  After the last update of Firefox, youtube videos do not play. The answers I've found are not relevant or too complicated.

  Hi Cbella, YouTube is generally used with an HTML5 player, who is a player who does not use a plugin video in MP4 format (for example, it does not use the Flash plugin).

  Now, I based this assertion on Windows, Mac may vary.

  Could you do two tests for me?

  Test #1:

  To verify which player you see (which does work), try a right click or Ctrl + click on the YouTube Player and check the "context menu" that rises. If it's the Flash, there will be a menu short, referring to the Flash on the last line. If you do not see that, if you get a regular menu of Firefox, it's probably the HTML5 player.

  Are what player you?

  Test #2:

  If you open the following test page, which videos to play?

  http://www.quirksmode.org/HTML5/tests/video.html

  • The video "H.264/MP4" play?
  • The video "WebM" play?

  Thank you.

  Also, you can check if your Flash plugin is up to date? You can use the site Mozilla Plugin check for this (please ignore the other plug-ins page wants you to update at the moment avoid making the situation more complicated):

• Video of youtube HD plays do not in safari

  Latest post youtube video plays do not (small wheel) in Safari.  Plays very well in other browsers (google chrome, etc...) In addition, this issue not only on my computer.  Others are experiencing the same problem.

  Thoughts?

  I have exactly the same problem. All other browser and device works very well, but in Safari, he just started playing a couple seconds and then freezes with the spinning wheel. It seems he does it just for the HD version of the video. I tried to download the video and download it again, did not help. Integration of the video on a website does exactly the same thing.

• Playlist of YouTube videos will not play always more

  I have Win 7 and FF 18.0.1 the problem I have is recent because it used to work very well.

  When I go on Youtube and want to play a playlist of streaming videos, it plays not always more. When the video page appears that it appears with a red circle "BOLD" and a backslash in it and as soon as I move my mouse over the video portion of the page the red circle goes away then I have to click on the play button in the center of the video page to play. He then played this video and stop. So I go through the same thing again to get the next video to play when all the videos should play without interruption until all are played and this is how it used to work until very recently. I'm guessing that I added a FF add on that is causing this problem. This has happened for a few weeks and I thought nothing about it until today when I tried to play a continuous loop of videos and now I don't know what to add ons that I recently added. Of course, on that I do not know that a FF throw causes this problem. I can play the same playlist of videos with Internet Explorer and they play the way they are supposed to play continuously.

  Thanks for the ideas of all. Some time has passed since I had this problem so I don't know what was the cause. However I think that it ended up being Flashblock. In any case, I noticed that I uninstalled Flashblock. I'm not sure but it seems that it's the first thing I uninstalled and it does not solve the problem. There heck of 81 and I remember even back a month ago and a half what has been done to solve this problem. Sorry about all the...

  Thanks to all those who had suggestions.

  do not load videos on YouTube, the videos that are on other sites, which are linked to YouTube also does not charge. I only have this problem with Firefox version 6.0.1. I'm not having this problem when I use (forced to use) Internet Explorer. Why is it a problem in Firefox and how can I solve this problem?

  Sometimes an extension for Firefox can block plugins or otherwise prevent audio or video content to play. If the audio or video games when you disable all extensions, then one of your extensions because of the problem.

• YouTube video plays in the left upper corner of the screen.

  Very well. The problem is that since the update for Firefox 37.0.2 I have problems playing video on Youtube.com and sometimes Newgrounds.com. In Youtube I play a lot of videos show only now in the upper left corner of the screen and the size of this video does not change even in full screen. There's the size of a small tile. I tried to disable add ons, and virtually everything suggested on various web sites. On new grounds, videos and games returned backwards and forth like the occasional video, but the video question on Newgrounds is not as bad as the issue that Firefox has with some of the games.

  I tried the games on Internet Exploder and exact same videos and I get these questions. It started to happen after the update to 37.0.2.

  I use Windows 8 (COMPLETELY up to DATE) and I have the latest version of Flash. I managed to narrow it down to a problem of Firefox and many others still reported in various sites addressing this issue as a bug in Firefox. I agree with this observation. Even my video drivers are also updated. My computer uses the Intel 4600 drivers.

  Features model relating to this issue:
  ASrock Z97 Pro3
  Intel graphics (onboard)
  16 GB of RAM

  If a right click on the drive on YouTube shows a pale menu mentioning the HTML5 player, which uses built-in features of Firefox. If she mentions the Flash drive, then it uses the Flash plugin. It would be useful to know the next steps.

  It is a standard orientation which addresses the most common issues with the Flash Player plugin. I'm sure you've seen some of it before, but just in case:

  (1) If you have any recorders/downloaders who interact with Flash media to ensure that they are as up-to-date as possible, or disable them temporarily.

  (2) turn off hardware acceleration in Firefox and Flash

  (A) in Firefox, uncheck the box here:

  "3-bar" menu button (or tools) > Options > advanced > General > "use hardware acceleration when available.

  Which takes effect the next time you exit and restart Firefox.

  (B) in Flash, right-click in the press and choose settings, then the first mini tab and uncheck the box to use hardware acceleration. More information in this article from Adobe technical support: http://helpx.adobe.com/flash-player/kb/video-playback-issues.html#main_Solve_video_playback_issues

  (3) turn off mode protected (Windows Vista and later)

  The functionality of the safe_mode of the Flash player plugin has security benefits, but there seem to be some compatibility issues on some systems. There is a hidden for this parameter:

  (A) in a new tab, type or paste Subject: config in the address bar and press ENTER. Click on the button promising to be careful.

  (B) in the search above the list box, type or paste the flash and make a pause so that the list is filtered

  (C) double-click the preference dom.ipc.plugins.flash.disable - protected mode to change its value from false to true.

  It cannot take effect until all the Flash was discharged for a few minutes, or you close Firefox.

• functions of YouTube works do not (such as adding to the playlist comment)

  Hello.
  functions of YouTube works do not (such as adding to the playlist comment) has stopped working, they are still working for the same account on chrome or another browser. (when it happened I didn't update or downgrade programs, addons, plugins that run in firefox or chrome, I don't see why all of a sudden).
  so I can't like videos, I get the message 'feature not available try later', can't add videos to the playlist (whole playlist including fav, as: Watch more later playlist pre made by youtube) and can't comment, for these 2 functions, I get the message 'invalid request '.
  all this happen again and many times, they stop or I can't make it work with reboot, refresh, try again.
  I did a fresh install of firefox and all it's the addons, plugins, same installation fees of adobe and divx, vlc products (which have the plugins or addons in firefox)
  After installing I could like comment add to playlist, before the snap all the addons, but I could only play HTML5 in youtube, any video that had no HTML5 support required at adobe. (after that I installed adobe it worked until I restarted the browser).
  now it does not work yet. (to disable, uninstall all the addons, plugins does not affect the problem)

  Some issues may also occur because of ProxTube - at least, I realized that I was was instantly redirected to the first film in the playlist on youtube - having no chance to see the entire playlist. It works when I disabled ProxTube.

• Windows 8 Apps (Netflix, Hulu, Youtube, TuneIn) will not leak

  Windows 8 Apps (Netflix, Hulu, Youtube, TuneIn) will not leak

  I have advanced and updated the OS on my ASUS G76VW-DS71 to Windows 8. Everything seems to work fine, except for on the thing:

  None of the applications (Hulu Plus, Netflix, Youtube, TuneIn) continuous flow actually do anything. The apps will turn on and I can select a video, but when I press on play streaming won't start (Netflix get stuck on 97%). I can listen to all the services if I use a web browser but not Windows 8 applications. In addition, the Skype app stops immediately when you try to open it.

  Any ideas is what is the cause and how to fix it?

  The Windows Firewall will allow apps to pass through. I also disabled, but it did not help.

  I solved it!

  It was my video card driver. I have an ATI Radeon HD 4870 and I * was * installed Catalyst Legacy 12.6 of driver for Windows 8. Then I ran the Windows Installer of catalyst 8 version and select uninstall to remove all driver AMD components. Rebooted as directed, and installed a Windows driver. This driver allowed video!

  Then I tried to reinstall the version of Windows 8 of the Catalyst driver - and did not yet reading!

  I'm going to do some further study and update this post.

  Update:

  The driver that Windows installs that works is "ATI Radeon HD 4800 Series (Microsoft Corporation - WDDM v1.1)", dated 19/06/2012, version 8.97.10.6.

  The driver provided by the supposed Windows 8 Catalyst driver package is "ATI Radeon HD 4800 Series", dated 07/03/2012, version 8.970.100.3000. For control purposes, I installed just the driver, not the software.

  Immediately after installation (no reboot was required) Netflix then gives an error code that there is a problem with the internet connection. Of course, the internet connection is fine.

  When I reboot, Netflix returns to its State at the death-to - 97%.

  Yes, up to what AMD Gets their act together:

  1. Uninstall your video driver using uninstaller AMD.
  2. Let Windows Installer for you.
  3. If you want other AMD software, run the catalyst on Custom Installer and make sure that the AMD display driver is not selected.

• YouTube comments are not displayed

  When I look at a video on YouTube, the comments section does not load. Comments load with other browsers (e.g.Safari).

  This has happened since the change in the policies of YouTube comment, November 2013.

  Question product Forum Google "Why can I not see all the comments on Youtube?" showed the suggestions to disable Ad Block. I have Ad Block or not see it in my modules. Is there an another add-on which could be causing the YouTube comments do not to load?

  The problem is probably caused by lightbeam.
