Sierra won't let me play youtube videos

Since I installed Sierra, youtube will not play videos.

I get a message: your browser does not recognize the video formats available.

It has a help page which States that the preferred format is HTML 5 so I don't see what can be the problem. I saw an old post that Perian can cause this problem, so I removed Perian and still no love.

Any ideas?

Thank you

Tom

Even with me in Safari, Firefox, but still works.  I installed the latest Flash from Adobe, but got the same results; Safari-Firefox YES.  Apple, we need a fix.

  • Why the latest Firefox won't play YouTube videos

    Everything worked fine until the latest version of Firefox, now I can't play YouTube videos. No problem with Chrome or IE. Firefox screwed up something with their latest version. Problem started on 09/03/15.

    1) enter the config by typing about: config in the address bar.
    (2) enter media.mediasource.webm.enabled press ENTER.
    (3) make a right click on it and change to true, for some reason any, defined as 'false', which makes the MSE & WebM VP9 does not work correctly.
    (4) visit: https://www.youtube.com/html5 and check that everything is OK.
    (5) tries to watch a video. It should work now.

  • Firefox 7 won't play YouTube videos

    Running Win7 x 64. Upgrade to Firefox 7, then YouTube videos stopped playing. YouTube keeps insisting that I have to install the latest flash player, what I've done several times ("install_flashplayer10_mssa_aih.exe" and "install_flashplayer11x64_mssa_aih" versions), clear cookies, restart and all that crap. Firefox refuses to play YouTube videos. Internet Explorer 9 (x 64) plays great YouTube videos. Don't use Firefox more. You've got to SUPPORT your application instead of users leaving Wade. It is also why I HATE the upgrade. It causes too often new incompatibilities when I just want to leave what works, the hell alone.

    The Adobe forum, someone suggested

       * go to http://forums.adobe.com/thread/909550 and
             o download the 64-bit uninstaller
             o download the 64-bit installer
       * close all browser windows, then run the downloaded uninstaller
       * restart Windows
       * delete any remaining files in
             o C:\Windows\system32\Macromed\Flash
             o C:\Windows\syswow64\Macromed\Flash
       * now run the downloaded installer
    

    It still does not work. Then someone else said to install the ActiveX Installer, I found somewhere online.

    THEN finally it worked. But I still don't understand why I have to jump through additional hoops, which are not explained in the first place-YT says I need to upgrade (even if my old machine W2k with FF 3 and Flash 10 works fine), I click on the link on YT taking me to Adobe, I download and install like lead instructions , but it does not work. Why didn't ActiveX installs as well as the installer of Flash if necessary?

  • Whenever I play youtube videos, they shake from left to right and to go at different speeds.

    I have windows 7. A couple of days, I went to play youtube videos and they all shake from left to right and go at different speeds (very erratic). This ONLY happens with videos from youtube (HTML5). When I play other videos(non-HTML5), they play very well. Also, the sound on youtube videos are fine, only they do not match the mouth (s) of people talking. The mouth move faster. I've checked all my plug-ins and everything is up-to-date. My firefox browser is also the last version. I did a malwarebytes scan and it came up with nothing. All the settings on the youtube videos are also where they should be. It happened for about 5 days. Can someone help me?

    Thanks Guigs. I followed your instructions and found out it was a 'acceleration hardware problem' that was the origin of the problem. I unchecked the box and YouTube videos play very well! Thank you for taking the time to help me.

  • Microsoft have a flash drive, or should I continue to use Adobe flash player, which won't let me access Youtube?

    I run Windows XP and have updated it quite regularly.  Since the September update Adobe Flash Player, I was not able to play Youtube videos.  I can get on YouTube but when I click on a video to my computer crashes.  I tried updates of Adobe since then and they are no better.  Wondered if Microsoft has a flash drive that works.

    Could be a toolbar or an addon that is the cause of the crash. I would like to scan your system with a virus scanner. See if you have malware. If it bluescreens, what say? It shows the name of a file or a driver?

  • V27, 27.1, won't play YouTube videos. Even in safe mode

    I can't watch videos on my default browser, the latest Firefox v 27. I think that I am not alone in this.

    I do not have the latest versions of Flash Player, Real Player, and Javascript is enabled (not java)

    I found it first in the videos of my favorite site of cats (cheezeburger..), but I just find that it comes up with videos of Serif community more. Video accessed via FP work, even when the so-called YouTube (clicked)

    Work live YouTube videos, but not the videos of YouTube accessible via cheezburger links.

    These defects occur only in Firefox 27 and videos play OK in Maxthon 3, (Chrome and Opera - the last time I checked). I know that you do not recommend this but can tell you exactly how to reload the previous version of Firefox, V26 - I had no problem with that.

    I tried to run FF27 in safe mode, no effect. I don't want to lose the different add-ins I use, if I don't want to reset to the factory settings.

    I think is not necessary.

    Click with the mouse right button on the Bookmarks box or in the bar (press F10 or alt to see the title bar) title, and then click Customize

    Then drag the address located above the tabs of stripe bar and.

  • BlackBerry Smartphones can not play youtube video with the 3G network, but works with WiFi, why? Help, please!

    Hello

    I tried several times to read the youtube videos with network wifi and it works fine, but when I use the 3G or GPRS nework to play the video, it first to ask "Switch to WAP for streaming media? (with wifi that he won't ask) so I press ok and it uptempt to load and an error message "content not available. Server is blocked or unresponsive. ", it goes with all the videos I click on that. Help, please.

    Thank you

    Let me share my personal experience on the subject. When they are facing the same problem, I asked my provider and they tried to pull a fast explaining that viewing videos on the 3G network is dependent on the device and that it is not possible to videos on my BB "BOLD" due to speed issues. They even suggested that I buy an iPhone 3G given that subscribers who do not seem to display YouTube videos problems. A load of rubbish! After only a brief workshop organized by RIM and my career, I was "unofficially" informed by a member of staff that it was a TCP/APN issue. I take advice, made the necessary adjustments, and was able to view Youtube videos on the 3 G network without problem. However, my Bill the next month floored me. Even if I'm on a package data unlimited, I was charged an extra $ 70 on top of what I usually pay. Learn more with my carrier, they were kind enough to inform me that I have to access the Internet via their APN address, which translates into a lower speed of AFN, orI will have to pay for accessible data on the other addresses of the AFN. I supported with my questions and my carrier eventually admitted that they were actually limiting the speed on AFN as allowing only some mobile devices to access data at 3G speed. Then you tell me!

  • No built-in play Youtube Video

    I joined Youtube videos in my DPS project, but they will not play. Loading the image of the poster, including a red play button, but when I push button nothing happens. If I press the icon "info" at the top of the Youtube video twice then it reloads and will play the video. Of course it won't work as a solution.

    In addition, it works fine in the preview of the office but once I have test on the iPad, it fails.

    I'm happy to announce that Google has already deployed a fix, and embedded YouTube videos are once again streaming in apps DPS!

  • Recently, when I try to play Youtube videos they start and after about 2 seconds I get ' year error occurred. " "Please try again later".

    I have the latest version of Firefox and also the latest version of the flash player.
    YouTube videos play fine on internet explore and google chrome.

    Thank you for that, but have you seen a difference when using the HTML5 player by turning off Flash?

    There was a change in the default drive that youtube has used this week to other latest browsers and this can affect you.
