youtube videos won't play

FireFox v13.0.1 installed on Win 7/64 system.

Adobe Flash and Shockwave installed yesterday.

Whenever I try to view a Youtube video, I select it and the screen with the arrow appears. When I click on the start arrow, the screen goes black and a warning on the screen appears:

An error occurred. Please try again later.

On the same machine, YouTube videos play fine on IE v9 and Google Chrome v19.0.1084.56 m.

Suggestions, or is this goodbye to FireFox?

Thanks

Re: youtube videos won't play

Sorry but Firefox seems still to have problems with FlashPlayer 11.3 on Windows.

Please for now try uninstalling FlashPlayer 11.3 and downgrading to FlashPlayer 11.2 or 10.3. (Also note there may be a separate issue if used with RealPlayer). Developers from Firefox and Flash have been trying for a few days to get reliable fixes to these issues,

See for instance the latest revision of


Update.

Although not as straightforward as sticking with Flash10.3 a better option now ( Especially as security patches have been released for FlashPlayer. ) may be to use whatever the current version of FlashPlayer is but try with Adobe FlashPlayer's protected mode disabled. Full instructions on how to do that may be found in the article

You may find that the Mozillazine articles are more up-to-date than official Mozilla Firefox KB articles, are likely to go into finer detail, do not shy away from giving alternative and sometimes more complex solutions

Re: youtube videos won't play

I find that the problem only occurs on my (new) laptop which runs Windows 7. On my (old) Windows XP PC I can watch Flash videos in Firefox without any trouble. I tried uninstalling Flash 11 from the laptop and replacing it with 10, but it made no difference. Flash is fine on the laptop in Chrome and IE9, but I'd rather use Firefox!

Re: youtube videos won't play

This issue does not affect IE or Chrome. And it does not affect Windows XP as that is unable to use protected mode (that is a security enhancement that is proving problematic)

Have a look at the general information in case you have a different problem

if you continue to have problems please start your own thread by asking a question

  1. use link [/questions/new]
  2. follow the links and prompts that you get
  3. when prompted please please follow the instructions that tell you to copy the troubleshooting information.

Re: youtube videos won't play

Note if you have RealPlayer and want to keep using it there may be workarounds,and RealPlayer developers may well be working on fixes. Other forum posts may offer suggestions, and the KB article has recently been updated:

If you are using Flash 11.3 on Firefox Windows >=Vista, Windows 7 note that there are currently known issues and that some users are finding it necessary to downgrade from FlashPlayer 11.3 as explained previously.
In such circumstances it may be necessary to ignore the advice from the pluginchecker.

Re: youtube videos won't play

<This is not a FlashPlayer issue. It's a RealPlayer Plugin issue> Follow these steps if you get this message on Youtube "an error has occured-please try again later" and John99's solution doesn't work for you : 1) Disable all RealPlayer Plugins or Extensions on FireFox then close Firefox. 2) Launch RealPlayer and click on the RealPlayer icon at the top left. 3) Click Preferences 4) In the Category panel click Download and Recording. 5) Uncheck (remove check mark) from Web Download and Recording and click OK. NOTE: By disabling this you will not be able to download the Youtube video to your computer since the download uses the Realplayer Web download. You can use free software (FREE YOUTUBE DOWNLOAD) by DVDVideoSoft Free Studio at "www.dvdvideosoft.com" to download a Youtube video to your computer if desired. The video will be downloaded into your Video Libraries folder. 6) Start Firefox and try to play the Youtube videos.

This worked for me. I hope it works for you !

Re: youtube videos won't play

There are multiple possible problems, if anyone has a problem with YouTube videos and reading the information in this and other threads,or the linked articles does not help please start your own thread by asking a question.

Please note some of these issues may relate to RealPlayer or Flash 11.3 use and relevant developers are working on the problems.

(A new RealPlayer release has been made recently but is or will be blocklisted by Firefox, possibly this time as a Hardblock that will not be easily re-enabled)

Thanks blacksabbath71! This solved my problem. Now I can play videos again.

Re: youtube videos won't play

You're welcome mazberry ! Glad to have helped you. In following my instructions you will still be able to play videos in the Realplayer library if you have any in it using Realplayer as well as play videos from Youtube and other websites while using Firefox .You will not be able to download a Youtube video to your computer since the Youtube download uses the Realplayer Web download which you disabled to resolve the issue you had. You can use free software (FREE YOUTUBE DOWNLOAD) by DVDVideoSoft Free Studio at "www.dvdvideosoft.com" to download a Youtube video to your computer if desired. The video will be downloaded into your Video Libraries folder. If you uninstall Realplayer, you'll resolve the Firefox issue but you'll no longer have Realplayer. My instructions that you followed gives you the best of both worlds.
