alas, all recordings do not perform like they use to. Sometimes they play and sometimes not. There is one I managed, that is listenable, but sometimes I have to put it in my car stereo over and over again as it gets ejected with an error code, sometimes, finally it takes it... Some of the recordings on other disks I've burned are not clean - they have white-noise sounds creeping in... I use to have none of these problems. One time as I was listening to a CD that managed to play, and it just stopped playing... Is there an answer out there to get back to how it use to be? Thanks for you help.
