Firefox 4 not playing quicktime properly on OSX 10.6

When I upgraded to Firefox 4 on my iMac, OSX 10.6, it no longer played QuickTime video or audio properly. The symptoms tend to be inconsistent. Sometimes the audio would play but not the video. Sometimes the video would play but blink off and on with a white screen. Mp3 files will not play at all on some occasions and will play partially on others. When I removed Firefox 4 and reinstalled 3.5, everything worked fine again. Anyone have a suggestion?

I see that many have this problem. Does anyone have a workaround or resolution?

  • Firefox does not play quicktime

    Hi
    Two days ago, the quicktime on firefox stops working - i only see the quicktime icon (clock like) with ? in the middle. Please help .
    Thanks.

    Which version of FF are you using?
    QuickTime Preferences > Advanced > MIME Stettings > Miscellaneous.
    Deactivate the "Flash Media" option.
    This tells the browser not to to display Flash Media and lets the newly installed Adobe software work its magic.

    If the above thread doesn't help, try this...
    Last but not least: Thanks to QuickTimeKirk........
    Quit QuickTime.
    Open User (Home)/Library/Preferences and delete any .plist file with QuickTime in its name. Don't worry as a new one will be created.
    Open System Preferences/QuickTime and see if the window and tabs work as they should.

  • Safari 6.0.1 will not play QuickTime Files

    I am having problems with Safari 6.0.1 playing back QuickTime Files. I reset safari and cookies and it will still not play QuickTime movies. To the best of my knowledge, QuickTime is working with all other components of the computer.
    Is there a way to redownload Safari or repair it...
    I could not find a place on Apple's webpage to redownload it.
    I am using Mac OS 10.7.5 on a MacPro (2008).
    Does anyone know how to resolve this problem?
    -M

    From your Safari menu bar click Safari > Preferences then select the Extension tab.
    If there are any installed, turn that OFF, quit and relaunch Safari.
    There are several extensions such as DivX that can prevent QT content from streaming.

  • Safari Does Not Play QuickTime/.mpg Video, Only Audio

    Quicktime video not playing in safari. Checked new user, issue persists, it's a system wide issue. All the settings are right. Worked before. Still works in Firefox and other browsers. Repaired permissions. Even video on the Apple site does not work. Flash still works, windows media content still works via Flip4Mac. I was just wondering if anyone discovered an easy fix for this issue. I don't feel like doing the archive and install (preserving) or re-imaging it. Everything is up to date except for the security update and itunes. Just stopped working tonight though, not right after I did the last updates. As I said. I know the traditional way to attack this, and even a couple time consuming non traditional ways. What I am looking for here is the quick fix (if there is one). Thanks.

    Well, since we are all using different versions of Safari but the same version of QT, I headed over to the QT forum and found this - which seems to work for me.
    I just dragged the file to the desktop, tho.
    "I removed the QuickTime Plugin.webplugin.
    Mac HD > Library > Internet Plug-Ins
    1. Drag QuickTime Plugin.webplugin to the trash.
    2. Relaunch Safari and the QuickTime video that was not playing previously.
    3. The video portion should now work."

  • Firefox will not play .ogv video files when loaded from a server. Does anyone have any answers that will fix this?

    I've read the suggestions for fixing this, and none of them work. I've updated my .htaccess to match MIME types for .ogv, I've uploaded the files as both Binary and ASCII, neither method works. The .ogv file plays fine when you load it from a local file, but it will not play when viewed from a remote server. I've confirmed with my hosting company that the .htaccess and all other issues for HTML5 are up-to-date. Safari and Chrome play the HTML5 videos just fine, but Firefox will not. Does anyone have any concrete answers as to what the problem is. I'm also serving up the video files as .webm and .mp4, but neither of these formats works in Firefox either.

    That can happen if the server isn't configured properly to send the files with a by Firefox supported MIME type.
    *https://developer.mozilla.org/en/docs/Properly_Configuring_Server_MIME_Types
    Did you check via the Web Console which headers Firefox receives when requesting the .ogv file?
    If that is OK then it is possible that the file is using an unsupported coding method.

  • My Itunes does not play quicktime

    I have the latest Itunes software version 10.6.3 but when I go to podcasts and try to play video, it tells me that my version does not support quicktime. Help! I have tried updating it but it does not seem to work.

    Try relaunching iTunes in 32-bit mode first, as per the instructions in the following document:

  • QuickTime X does not play QuickTime Broadcaster recordings

    This is a post I'm leaving for other SL upgraders who come looking for information on why their QuickTIme Broadcaster .mov files and other QuickTime files such as .m4v for iPod that don't play on QuickTime X but do play on iTunes and QT 7.
    I'm finding there are compatibility issues with QT X not playing files that were created with Apple utilities such as QT Pro and Broadcaster. This has happened with both iPod .m4v and Broadcaster .mov files. Sometimes you just get a plain black window with signature Apple rounded corners and other times you get that plus audio only. YMMV
    Another point of pain is that the previously viewed URL list seems to not be remembered in QT X under some conditions that I cannot reproduce easily. QT 7 picked up the list from my Leopard install just fine however.
    As noted elsewhere in this discussion forum, the solution is to open the QT X player Info window and check the 32-bit mode so QT X does not take advantage of any of those features of your hardware or OS.
    IMHO the idea of a clean player is fine. The implementation leaves much to be desired and at present, is a wart on an otherwise trademark excellent step in a smooth OS evolution to 64-bit by Apple SW engineers. I doubt the QT X problems are engineering ones but rather product management decisions that prevented adequate resources be but on the component. Looking forward to SL releases that make QT X as invisible in the OS as it's window borders.

    For those with a similar problem, I read somewhere on the Apple forums that Metadata Hootenanny will add chapter tracks that appear correctly in QuickTime X. http://www.applesolutions.com/bantha/MH.html
    I can confirm it works for me!!!! The chapter tracks show up in Metadata Hootenanny just fine, so it’s a matter of importing the file and saving it again with Chapter Track enabled. Yayayayay!

  • Final Cut Client not playing Quicktime

    I have an end user trying to use FCS on a PC. The QT movies play for almost 2 minutes and then stop. This is true for multiple clips. She has FCS properly installed with IE*, Java 6 and QT 7.6.2. These clips work on my PC and others PC's. Any suggestions as to why they will not play just that machine? I am reinstalling QT as we speak.

    May be the problem is on the windows system on that computer, if it is possible, try to reinstall windows system?

  • Quicktime 7.2 will not play Quicktime Movies

    Ironic isn't it.
    I recently purchased Sony's Movie Studio and it required a new(er) verson of Quicktime to import QT movies. So I download 7.2 ( i had 7.01, if I remember correctly) and installed it. I can now import QT into Vegas for editing. Fine. Great.
    BUT, and here is the ironic part, Quicktime will no longer play Quicktime movies! Not .mov, .mp4, nothing. Zip. Zilch. But it will play some old avi files for some reason. All I get is the audio and flashing striped colors. Until 7.2 I could load any .mov, avi, mp4 file and edit them without a problem. (I forgot to mention, I had QT Pro) I was also using Any Video Converter to convert old home movies I'd burned to dvd to the mp4 format, and Quicktime worked flawlessly to open them too. Up until this "update" I've been very happy with the performance of Quicktime.
    Now, nothing but frustation and the online Support hasn't pointed to a solution. And yes, I have updated my Dell PC running XP to all the latest service packs.
    Any ideas? If I delete 7.2 I could probably re-install a version of 6 Pro that always worked, but then Vegas Movie Studio won't work. Kind of a Catch-22. Thank you for any help.

    It has helped some who have had this problem. Try dragging the QuickTime webplugin folder to the desktop in case you need to put it back and see.

  • Firefox does not play videos online except on YouTube. I have the latest updated flash player . What is the problem ?

    The videos do not play except on YouTube. It shows an error message that it can't play the video. I have the latest updated Adobe Flash player. And the same videos work well on IE and GC !

    Start Firefox in <u>[[Safe Mode]]</u> to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
    *Don't make any changes on the Safe mode start window.

  • Firefox will not play training videos from BMW university

    I need to use BMW university (ICP) to view training videos. I use Linux (Linux mint 9) and Firefox. I can view them using the computers at work which of course are windows and have internet explorer. I have emailed BMW about this but they seem to be unwilling to change anything. Anyway. I use Adobe flash and Sun Java, the latest versions and have all the correct plugins. Firefox will work on every other site. I tried using Opera but I got an error message saying my Browser doesn't use Dynamic html, so I quit Opera. I love using Firefox and would love to have it work on this site. I can't give you the URL for the site as it is protected and the property of BMW. I don't know what to try to get it working, maybe it will never work, maybe there is proprietary windows stuff built into the site and it just wont work with Linux or Firefox.

    What kind of content is that?<br />
    Are that Flash videos?
    You have the Flash player, so if it is Flash then it should work.
    Which player do you see if you right-click on it in IE ?

  • Firefox is not loading websites properly on our mac.

    Firefox is not loading banners/background images/various interactive buttons etc on '''all''' web sites: I'm using Firefox/3.6.12 on Mac OS 10.4.11
    Other browsers are fine: ie Safari and Opera.
    Firefox is working fine on our PC.
    I have taken screen shots of Google home page and Firefox home page in Ff and Safari to illustrate this point and can email these to you so you can see what's happening. Ff was working fine yesterday.
    Entering extra information as requested I've noticed that the Default Plugin is showing as disabled in the Technical info under the Trouble shooting menu but is showing as enabled in the plugins list in the Ff drop down.
