  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):

• 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.

• BlackBerry Smartphones YouTube videos do not play/Adobe Player

  I have a BB Torch 9810 and I tried to play YouTube videos and it says I need to update my Adobe Flash Player but when I arrived on the site of Adobe Player it says that the update is not supported by my "operating system or browser." What should I do?

  First, very few phones that support Adobe Flash, at least you're in good company.  If you go to the mobile site of youtube, you should be able to view videos.  It is found by typing m.youtube.com on your phone's browser.

  I hope that clears things up for you.

• YouTube videos do not play

  Videos YouTube played well in Firefox yesterday, but not today. I get a perpetual circle of loading on a black screen. If I hover over that bar below it show me miniature captures video that I move my mouse to the; Similarly, if I drag my mouse while holding down, it'll show a horizontal grid of thumbnails, superimposed on a bigger picture.

  Chrome still plays the videos very well, so I don't know isn't a plugin problem or it could have an impact on Chrome also. Plugins are all updated, for what it's worth. Was already using the latest update of Firefox before that, also.

  I copied the above from another author of the question, because it described exactly the problem I have. I deleted the cache and cookies, I tried Safe Mode, nothing works. The videos play fine on Chrome. I installed the addon for HTML5, does not solve the problem. Any suggestions?

  If you have any problems with the current versions of Shockwave Flash plugin then check this:

• Fix for Youtube: an error has occurred. Please try again later. or Youtube videos do not play.

  Try this solution.

  1. Disable or remove the addon "Video DownloadHelper". (Tools > Addons > button click on turn off or delete Video DownloadHelper)
  2. Restart Firefox.

  I tried to find an acceptable solution for several days because I had this problem. This solution worked for me. I posted the question as a solution, hope it helps someone. Addons can also create problems.

  qquito and a few others who have had the same problem, have been provided a solutions of workarounds like the decommissioning of the version of flash player. There is no need for a version of Flash Player. There seems to be a conflict between the new version of Flash Player and Video DownloadHelper.

  Thank you.

• I have firefox 13 and 15 but realplayer download this video option does not work, extensions to save plugin is disabled, if no videos do not play in youtube

  I have Firefox 13 and real player 15, but the download this video option does not work, under extensions to save browser plugin is disabled, but if active videos do not play in youtube, error occurs, it's major drawback, it works well with IE, but I prefer Firefox so any help to rectify the issue is appreciated.

  One possibility is to upgrade to Flash 11.2 and re - activate the Plugin RealPlayer browser Record extension in the Add-ons Manager (Tools > Modules > Extensions) (it's a softblock).

  If you need to return to 11.2 Flash you can download Player Flash 11.2 through this direct link:

  • http://fpdownload.Macromedia.com/pub/flashplayer/Current/Licensing/Win/install_flash_player_11_plugin_32bit.exe

  You must uninstall version 11.3 Flash.

  If it happens again then the first to try is to reload webpages and ignore the cache.

  • Press 'Ctrl + F5' or 'Ctrl + Shift + R' (Windows, Linux)
  • Press 'Cmd + Shift + R' (MAC)

  Hi Sarah!

  I solved it! I had to use the original URL shorter links to create

  functional hyperlinks or try to short the links using Google URL Shortener.

  I don't know why it worked by doing this, but he did!

• Videos will not play if Adobe Flash is installed

  I've always used Adobe Flash and never had a problem with it.  When I installed the latest version several months ago, I discovered that videos would not play at all. It's not fair, You Tube either; This is a site I visit. Six months of treaty which was too good, so I uninstalled, went online to look for an alternative and guess what? Playback of videos very well at MOST sites.  Others say that I need to install Flash Player.

  It is confusing, especially since I have no idea why this is happening. At the moment I haven't installed Flash, but I need to solve this problem. Any help would be appreciated regarding ideas, recommendations etc. Thank you.

  YouTube is almost finished with the move to HTML5 (MP4). The reason thay did it must be accessible to viewers to phone and a tablet that cannot use Flash. JavaScript in their pages determines whether a browser has Flash Player, and if it isn't, the page will display the video in HTML5. That's why you see what you're doing here. NOT all websites have done however. Yahoo working on it, just like Hulu, Dailymotion and others. NetFlix is spent reading, which causes its own problems, if you have not INSTALLED SilverLight.

  Add to this mix, Microsoft has published (without any "real world" test) IE 11 almost two months (October 18) and it has been a nightmare to say the least. Pages/Sites do not recognize because they threw a code in it, and... If a page or site may not recognize the browser, he certainly does not plug-ins that it uses. No problem for the HTML5 video that does not require the player, but Facebook Pogo games and many other Flash sites require a browser and plug-in that the code acknowledges.

  Is your browser accidentally IE11?

• After the upgrade to 16.0.1 some just Youtube videos won't play. They work perfectly in Chrome.

  After the upgrade to 16.0.1 some just Youtube videos won't play. They work perfectly in Chrome.
  A few examples:
  http://www.YouTube.com/watch?v=rQpldNJXuP0
  http://www.YouTube.com/watch?v=-e-BRki7gwU
  Most of the videos works perfectly, so I can't say what the problem is.

  I have tried so that the first thing, but it didn't work at all.
  Anyway, I solved the problem in the meantime by uninstalling Firefox and put it back. Please note that I had to do a CLEAN install, and I mean by 'clean' that I had to remove the settings as well. First I tried to reinstall it but I kept the settings (Firefox will ask if you want to keep when you uninstall) and it did not work. I therefore saved bookmarks and uninstalled everything. The later resettlement has solved the problem.
