Firefox can not play videos in the site

Firefox is unable to view the videos on this site while others can browser (opera chrome 22, 33, that is to say 11).
I tried to restart with add - to disable, but no help.

Firefox uses the Flash Player, or maybe HTML5 Media Player?

You see the Shockwave Flash plugin context menu if you right-click?

If Flash is not used you can try to disable the HTML5 Media Player by setting these false prefs on the topic: config page.

  • Media.DirectShow.Enabled
  • Media.Windows - Media - foundation.enabled

  • Firefox can not play videos, download files or run updates

    All of a sudden my browser isn't more videos. Firefox tells me my ins plugg java are blocked because there are unstable, but I can't update. later I noticed that I can not download files or run updates. What could be the cause of the problem?

    I already tried other things: System Recovery, deleted temporary files, etc. I received an alert from avira anti virus, but this doesn't seem to be a dangerous virus that is causing the problem more I received this alert a day after the trouble started.

    I don't have access to another computer to download files or updates and transfer... No idea what could be the cause of the problem, it would indeed be the java plugin? and how to solve?

    It turns out that it was a problem with the router/modem, nothing related to malware. I did not know before, but my phone could not also download new applications or updates and a friend's computer had the same exact problems once connected to the network wireless home.

    Not quite sure what caused her but restarted the modem and the router and everything works again.

    Thanks for your help anyway, if tried my phone earlier, maybe I would have thought it more early then

  • Hi, thanks for making me signed in - finally. Now, after the upgrade to the latest Firefox, I can not play videos. Addons & pluginns all turned on and up to date.

    I was struggling to connect to the support site yesterday and while this problem has been resolved, I was advised to upgrade to the latest version of Firefox from the system noticed that I was using an old. I was using Firefox 33 without major issues or problems at all. However I went ahead with the update, which gave me the 34.0.5 version. If good so far until what I went to play some of my regular TV series, I had followed with the previous version, only now he would not play at all.

    I know these TV series, comming from abroad might contain some harmful content to my machine or others, but I am well covered and as I say earlier they were playing fine in the previous version of Firefox. Just earlier the same day.

    I will be grateful if you could throw some ideas in this.



    HI Juanverano,
    Is not a problem, Mode safe mode disables acceleration addons and hardware. If this continues and it is not an add on what will be the next step to try to disable acceleration:

    Try disabling graphics hardware acceleration. As this feature has been added to Firefox, it has gradually improved, but there are still some problems.

    You will have to perhaps restart Firefox for it to take effect, so save any work first (e.g. you compose mail, documents online that you are editing, etc.).

    Then perform the following steps:

    1. Open the Firefox Options (Preferences on Mac or Linux) as follows:

      • In Firefox 29,0 and above, click on the menu button

        then select Options Preferences on Mac or Linux, or Windows.

      • In 28.0 Firefox and earlier versions, click on the Firefox orange upper-left button, then select the 'Options' button or, if there is no button up Firefox, go to tools > Options.
    2. In the window of Firefox Options (or preferences), click on the Advanced tab, and then select general.
    3. You will find in the list of parameters, the checkbox use hardware acceleration when available . Clear this check box.
    4. Now restart Firefox and see if the problems persist.

    In addition, please check the updates for your graphics driver by following the steps in the following knowledge base articles:

  • Firefox can not play Netflix, but can chrome.

    I have Firefox installed 13.0.1 (also tried the beta version, 14 or what) and I can't play movies on Netflix. Silverlight is up to date, everything is up-to-date, but it does not work. It goes to this page that says:

    "Finish the required system configuration".

    To watch instantly, yougot to a computer that meets the following minimum requirements:

           Windows XP with Service Pack 2, Vista or Windows 7
           Internet Explorer 6.0 or higher; or Firefox 3 or higher; or Chrome 7 or higher
           1.2 GHz processor
           512 MB RAM
           An Intel-based Mac with OS 10.4.11 or later
           Safari 3 or higher; or Firefox 3 or higher; or Chrome 10 or higher
           1 GB RAM
       Chrome OS
           A Google Chromebook with Chrome OS 13 or higher"

    But if I open and try it in Google Chrome, it's fine. I'm on Windows 8 Preview Release, and it is a 64-bit system. Firefox is 32 bit, of course. I don't know what else I could try to get Netflix to work in Firefox. Chrome is very good, but Firefox is my default browser, and I wish I didn't have to spend every time just for Netflix.

    Until taken netflix supported by Windows 8, the solution is lie. I must say that we are still using Windows 7 to netflix.

    If you are not comfortable with the technical stuff, an easy way is to install this addon:

    And in the field, he provides his screen option type in "Windows NT 6.1", less citations. This corresponds to Windows 7.

    If you do not feel as still having an other addon installed, you can simply add the information directly in firefox.

    Open a new tab and type in about: config. You will probably get a warning to about playing with the settings.

    Once you right click and select new > string. For the name of the preference you want to type in "general.useragent.override", less citations.

    So you want to type the value, which is the info that firefox tends more to the netflix server to be identified, mine is (at least this is what I'm saying netflix):

    Mozilla/5.0 (Windows NT 6.1; rv:13.0) Gecko/20100101 Firefox/13.0.1

    It breaks down as follows:

    Mozilla is basic info, 5.0 is the version of Mozilla.

    Windows NT 6.1 is your version of windows (Windows NT 6.1 is Windows 7).

    RV:13.0 is the version of the rendering engine Gecko used.

    Gecko is the name of the layout engine.

    The string of numbers after the date of construction.

    Firefox is the name of the browser.

    Finally, 13.0.1 is the version of the browser.

  • Can not play videos Quicktime in Snow Leopard - no plugin available

    There is no plugin available for OS 10.6.8 Quicktime (Snow Leopard). How to view movie trailers who keep telling me that Quicktime is not installed?

    When you select:

    Firefox-> Preferences (Mac)

    Tools-> Options-> Applications (Windows)

    you will see a list of the requests for assistance that Firefox uses to the opening of other content. In the list in the Action column, you will be able to choose an action for a specific file type. For type .mov files, if your Quicktime Player appears as an option in the list, try to select "Use Quicktime Player", and then restart your browser.

    If she does not appear in the list, try to select always 'request', and then later questioned, should be an option "open with...". "and then you can navigate to the Quicktime program to select on your computer.

    Once you have used an external program like this, Firefox will remember your choice and it must appear in the Options-> Applications column. Then, when you click on a link to a file with the extension .mov file, the file opens in Quicktime Player, rather than trying to use the plugin.

    Some sites to look for signs in your browser of the Quicktime plugin and are .mov files if the plugin is not detected, which is unfortunately wrong programming of their share, but you can leave your comments on these sites.

  • can not play video.

    Hey, I can't play a clip I have downloaede on my computer. can u help me?

    Hey, I can't play a clip I have downloaede on my computer. can u help me?

    Watch your video. The last 3 letters represent its file extension (file format).

    Windows Media Player supports only a handful of file formats. Here is the list:
    Video files: .asf, .avi, .dvr-ms, .m1v, .mp2, .mp2v, .mpe, .mpeg, .mpg, .mpv2, .wm, and .wmv

    If the format of your video file is not on the above list, Media Player will NOT play it.

    You hae 2 choices:
    1 Google for a FREE video converter and it allows to change the format of your video. I highly recommend to choose the WMV file format. It is a most reliable and foolproof format for Windows.

    2. install a 3rd party media player called VLC. It plays virtually all formats, and it is also free software.
