Firefox is suddenly only playing the sound and a distorted mess of color where the video should be

I usually have no problems with watching flash video on my computer but out of the blue it now only plays the sound without error and displays a mess of indistinguishable colors where the picture should be

The Reset Firefox feature can fix many issues by restoring Firefox to its factory default state while saving your essential information.
Note: ''This will cause you to lose any Extensions, Open websites, and some Preferences.''
To Reset Firefox do the following:
#Go to Firefox > Help > Troubleshooting Information.
#Click the "Reset Firefox" button.
#Firefox will close and reset. After Firefox is done, it will show a window with the information that is imported. Click Finish.
#Firefox will open with all factory defaults applied.
Further information can be found in the [[Reset Firefox – easily fix most problems]] article.

Can somebody tell me why firefox wont play a video (Mp4) but if I download it and play it on my computer and go back to firefox it will then play the video?

None of the videos on this site would play... http://www.meipai.com/media/103870328 Until I download each video and play it with windows media player. I can then go back to Firefox and the video will play. I have been going nuts trying to figure this out and lately I have been very disappointed with Firefox. I have messed with application content types, reset browser, tried in safe-mode, uninstalled and reinstalled with NO apps and more. Please help, I really want my Firefox back. ; )

Thanks for your help... I'm using "Flash Video Downloader" add-on.
Not all the videos will play in firefox after I download them but about 90% will.
This is one that wouldn't play and I downloaded it, played it, deleted it, and went back to firefox and it will now play??? Very strange? http://www.meipai.com/media/120179641

I uploaded 3 audiobooks from iTunes to my iPhone 5 with the latest ios7 on it. Each of them only plays the first 15 mins of the playback and then silence, the bar shows the book is still playing but no sound, any ideas? Thanks

What happens when playing the same books in iTunes. Is there sound after 15 min?
If also silent in iTunes, check the info tab where you can see the item is an audiobook, etc. Check the volume bar, this normally is on the zero point.
When an audio book is really low in audio, I tend to move this to the plus side (+1=max), but for some strange reason this bar was at -1 in some books I had and they also seemed to play in absolute silence.

When i start Firefox ( 5.0.1 ) it loads the home page fine but along with it, it starts playing a video i watched earlier on youtube and it is invisible ( no where in tabs ) and i can just hear the sound. After playing the video one time it stops.

Sorry you are having problems. First of all try Fifrefox's safemode.
*[[Troubleshoot Firefox issues using Safe Mode]]
If that works post back for further advice.
Next step, if safe mode did not work.
First: Try a clean install, (you have had a none standard version installed previously) that involves deleting the program files. Then if necessary try troubleshooting by creating and using a clean empty Firefox profile.
See
* this recent post [/questions/940399#answer-377134]
* http://kb.mozillazine.org/Standard_diagnostic_-_Firefox#Clean_reinstall
Second: try a New Profile
*http://kb.mozillazine.org/Profile_Manager#Creating_a_new_profile
* this will be an additional profile, it is still worth backing up any existing or currently working profile on a regular basis
**[[Back up and restore information in Firefox profiles]]
* Until you are absolutely confident about the repercussions I suggest
** always use an empty folder when creating a new profile
** never delete or rename profiles, just disable or remove shortcuts
** after creating a new test profile open it and check for any addons or plugins that may be have been included by default

A Video Site I've Gone To For Years (Liveleak), Never With Firefox, When I Click To Play The Video, Downloads Box Pops Up And Says I'm Downloading The Video.

So I Go To The Site, Everything Loads Properly And Quickly, Click The Video I Want To Watch, That Video Page Comes Up, Once Again, Quickly And Properly. So I Click The Play Button To Play The Video And The "Downloads" Box For Firefox Pops Up And Shows That I'm Downloading The Video. That's Great If I Want To Download The Video, But I Don't, I Just Want To Watch It There On The Site. I Just Now Downloaded Firefox Because I've Heard So Many Great Things About It. This Site (Liveleak) Was The First Site I Went To After Downloading, So It's Of To A Bad Start With Me For Firefox. This Site Works Fine In Internet Explorer No Problems Whatsoever, So Its Not The Site.

Sounds that you are missing the plugin that is used to play those videos embedded in Firefox. 
Your system details list doesn't show any media player plugin, so you will either have to check if the plugin(s) are installed, but disabled or install missing plugins.
*https://support.mozilla.org/kb/Popular+plugins
You may need the new WMP plugin (np-mswmp.dll) because Flash always uses a dedicated player to play the videos and would never offer to save videos directly unless an extension is used.

I have rented a video on my iphone but when I got to play it on the apple tv it is only playing the sound how do I fix this?

I have rented a video and when I go to play it on apple tv from my iphone it only plays the sound, how do I fix this?

if it's not iphone4s or later it does not support airplay mirror

What shall i do, if my movie only plays the sound- but not the pictures- EVEN if i have the right attitude?

I try to public my movie, but the problem i have is, that the "finished" movie doesn't play the video WITH the pictures. It plays only the sound.
What kind of attitude i have to use, to get the clip with sound and movie? Because i try these from a tutorial : Premiere Grundeinstellungen / Projekteinstellungen / Rendereinstellungen Tutorial - YouTube
and that still doesn't work.

Your question appears to be about Premiere Pro, not Premiere Elements. I recommend you contact the Premiere Pro CC forum.

YouTube only plays the audio how to get it to play audio and video

I can't play youtube videos in firefox. I only get the audio portion without the video. It was working fine. No new programs. No new plugins. No changes I can recall. How do I fix this?
I'm on Windows XP

You can check for problems caused by recent Flash updates and try these:
*disable a possible RealPlayer Browser Record Plugin extension for Firefox and update the RealPlayer if installed
*disable protected mode in Flash 11.3 and later
*disable hardware acceleration in the Flash plugin
*downgrade the Flash player to version 10.3 or 11.2

Firefox don't play video from diferent sites like hulu, cnet, cbs, abc, etc. Only play the advertising. WHY?

I try this why chrome and IE and work perfect, but whit Firefox only play the advertising.
I try restore point at my computer. Don't work.
I try reinstalling Firefox. Don't work.
That is my only problem. For the rest Firefox work just find.

I have to correct something. With type="video/quicktime", Safari 7.0.1 does play the QuickTime VR Panorama, so it's effective for both QuickTime videos and panoramas. But, what I wrote about Firefox and Chrome hasn't changed.
I did get the QuickTIme with a "?" symbol when I tried to play it with Safari 7.0.1, before submitting the question; but maybe that was a side effect of an earlier attempt.

If your country's iTunes Store allows you to redownload purchased tracks, I'd delete your current copy of the track and try redownloading a fresh one. See the following document for instructions:
Downloading past purchases from the App Store, iBookstore, and iTunes Store
Otherwise, I'd report the problem to the iTunes Store.
Log in to the Store. Click on "Account" in your Quick Links. When you're in your Account information screen, go down to Purchase History and click "See all".
Find the item that is not playing properly. If you can't see "Report a Problem" next to the item, click the "Report a problem" button. Now click the "Report a Problem" link next to the item.

Since syncing my Ipod classic three days ago, the songs will only play the first three minutes and five seconds. Then it just stops. After a little while, it moves on to the next song.

I have an old iPod Classic, 5th generation with video 30 GB. I sync via a pc. Since syncing it three days ago, the songs will only play the first three minutes and five seconds. Then it moves on to the next song or if it's the last song, it goes back to the menu. I just synced again and it it still doing it.It also has a small group of dots near the middle of the screen that weren't there before.Has anyone else had this problem or know how to fix it? Thanks.

Please disregard this question. I have a better worded version coming up.

My music is stored on iCloud and when I'm playing a playlist, it'll only play the track I choose and won't go on to the next one, it just repeats the one I selected. Any ideas please?

Hi
All my music is stored on iCloud but when I try and play music from a playlist, the iPhone 4 will only play the track I select and won't progress on to the next one. It just keeps repeating the one I selected. Does anyone else have this problem? Many thanks.

I bought a movie on iTunes and when it loads up I can only play the bonus features and not the actual film. The title screen is also glitched and merges with the scene selection. I don't think it downloaded properly. what can I do?

It happens sometimes. Delete the current copies, don't hide from iTunes in the cloud if prompted, close iTunes, reopen, download from iTunes Store > Quicklinks > Purchased > Music > Not on this computer.
While downloading click the download icon at the top right and uncheck Enable simultaneous downloads. You may find it more reliable that way.
