Safari 7.0 won't play YouTube videos correctly.

Since upgrading to Mavericks and Safari 7.0, YouTube videos will only play for a few seconds before stopping. There is no audio, and if I click play nothing will happen, however by scrubbing forward or backwards it will continue to play for a few more seconds before stopping again. I have emptied my cookies to no avail.

Open System Preferences > Flash Player then select the Advanced tab.
Click Delete All under Browsing Data and Settings
Not empty the Safari cache.
From your Safari menu bar click Safari > Preferences then select the Advanced tab.
Select: Show Develop menu in menu bar
Now click Develop from the menu bar. From the drop down menu click Empty Caches.
Now try a video.

I have windows 8.1 and firefox won't play youtube videos but IE will

I have windows 8.1 and firefox won't play youtube videos but IE will. I have tried reinstalling firefox, flash, java. Resetting firefox don't help, disabled hardware acceleration, protected mode 0 in the mms.cfg file. Nothing will play on youtube in firefox. It says "an error has occured, please try again later". The ads play fine though. Everything plays fine in IE. I have tried different versions of flash also with no luck. I even restored the system to a previous iso image with no luck. Does anyone have a solution?

It maybe because your javascript is disabled .
You can check the javascript.enabled pref on the about:config page.
http://kb.mozillazine.org/about:config
There are also extensions that can block JavaScript or otherwise interfere.

Or,
"Clear the Cache":
Firefox > Preferences > Advanced > Network > Cached Web Content: "Clear Now"
"Remove Cookies" from sites causing problems:
Firefox > Preferences > Privacy > Cookies: "Show Cookies"
Start Firefox in [https://support.mozilla.org/en-US/kb/troubleshoot-firefox-issues-using-safe-mode Safe Mode] to check if one of the extensions (Firefox/Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.

Safari won't play youtube videos anymore. I've never had trouble in the past. I switched to chrome but then back to safari and changed the default browser to safari. Now safari won't open any sites that require a user and password. Any suggestions?

Hello everyone,
I've recently been getting error messages on youtube videos when using safari. This never used to happen. I tried using chrome but it didn't take care of the problem. When I set my default browser back to safari, safari won't open any websites that require a username and password. Any suggestions?

My case is different from those listed below. First, I'm running OS X 10.8.5 and Safari 6.0.5.
My problem is this:
I run a Google search, say, "youtube somesong", and from the hit list returned from google I
pick some selection. Youtube launches and plays the video without problems. However, when
i click on any of the alternate videos from the page's vertical list, only the name of the chosen video
appears beneath the video I just watched. The new selection itself is not loaded by Safari.
This occurs for any selection I choose. My way around this problem is to force a Safari reload of
the page by using the keyboard shortcut, Command-R. This fills in the old video window with the
video I just chose. Can I conclude that this is a Safari issue alone, or is it a Safari/Youtube combo gotcha? Anyway, the present condition *****.
This problem began sometime after i upgraded to Mountain Lion. I have reset Safari and have also
deleted the Youtube.com Cache, Cookies, and Local Storage from the Privacy settings under
System Preferences. I have also tested the problem by running Safari in 32 bit mode (no luck there).
If anyone out there has experienced this scenario, I sure could use a little help here.

Facebook won't play youtube video's on my macbook pro, it says that i need to upgrade adobe flash. But on Safari, youtube plays perfect.........i need some answers

But when i watch youtube videos on safari it plays perfectly fine. Is there a problem with facebook concerning adobe flash?.................please help.......i need some answers!!!

No.
Software Update is for Apple software. Adobe is 3rd party.

Firefox won't play Youtube videos or media videos

It is 2 am and for almost a month now Firefox has slowly been degrading to the point of being completely and utterly useless. First, vine videos went. Then the weather.com videos stopped working. Every video based website online has stopped working right up to youtube finally cracking out today.
Videos won't play. I run firefox in safe mode and STILL, videos show up as a black screen. I tried turning off 'hardware acceleration' in flash, still nothing. I tried clearing the cache, history, deleting firefox altogether and reinstalling.
I'm running Windows Vista. Using Chrome, every video based site runs impeccably so it is definitely a Firefox conflict. I should probably just stop using firefox altogether, but I've been running it for years and it's what I'm used to. I'm getting down right sick of this though.
Things I have tried:
-Running in safe mode: Nothing
-Clearing the cache/history: Nothing
-Disabling add-ons one by one: Nothing
-Disabling hardware acceleration on Flash: Nothing
I don't know what else to do anymore.

Update your Flash player. It is currently blocked because you have a vulnerable/blocked version installed.

Palm treo pro t850 won't play youtube videos

im using my home wifi connection to go online with my treo pro. it loads everything perfectly except SOME youtube videos. and it only happens when i am running as a mobile device. when i run as a desktop device everything loads. any ideas to what could cause this?

Try Safari and Lion forums, then bookmark the actual MacBook Pro forum.
And maybe a url if you want it to be cecked. And try Chrome. Try Firefox. And make sure your plugins and extensiions work. Safari was updated and there were security updates. And only install from Adobe such as
http://getflash.com or www.adobe.com and downloads.

Mac 10.6 Safari or Chrome, unable to play Youtube videos, error message pops up

Youtube vids load but will not play. Have changed all the speed settings etc, on cabel and checked speed and that's not an issue. Vimeo and others will play consistley but nothing on youtube. Get error message that says"unable to play video, please try again". I know someone has the solution to this. Thank-you in advance.

This is quite long but bear it out. Re: Antivirus on a Mac.
1. This comment applies to malicious software ("malware") that's installed unwittingly by the victim of a network attack. It does not apply to software, such as keystroke loggers, that may be installed deliberately by an intruder who has hands-on access to the victim's computer. That threat is in a different category, and there's no easy way to defend against it. If you have reason to suspect that you're the target of such an attack, you need expert help.
If you find this comment too long or too technical, read only sections 5, 6, and 10.
OS X now implements three layers of built-in protection specifically against malware, not counting runtime protections such as execute disable, sandboxing, system library randomization, and address space layout randomization that may also guard against other kinds of exploits.
2. All versions of OS X since 10.6.7 have been able to detect known Mac malware in downloaded files, and to block insecure web plugins. This feature is transparent to the user, but internally Apple calls it "XProtect." The malware recognition database is automatically checked for updates once a day; however, you shouldn't rely on it, because the attackers are always at least a day ahead of the defenders.
The following caveats apply to XProtect:
It can be bypassed by some third-party networking software, such as BitTorrent clients and Java applets.
It only applies to software downloaded from the network. Software installed from a CD or other media is not checked.
3. Starting with OS X 10.7.5, there has been a second layer of built-in malware protection, designated "Gatekeeper" by Apple. By default, applications and Installer packages downloaded from the network will only run if they're digitally signed by a developer with a certificate issued by Apple. Software certified in this way hasn't necessarily been tested by Apple, but you can be reasonably sure that it hasn't been modified by anyone other than the developer. His identity is known to Apple, so he could be held legally responsible if he distributed malware. That may not mean much if the developer lives in a country with a weak legal system (see below.)
Gatekeeper doesn't depend on a database of known malware. It has, however, the same limitations as XProtect, and in addition the following:
It can easily be disabled or overridden by the user.
A malware attacker could get control of a code-signing certificate under false pretenses, or could simply ignore the consequences of distributing codesigned malware.
An App Store developer could find a way to bypass Apple's oversight, or the oversight could fail due to human error.
For the reasons given above, App Store products, and other applications recognized by Gatekeeper as signed, are safer than others, but they can't be considered absolutely safe. "Sandboxed" applications may prompt for access to private data, such as your contacts, or for access to the network. Think before granting that access. OS X security is based on user input. Never click through any request for authorization without thinking.
4. Starting with OS X 10.8.3, a third layer of protection has been added: a "Malware Removal Tool" (MRT). MRT runs automatically in the background when you update the OS. It checks for, and removes, malware that may have evaded the other protections via a Java exploit (see below.) MRT also runs when you install or update the Apple-supplied Java runtime (but not the Oracle runtime.) Like XProtect, MRT is presumably effective against known attacks, but maybe not against unknown attacks. It notifies you if it finds malware, but otherwise there's no user interface to MRT.
5. XProtect, Gatekeeper, and MRT reduce the risk of malware attack, but they're not absolute protection. The first and best line of defense is always your own intelligence. With the possible exception of Java exploits, all known malware circulating on the Internet that affects a fully-updated installation of OS X 10.6 or later takes the form of so-called "trojan horses," which can only have an effect if the victim is duped into running them. The threat therefore amounts to a battle of wits between you and the malware attacker. If you're smarter than he thinks you are, you'll win.
That means, in practice, that you never use software that comes from an untrustworthy source, or that does something inherently untrustworthy. How do you know what is trustworthy?
Any website that prompts you to install a “codec,” “plug-in,” "player," "extractor," or “certificate” that comes from that same site, or an unknown one, is untrustworthy.
A web operator who tells you that you have a “virus,” or that anything else is wrong with your computer, or that you have won a prize in a contest you never entered, is trying to commit a crime with you as the victim. (Some reputable websites did legitimately warn visitors who were infected with the "DNSChanger" malware. That exception to this rule no longer applies.)
Pirated copies or "cracks" of commercial software, no matter where they come from, are unsafe.
Software of any kind downloaded from a BitTorrent or from a Usenet binary newsgroup is unsafe.
Software that purports to help you do something that's illegal or that infringes copyright, such as saving streamed audio or video for reuse without permission, is unsafe. All YouTube "downloaders" are in this category, though not all are necessarily harmful.
Software with a corporate brand, such as Adobe Flash Player, must be downloaded directly from the developer’s website. If it comes from any other source, it's unsafe.
Even signed applications, no matter what the source, should not be trusted if they do something unexpected, such as asking for permission to access your contacts, your location, or the Internet for no obvious reason.
6. Java on the Web (not to be confused with JavaScript, to which it's not related, despite the similarity of the names) is a weak point in the security of any system. Java is, among other things, a platform for running complex applications in a web page, on the client. That was always a bad idea, and Java's developers have proven themselves incapable of implementing it without also creating a portal for malware to enter. Past Java exploits are the closest thing there has ever been to a Windows-style virus affecting OS X. Merely loading a page with malicious Java content could be harmful.
Fortunately, client-side Java on the Web is obsolete and mostly extinct. Only a few outmoded sites still use it. Try to hasten the process of extinction by avoiding those sites, if you have a choice. Forget about playing games or other non-essential uses of Java.
Java is not included in OS X 10.7 and later. Discrete Java installers are distributed by Apple and by Oracle (the developer of Java.) Don't use either one unless you need it. Most people don't. If Java is installed, disable it — not JavaScript — in your browsers.
Regardless of version, experience has shown that Java on the Web can't be trusted. If you must use a Java applet for a task on a specific site, enable Java only for that site in Safari. Never enable Java for a public website that carries third-party advertising. Use it only on well-known, login-protected, secure websites without ads. In Safari 6 or later, you'll see a lock icon in the address bar with the abbreviation "https" when visiting a secure site.
Follow the above guidelines, and you’ll be as safe from malware as you can practically be. The rest of this comment concerns what you should not do to protect yourself from malware.
7. Never install any commercial "anti-virus" or "Internet security" products for the Mac, as they all do more harm than good, if they do any good at all. Any database of known threats is always going to be out of date. Most of the danger is from unknown threats. If you need to be able to detect Windows malware in your files, use one of the free anti-virus products in the Mac App Store — nothing else.
Why shouldn't you use commercial "anti-virus" products?
Their design is predicated on the nonexistent threat that malware may be injected at any time, anywhere in the file system. Malware is downloaded from the network; it doesn't materialize from nowhere.
In order to meet that nonexistent threat, the software modifies or duplicates low-level functions of the operating system, which is a waste of resources and a common cause of instability, bugs, and poor performance.
By modifying the operating system, the software itself may create weaknesses that could be exploited by malware attackers.
8. An anti-malware product from the App Store, such as "ClamXav," doesn't have these drawbacks. That doesn't mean it's entirely safe. It may report email messages that have "phishing" links in the body, or Windows malware in attachments, as infected files, and offer to delete or move them. Doing so will corrupt the Mail database. The messages should be deleted from within the Mail application.
An anti-virus app is not needed, and should not be relied upon, for protection against OS X malware. It's useful only for detecting Windows malware. Windows malware can't harm you directly (unless, of course, you use Windows.) Just don't pass it on to anyone else.
A Windows malware attachment in email is usually easy to recognize. The file name will often be targeted at people who aren't very bright; for example:
♥♥♥♥♥♥♥♥♥♥♥♥♥♥!!!!!!!H0TBABEZ4U!!!!!!!.AVI♥♥♥♥♥♥♥♥♥♥♥♥♥♥.exe
Anti-virus software may be able to tell you which particular virus or trojan it is, but do you care? In practice, there's seldom a reason to use the software unless a network administrator requires you to do it.
The ClamXav developer won't try to "upsell" you to a paid version of the product. Other developers may do that. Don't be upsold. For one thing, you should not pay to protect Windows users from the consequences of their choice of computing platform. For another, a paid upgrade from a free app will probably have the disadvantages mentioned in section 7.
9. It seems to be a common belief that the built-in Application Firewall acts as a barrier to infection, or prevents malware from functioning. It does neither. It blocks inbound connections to certain network services you're running, such as file sharing. It's disabled by default and you should leave it that way if you're behind a router on a private home or office network. Activate it only when you're on an untrusted network, for instance a public Wi-Fi hotspot, where you don't want to provide services. Disable any services you don't use in the Sharing preference pane. All are disabled by default.
10. As a Mac user you don't have to live in fear that your computer is going to be infected every time you install an application, read email, or visit a web page. But neither should you have the false idea that you will always be safe, no matter what you do. The greatest harm done by security software is precisely its selling point: it makes people feel safe. They may then feel safe enough to take risks from which the software doesn't protect them. Nothing can lessen the need for safe computing practices.

My macbook pro still won't play youtube videos even after i installed adobe flash play. What do I do?

I updated to the newest version of FIREFOX and now my NETFLIX won't play, YOUTUBE videos will not play. I was one of the people that donated to you this year.

Hello Mozilla/FIREFOX I just updated to your latest version and now my NETFLIX nor my YOUTUBE plays anymore. I just get a black space without any volume or play symbols - this isn't working for me. I donated to your organization as I am a supporter but you'll need to honor your side of the street. What are you guys doing to fix this and by when will it be resolved?

Hello,
The Refresh feature (called "Reset" in older Firefox versions) can fix many issues by restoring Firefox to its factory default state while saving your bookmarks, history, passwords, cookies, and other essential information.
'''''Note:''' When you use this feature, you will lose any extensions, toolbar customizations, and some preferences.'' See the [[Refresh Firefox - reset add-ons and settings]] article for more information.
To Refresh Firefox:
# Open the Troubleshooting Information page using one of these methods:
#*Click the menu button [[Image:New Fx Menu]], click help [[Image:Help-29]] and select ''Troubleshooting Information''. A new tab containing your troubleshooting information should open.
#*If you're unable to access the Help menu, type '''about:support''' in your address bar to bring up the Troubleshooting Information page.
#At the top right corner of the page, you should see a button that says "Refresh Firefox" ("Reset Firefox" in older Firefox versions). Click on it.
#Firefox will close. After the refresh process is completed, Firefox will show a window with the information that is imported.
#Click Finish and Firefox will reopen.
Did this fix the problem? Please report back to us!
Thank you.

Safari won't play certain videos

Hi there,
it came to my attention that my Safari (latest version) won't play any video on the site "www.collegehumor.com". YouTube and every other popular site works fine for me. After googling this problem, I tried to play the videos with a different user; without success. After that, I uninstalled the Flash Player and reinstalled it (latest version), because this was suggested by my google searches... but I still can't play any video on collegehumor.com.
Has anyone any idea what the problem might be?
thanks in advance!

Safari 3.2.1 Won't Play Youtube

I can't seem to get Safari 3.2.1 to play Youtube videos. The entire page seems to load up OK just that the video part does not load.
I've performed the following to no luck:-
1.) Re-installed 3.2.1
2.) Re-installed Adobe Flash
3.) Full reset of Safari
Take a look at the screenshot to give you a better idea as to what I'm facing.
http://public.capkapak.fastmail.fm/Picture%201.png
Anyone with any ideas?

I just checked the URL on the YouTube page in your photo, and it worked fine for me - although I am not a great fan of butternut squash!
So, we should be able to get it to work for you as well.
When you say you reinstalled Flash, which version? I use version 10.
It might be worth uninstalling, then reinstalling FlashPlayer again:
The latest version of Adobe FlashPlayer can be obtained from here:
http://www.adobe.com/shockwave/download/download.cgi?P1ProdVersion=ShockwaveFlash
(You can check here: http://www.adobe.com/products/flash/about/ to see which version you should install for your Mac and OS.
Note that Adobe requires you to uninstall any previous version of Flash Player, using the uninstaller from here (make sure you use the correct one!):
http://kb.adobe.com/selfservice/viewContent.do?externalId=tn_14157
and also that you follow the instructions closely, such as closing ALL applications first before installing. You must also carry out a permission repair after installing anything from Adobe.

Why won't my macbook pro play youtube videos?

Why wont my macbook pro play youtube videos????
I bought this over the summer and it's now Nov 28th. I've had it with this thing and nobody is answering my question! Please help!
I reset safari, emptied my cache, cleared my history, uninstalled and re-installed flash player and nothing has helped. In fact, un/reinstalling flash player worsened the problem. And I cannot update it becuase it says "not recognized".
I do have avast anti-virus: but I can't fix the warnings in it (after I scan, some warnings popup and it wont let me fix it and I have no idea where to find it in the computer itself). Does this have anything to do with it? I need virus protection, so I dont want to get rid of it.
I do not have the money to buy firefox (and it's never worked for me ever anyways).
I know it's not my internet because my dad's pc works great and my sister's mac (for school) loads youtube videos instantly.
I also have this annoying issue where every page on the interned needs to be reloaded three times before itll load the first time. It sits there for five minutes and does nothing, then I reload the page and BAM its loaded: EXCEPT YOUTUBE.
For a $1400 machine, I'd like to know what and why this is happening.

Perhaps there is something wrong with your software and/or a corrupt cache file outside of the browser.

Hmm hard to tell what's causing this. May have to do a process of elimination to cure everything on the machine.

Uninstall the anti-virus, they always cause issues on Mac's.
You say you need anti-virus, so install the free ClamXav, it's a program you run as you need it, because 99% of the malware out there is for Windows and won't run on a Mac, thus you can just run ClamXav when you need it on where you need it. Won't bugger up the machine.
I do not have the money to buy firefox (and it's never worked for me ever anyways).
Firefox is a free web browser by the open source community, it's very powerful and highly customizable with more add-ons, extensions, personas, themes than any other browser. Some things can be done on Firefox can't be done on any other browser at all. Certainly for someone who is a bit more seasoned to use it fully.

You mentioned your "dad" and you've mentioned a delay loading pages and not YouTube at all.
Are you by any chance the Administrator of the computer? Can you install Firefox if you wanted too just as a experiment or does it ask for a Admin name and password and you can't provide it?
"Nannyware" has the ability to block sites and slow down page draws as it's consulting with the nannyware company if that site is suitable to be loaded on your machine.
If your are the Admin of the machine, then your going to have to methodically go through the fix it list I've generated here to resolve your issue as I cant' tell what's causing your problem specifically behind a screen.
If it's too much for you, take the machine to a local Mac/PC software repair shop and they can fix you up.
I suspect by #12 your machine will be fixed.
