  Firefox is unable to view the videos on this site http://socialcam.com/ while others can browser (opera chrome 22, 33, that is to say 11).

• Can not find the downloaded file

  I regularly download files, and they will 'always' in the same directory. Now, I downloaded fedora-live-workstation-i686-22-3.iso
  of https://getfedora.org/en/workstation/download/and (a) I didn't get the usual "save/open" Download dialog and (b) I can not find the downloaded file. The < downloads - tools > FF screen displays the file as downloaded, but not (AFAICT) where he was placed.

  Any clarification would be appreciated. Thank you.

  (OP) Well, I downloaded the same file again and this time everything went as it should. For example, some of my 'facts' above must be wrong, but I don't know who. I suspect some personal deficiencies.

• can not play videos more even if I have adobe flash worked before better than chrome or explorer

  Hello

  I love firefox videos esp. Much better than the internet explore and chrome. Very stable and smooth. He played very well and then crashed. I thought it might be a few programs I uninstalled as shockwave who played hell with my computer. I uninstalled and reinstalled mozilla firefox and adobe flash player, but still could not play videos you tube, or golf revolution, etc. I took a screenshot, but I do not see an attachment to send you. It says I have to update adobe flash player or adobe flash player is required for video playback, which I have already done several times but it still doesn't appear in my firefox plugins. Please notify.

  Have you downloaded the Flash Installer via this page?

  • http://www.Adobe.com/special/products/flashplayer/fp_distribution3.html

  • 32-bit Windows: C:\Windows\System32\Macromed\Flash\

• Can not play Cyber shot files video camcorder

  I have a new touchscreen ' Toshiba Qosmio and I'm trying to find my way around it...

  I have a Sony Cyber-shot camera and used to download all my pictures and videos on my previous PC using Picasa, but I do not have this program on my Toshiba.

  I have uploaded my latest photos and videos in my images and all files are listed with their thumbnails.

  However, when I try to play a video by double-clicking, Toshiba Video Player tells me "this video cannot be played".

  Can someone tell me why this is and how I can access these files and read them?
  I'll be very grateful.

  Thank you in advance.
  AthenaB

  Hello

  Maybe you should try another video player since not all video formats are supported by Toshiba video player.

  Have you tested the VLC Player?
  Recommend to do this... the VLC Player is a freeware tool

  I also recommend to check the s manual camcorder to get some info on the format of file, then you could search for tools that would manage the file format of camcorders.

• Firefox will not play SermonConnect mp3 files that have been uploaded to Amazon S3 server using S3 Organizer after 2014 7. Already downloaded the files OK.

  Files uploaded to the Amazon S3 server are accessible via our Web site at littlecountrychurch.org. All multimedia files downloaded before January 7, 2014, be played properly on our media page. Files uploaded after January 7 refuses to play on the Firefox browser. To add to the confusion, other browsers Chrome, Safari, Internet Explorer on Windows and Mac-play these files correctly. In addition, an older version of Firefox on an XP laptop plays files correctly. We even ran a test by downloading a working of the S3 server, re-uploaded the file file and Firefox would not read the freshly downloaded file, but he continued to play the same file previously downloaded without problem.

  The problem is the content-type header sent to S3. The old MP3s are designated "audio/mpeg", which is perfect. Newcomers are designated "application/download", which does not work in Firefox native HTML5 audio player. (The inset on the screenshots is pasted from a screenshot of the Fiddler proxy).

  On a normal web server, all .mp3 files usually served in the same folder have the same content type. Something seems different about Amazon storage, perhaps based on a difference in their environment "backstage."

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

  Hello
  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.

  Concerning

  J.Verano

  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:

  • Troubleshoot extensions, themes, and issues of hardware acceleration to resolve common problems of Firefox
  • Update your graphics drivers to use hardware acceleration and WebGL

  This solve your problems? Please report to us!

  Thank you.

• 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.

  I had the first amazon. I'm going to play a video. It asks me to install Flash despite the fact Firefox support encrypted html5 video.

  If it's supposed to happen?

  The site asking me to activate Silverlight.

  No idea why Amazon's HTML5 player does not support Firefox, but cela seems to be the case at the moment according to this article:

  http://www.Amazon.com/GP/AW/help/ID=201422810

  The HTML5 player is available on the following browsers:

  • Chrome (M42 version or newer)
  • Internet Explorer (version 11 or newer)
  • Microsoft on Windows 10 edge
  • Opera (version 31 or more recent)
