I cannot view any videos on youtube or embedded videos on other sites..

I have upgraded to Firefox 13.0 and double checked all of my plug-ins and addons too. I just went through upgrading everything. I go to the websites to make sure they are working by playing a trailer or a video and they seem to be functioning on that site. When I go to Youtube though and push play it tells me "An error has occurred. Please try again later." I have even tried to uncheck the "Enable hardware acceleration" box too. Nothing seems to be working. Even going back to an earlier version of Firefox does not work or starting in Safe Mode. I can watch videos in IE though just fine, just not in Firefox.

I also updated my Shockwave Flash too but today I was finally able to fix my problem by using the information I found on here:

Thank you!

I loaded 4.0 and now I cannot view any videos. Flash player causes Firefox to stop responding.

I am running XP. I recently loaded Firefox 4.0 on my system.
There were a lot of problems loading some web sites. Your help system suggested to disable all plugins. I did this and I don't have problems with web sites anymore but I cannot view any videos. I have tried reinstalling Adobe Flash but it just causes Firefox to stop responding.
Ideas?

'''''[https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode Start Firefox in Safe Mode]''''' {web link}
While you are in safe mode;
Press the '''<Alt>''' or '''<F10>''' key to bring up the tool bar.
Followed by;
Windows; '''Tools > Options'''
Linux; '''Edit > Preferences'''
Mac; ''application name'' '''> Preferences'''
Then '''Advanced > General.'''
Look for and turn off '''Use Hardware Acceleration'''.
Poke around safe web sites and see if there is still a problem. Then restart

Cannot view any Videos on Youtube after installing flash 10

Hi there.
I had my day off today and have been viewing videos on youtube all day.   I had adobe pop up to say that I should upgrade to the newer flash version and I did this. Afterwards I went back to youtube to continue watching the videos and now I get an error message "An error occurred, please try again later."
I have followed all the advice I could find.   I uninstalled all adobe programs and rebooted the comp then installed again and I still get the same thing.   I downloaded the offline uninstaller and ran it 5 or 6 times then reboot and installed and again same thing.
I am using Vista and I have never had any problems with viewing videos.   I use Firefox as my browser, but Internet Explorer is experiencing the same difficulty for me when I checked it.
Please help me out.   Tried to figure it out on my own but I'm stuck.
Thanks!

Sounds like the problem I was having. Places like YouTube kept asking to upgrade to a new version (which I did) and to check that I had Javascript enabled (which it was). I tried installing new versions of FlashPlayer on several occasions and they seemed to work, but FlashPlayer 10 was clearly not working.
I found a support page http://kb2.adobe.com/cps/494/cpsid_49419.html that directed me to use the standalone uninstaller, then use a Microsoft SubInAcl Registry tool to fix some pemissions in the registry. Then I installed a new version of FlashPlayer and everthing has been working well since. I have no idea hour the registry permissions got messed up in the first place.

Every time I install Flash Player 14 and open my browser I get the message asking me to allow Adobe Flashruntime. I allow it and the message repeats itself constantly. My OS is WIN7 64 bit. My browser is IE11. I cannot view any videos

I would appreciate any assistance with this matter.

I resolved the problem by doing an uninstall and reinstall of IE11. I guess that was the problem all along. Got to love IE.

HT1199 cannot view any video. the words (BLOCKED POP UP appears

I am Not at all computer savy, so it must stay basic

When you have installed the latest version of Flash, relaunch Safari and test.
1. If you're getting a "blocked plug-in" error, then from the menu bar select
 ▹ System Preferences… ▹ Flash Player ▹ Advanced
and click Check Now. Quit and relaunch your browser.

I cannot watch any videos that require adobe flash player. I have tried to download their latest version but nothing happens. Any ideas? I can no longer even view my facebook videos.

I cannot view any video clips requiring adobe flash player such as my facebook videos. When I download the adobe flash player nothing happens and it continually says to download. Any ideas on what I am doing wrong? I am using MacBook Pro O SX. Thank you.

Just to check, in the directory /Library/Internet Plug-Ins do you see the file Flash Player.plugin?
And after reading your last post I have to ask, did you install the plugin after you downloaded it? Of course anwering my first question will answer this question.

After upgrading to mountain lion, i cannot play any video at all, be it directly off a DVD, or through streaming like youtube, BBC iplayer or even off my iTunes library

after upgrading to mountain lion, i cannot play any video at all, be it directly off a DVD, or through streaming like youtube, BBC iplayer, love film or even directly off my iTunes library. in each case, all i get is a black screen and no error message.

Hi, i had the same problem and tried this,
Somehow iTunes is tied to Safari. Try this:
Someone mentioned to clear all website data and history in safari, stupid but it was either this or the below that fixed it
or this,
Disable Wi-Fi Networking Services
Many users have reported that they’ve solved their issues by disabling Wi-Fi Networking under Settings > Privacy > Location Services > System Services. This only relates to your location being used for Wi-Fi Networking, so it doesn’t disable Wi-Fi entirely.
Please let me know if it works.

Cannot play any video (even youtube vids) on my HP TouchSmart 520 with Windows 8 in Metro Mode.

HP TouchSmart 520 PC
Windows 8
Just upgraded from Windows 7 to Windows 8.
Upgrade was uneventful.. went very smoothly.
Problem is now I cannot play any videos in the new Metro Mode (I tried using various apps... Video, youtube player, etc).. not even youtube videos.
However, when I select Desktop mode.. everything still works fine.
Any idea what is wrong ?

Hello WongKO:
Welcome to HP's forum. I do not know much about Windows 8. Reading this fact sheet it says that you need to purchase the media software and upgrade to Windows 8 pro. This fact sheet should guide you. http://www.windowsupgradeoffer.com/en-US/Home/Faq? Windows 8 system requirements section.Will DVD playback work after upgrading to Windows 8? This one is in general section. Will installation media be available for purchase? Back to Windows 8 requirements. Is Windows Media Center included in the upgrade to Windows 8 Pro? Least you are able to watch videos in other mode until you figure out what is best. Good luck frrw. Ounce you have figured out the software purchases you should post it to help others out. My computer is to old for upgrade. No drivers were made for it.

Cannot watch any videos from Youtube

I bought a EA3500 router and the setup went fine. I have two computers on the network and both have acces to the Internet. But on one of them which runs Windows 7 and MCAfee Antivirus I cannot watch any videos from Youtube. On the other one which runs Windows XP all videos are running great. I've check the firmware version and it is the last one. I've try to disable the firewall in McAfee and it still does not work. Can someone help me. Thank you Artofmontreal

Are you still on the classic firmware or are you using cisco connect cloud? It might have something to do with the media prioritization. As long as you did not prioritize a certain device or computer over another, the router should allow all devices to stream.

All of a sudden I cannot watch any videos using Firefox, not even from YouTube. Why?

All of a sudden I cannot watch any videos using Firefox. All I get is a square black box. I can see them if I use Safari. Why isn't my Firefox working? What can I do? Thanks.

Try clearing the Cache in Firefox.
Tools-> Clear Recent History -> [v] Cache
or Firefox->Preferences->Advanced->Network -> Offline storage -> [Clear Now]
Try clearing the Youtube cookie in Firefox->Preferences->Privacy
refresh page.
If that still does not work then try making the youtube url as http'''s'''://
It is apparently a issue with Youtube as people with other browsers are getting the same. http://www.google.com/support/forum/p/youtube/thread?hl=en&tid=3cda4dac122b8f13

I am unable to view any videos on Youtube, my flash player is up to date.

This morning it was fine, now I am not able to view any video's on Youtube, I followed the information on your blog under the flash player options and it did not work.

Try clearing the Cache in Firefox.

Youtube may have made some changes recently. Clear the Youtube cookie and refresh page if above does not do it.

I cannot play any video from Fox website

I cannot play any video off Fox.com with FF. I have updated adobe flash as your blog recommended; still will not play any video. Please help! Thanks,

Your '''''More System Details''''' doesn't show Adobe Flash as being installed! Did you install the Plugin version of Flash? Or did you just update the ActiveX version of Flash which is used only by Internet Explorer?

Cannot play any videos I need helpmplease.

My system is: Windows 64-bit , English, MSIE and have now successfully installed Adobe Flash Player update 17 but I cannot play any videos, news sites or Utube etc. can someone help me fix this please.

First, confirm that ActiveX Filtering is configured to allow Flash content:
https://forums.adobe.com/thread/867968
Internet Explorer 11 introduces a number of changes both to how the browser identifies itself to remote web servers, and to how it processes JavaScript intended to target behaviors specific to Internet Explorer. Unfortunately, this means that content on some sites will be broken until the content provider changes their site to conform to the new development approach required by modern versions of IE.
You can try to work around these issues by using Compatibility View:

If that is too inconvenient, using Google Chrome may be a preferable alternative.
