Everytime I open a youtube video (embbed or not) I get a black screen and my whole pc crashes. Only happens in firefox, no other browser.

Newest version of firefox, and flash. Tried clearing cache. Been having this problem for a year or more.
No mater what I do, if I open a youtube video in firefox, my pc crashes. Black screen and I have to hit the manual reset button. No error report to send, no idea why this happens. It does not do it when using chrome.
Really irritating and going to cause me to give up on using firefox if I cannot find a solution soon.

You can check for problems with current Flash plugin versions and try these:
*disable a possible RealPlayer Browser Record Plugin extension for Firefox and update the RealPlayer if installed
*disable protected mode in the Flash plugin (Flash 11.3+ on Windows Vista and later)
*disable hardware acceleration in the Flash plugin

Can you check the Windows event log to see if that gives any clues about the Windows crashes if you get a BSOD?

Tried restarting it and; as you might have guessed I'm not very tecky. Anyone out there? Please help me...I'm hopeless. Thanks

I'm experiencing the same problem as described above and it all started after tha 10.8.2 upgrade.
I had no issues until the last upgrade.
Has Apple responded to anyone about a solution to this problem?
I'm running a Mid-2012 MBP-R also.

Why do I get a black screen and no sound when playing video in iTunes 8?

Just downloaded the new iTunes. I don't have any video playback when I click preview in the store. No video when I try to play anything that I've already downloaded. The play cursor moves but I have a black screen with no sound. I'm hoping this is just a temporary glitch.
Any recommendations? I'm using the latest version of Leopard 10.5.4 on an Intel iMac.

Yeah! Problem solved: It's a QT issue.
Cause: Mac Update Software downloaded a faulty QT.
Solution: Download QT from Apple's QT site.
Great to have the Video back

I downloaded the new itunes update and now no videos will play. I get a white screen and no sound. also a bunch of songs i have purchased no longer play.

i have a bunch of files that can't be located and some songs that i purchase that when you click on them they skip to the next song. also all my videos, movies and tv shows i purchased come up with a white screen and no sound they show they are playing

"Add Folder to Library" is still where it always was, in the File menu.
The new "innovation" is that the File menu is hidden by default! But you can reveal it by using CTRL+B.

When I open firefox (note: I got firefox version 28.0 and Karspersky security 2014) I get a black screen, looking like a command prompt window, in firefox.

Hi,
When I open firefox (note: I got firefox version 28.0 and Karspersky security 2014) I get a black screen covering the whole firefox window and it looks more lika a big command prompt window, in firefox. What is it?

Huh, that's a new one...
Can you try Firefox in [[Safe Mode | Safe Mode]] to see if the problem goes away. I'm thinking it's an extension.
*Run ''firefox.exe -safe-mode'' in the search bar on the Start Menu. (Make sure Firefox is closed)
Have you added any new extensions recently around the time this started happening? Your system details shows the following:
*Adobe Acrobat - Create PDF 1.2 ([email protected])
*Anti-Banner 14.0.0.4917 ([email protected])
*Dangerous Websites Blocker 14.0.0.4917 ([email protected])
*Kaspersky URL Advisor 14.0.0.4917 ([email protected])
*Troubleshooter 1.1a ([email protected]) '''This is default so this isn't the problem.'''
* Virtual Keyboard 14.0.0.4917 ([email protected])

When i open a youtube video in firefox it immediately shows that whole video is streamed when it is yet to stream fully

I am using Firefox 3.6.13. When i open a youtube video in firefox it immediately shows that whole video is streamed (the progress bar shows red instead of grey). But the whole video is yet to be streamed. The information of how much is streamed becomes unavailable.
Listing 2 of the problems encountered because of this
1. Unable to estimate how much time I have to wait before the video is fully streamed
2. Cannot go forward or backward in the video in the streamed part.
(This problem does not occur in IE. I tried the link given below)

I think once I did not even see the page in my history

Summarize your question in a sentencewhen i open a youtube videos it doesnt open and it shows the folloing statement"You need to upgrade your Adobe Flash Player to watch this video. Download it from Adobe."

Your above posted list of installed plugins doesn't show the Flash plugin for Firefox.

Can't install open office; youtube videos + green screen; using call HP Tech Support fails

Can't install open office; youtube videos are green screen (audio ok); using call HP Tech Support fails (no reason given)
1) Can't turn McAfee Livesafe off, and think it's what's keeping me from installing Open Office. It downloads but can't install.
2) At work on wireless guest, youtube looks fine. At home on ethernet through DISH satellite, it's green screen. This is not he case with my older HP laptop connected to the same ethernet cable.
3) Why is HP tech support rejecting me, after I type everything in? If I ca't use it, don't make it an option!!!! The forums were choice #2, so here I am ... make me proud ...
Thanks everyone!!!!

An alternative to OpenOffice would be KingsSoft Office, it performs better and still Free:
http://www.kingsoftstore.com/
McAfee products are problematic on some systems and suggest you uninstall it using their removal too then reboot:
http://service.mcafee.com/FAQDocument.aspx?id=TS101331
Build in Windows Defender should reactivate after the reinstall. As an antivirus product it is adequate as long as you practice safe surfing habits.
Windows key + X, select Command Prompt (Admin) and type: sfc /scannow
Let me know if it does not fix all or any corrupt system files.
Reboot and now try your Youtube.
I do not have an answer to what transpired between you and HP Support but only to say you should come here first.
Please mark my post as SOLVED if it has resolved your problem. It helps others with similar situations.

Safari Browser in my iPhone 5S Hangs/Crashes when I was trying to open an Youtube video.Why is this happening?

My iPhone 5S(Boasted as Worlds smartest smartphone) Hangs/Crashes when I was trying to open any Youtube video....
Is there any fix for this apple.......???
I love my iPhone 5s.But I'm pretty dissapointed.
Coz...........
Feeling ashamed of buying a smartphone worth Rs.51,000 which can't play a youtube video in its stock browser.
Its a zippy task that can be done by a mobile worth Rs.5,100........
Its shame on your part Apple..........
Please fix this as soon as possible.
Consider this bug & fix this in iOS 8......

Google's Chrome browser is very well capable of doing what I want with ease....(on my iPhone)
But Apple's Safari browser(much praised) cant move a speck on it...
Why???........Whats wrong with the stock Safari Browser???

YouTube Video's will not load, is there a way to fix this?

I have flash installed and all YouTube video's will not load. In their place there is a black box when I right click on this box it says "movie not loaded..." and "about adobe flash player." All other flash related video's load fine it seems to be a problem only with YouTube. This problem persists into Google Chrome but not Internet Explorer.

This has been reported many times over the past 24 hours and if the solution hasn't been posted yet, one short-term workaround is to change from a regular session to a secure session.
Click in the URL and insert an s after http. In other words:
http://www.youtube.com/ ==> https://www.youtube.com/

I have an active subscription but everytime I open the program it says trial expired. I have installed, reinstalled, and installed again. I have also installed the windows registry patch.

I have an active subscription but everytime I open the program it says trial expired. I have installed, reinstalled, and installed again. I have also installed the windows registry patch.
It wouldn't install for nearly 5 times I tried to do this. Now it's finally installed again but it won't budge past the trial version. I click BUY NOW but then it says "error you already have a subscription" then it times out and just stays on the Trial Expired page.

Hey kushlar,
Please log out from your Adobe application and login again.
Once you launch Acrobat and get error saying trial expired, you will find an option saying 'license this software'.
Select this option and enter your credentials.
Now check and let me know.

Cannot see embedded Youtube videos; I get a black screen

So, embedded Youtube videos suddenly stopped working. I can still watch videos on the Youtube website just fine. Making an embedded video fullscreen also allows me to see it. I have seen an answer on another thread asking to try Safe Mode. Interestingly, disabling every add-on and plugin (besides Flash and Shockwave) does not fix the issue, but using Safe Mode, which theoretically does the same thing, fixes it :S
The embeds are black screen, and when I hover the mouse over them I see the Refresh and HD buttons, but not the Youtube icon on the lower right. Clicking the lower right area still brings me to the Youtube website, so the button still works, just isn't visible. Reinstalling Waterfox and using a new profile do not fix the issue.
I can't test the issue on Firefox because it has a long-standing problem of the Flash Player crashing constantly every second, which rendered it unusable and is the reason I switched to Waterfox in the first place (in which Flash does not crash).
The troubleshoot information with all Waterfox add-ons disabled (which again, doesn't fix the issue, despite Safe Mode fixing it) can be seen by navigating to the "More system details" on the menu to the right.
Thanks!

I had disabled hardware accel in Waterfox and it didn't fix the embeds, but doing so in Firefox fixed them for Waterfox! Odd. It didn't fix the constant Flash Player crashing, though. Thanks for solving the embeds!

Everytime I open a youtube video (embbed or not) I get a black screen and my whole pc crashes. Only happens in firefox, no other browser.
