Black screen Youtube videos

I just started getting this black screen instead of some youtube videos whilst they are running , and whilst the sound still goes on perfectly fine. It's rare that it happens and it can change into the normal image, and when i change from full screen view to normal view it can also change back to the normal/real image. Does anyone know what that could be from?

It showed up on another video site besides youtube as well. It is like these lapses of flash... memory (or something) that make these small spaces of the videos blackened out. (Sometimes the whole video?) Restarting Firefox seems to fix it. Cleaning the cache doesn't fix it. Refreshing the video/page doesn't ?

I've not installed any new addons, i did update flash recently.

Start with this;

Tyler Downer has replied to a thread you're watching. Here is their reply: Hey all, Just an update. A 0day exploit has been discovered in Flash, and below. Adobe has released an update to which fixes this issue. All users should update to the latest flash immediately. It isn't known how far back this hold exists, but at this time assume all versions are affected.

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

  • see if there are updates for your graphics drive drivers

  • disable protected mode in the Flash plugin (Flash 11.3+ on Windows Vista and later)

  • disable hardware acceleration in the Flash plugin See also:

I think what happened with flash was that flash asked for an update, and it didnt download it through a browser, it just autoupdated itself. Not sure if that's relevant?

more options

I thought i have the latest flash now, what should i be doing?

more options

Also another thing that started happening a bit prior to this is when i click on google tabs they give me an instant ssl error? or something and the page doesn't load until i refresh it

more options

I guess i uninstalled flash and then i uninstalled adobe shockwave player and now i installed the latest versions. Adobe AIR is the only one that i haven't updated

Are you still having issues?

more options

Yes ,it still happens sometimes , although seemingly not as often as it used to. Or maybe it's because of the newest flash update. (i did update right when it came out two days ago)

more options

It seemed like it worked for a while ,but now what happens is sometimes , i'd say 1 out of 6-7 times i go to full screen in youtube videos , that flash screen hangs and makes firefox hang with it , and i have to end the process ,and sometimes i have to do it to firefox as well

more options

I noticed that opening 5-6 youtube videos will make the black screen permanent across the entire youtube video And refreshing the video won't help at all ,the entire video will just stay black

But if i close 2-3 youtube videos, now it appears normally

I've called the big guys to help you. Good luck.

Thank you Fred.

It's sort of irregular, so it took me a while to make sure it was still happening after i reinstalled flash.

Can you please provide the new troubleshooting information from after updating your graphics card from about:support.

There is an new feature in the about:config page that disables protected mode in the flash plugin player. Try disabling graphics hardware acceleration. Then perform these steps:

  1. Open Firefox Options window (Preferences on Mac or Linux) as follows:
    • In Firefox 29.0 and above, click the menu button New Fx Menu and select Options for Windows or Preferences on Mac or Linux.
    • In Firefox 28.0 and previous versions, click the orange Firefox button at the top left, then select the "Options" button, or, if there is no Firefox button at the top, go to Tools > Options.
  2. In the Firefox Options (or Preferences) window, click the Advanced tab, then select General.
  3. In the settings list, you should find the Use hardware acceleration when available checkbox. Uncheck this checkbox.
  4. Now, restart Firefox and see if the problems persist.

Currently I do also know that they are still investigating. It is recommended to change the plugin to "ask to activate" while they continue to make improvements to the security issues.

Yes, sir , My Hardware acceleration is unchecked

Maybe is a a good idea to reset all prefs by deleting the prefs.js file in the Firefox profile folder to cleanup the prefs because your troubleshooting information shows preferences from older Firefox versions that are no longer supported in the current releases.

Well pretty much all the addons are old, and the problem is relatively new. The antivir addons for avast were definitely somewhat problematic, but the only thing i could do was to disable them ,so that's their status since then
