I can NOT watch youtube in Firefox, WHY??

Opening a video from Youtube in firefox does not work. It works fine in Internet Explorer.

You have the Flash plugin installed according to your More system details list, so [[Flash]] should be working.
Start Firefox in [[Safe Mode]] to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
* Don't make any changes on the Safe mode start window.
See:
* [[Troubleshooting extensions and themes]]
* [[Troubleshooting plugins]]
If it does work in Safe-mode then disable all extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
* Use "Disable all add-ons" on the [[Safe mode]] start window to disable all extensions.
* Close and restart Firefox after each change via "File > Exit" (Mac: "Firefox > Quit"; Linux: "File > Quit")

I can not watch YouTube safari. The video came out black ,but it has sound

I can not watch YouTube on safari. It came out black screen , but it had sound.

Does it work on the YouTube app ? Other people have been posting the same issue with YouTube over the past few days - see if the following help.
Try clearing Safari's cache : Settings > Safari > Clear Cookies And Data (Clear Cache on iOS 4) and also Clear History
If that doesn't work then try closing Safari completely and then re-open it : from the home screen (i.e. not with Safari 'open' on-screen) double-click the home button to bring up the taskbar, then press and hold any of the apps on the taskbar for a couple of seconds or so until they start shaking, then press the '-' in the top left of the Safari app to close it, and touch any part of the screen above the taskbar so as to stop the shaking and close the taskbar.
A third option is a reset : press and hold both the sleep and home buttons for about 10 to 15 seconds (ignore the red slider), after which the Apple logo should appear - you won't lose any content, it's the iPad equivalent of a reboot.

Firefox can not load YouTube Website

I put youtube.com in address bar and Firefox can not load youtube website. It eventually times out. Any suggestions? I have tried clearing the cache, closing firefox and re-opening, downloaded firefox again, and the same problem persists.

You can try to reset (power off/on) the router.
Do a malware check with some malware scanning programs on the Windows computer.<br />
You need to scan with all programs because each program detects different malware.<br />
Make sure that you update each program to get the latest version of their databases before doing a scan.<br /><br />

HT1657 Rent a movie but I can not watch my movie on my iPod why is that

Why I can not watch my movie if I do not have problemes before watching movies

What Adobe Digital app on your iPad? If you are talking about a third-party app (like Bluefire Reader) you need to connect your iPad to your computer, open iTunes, select the iPad, and select Apps in the Sidebar. Scroll down to the File Sharing section, select the app you plan on using, select Add (bottom right), navigate to where the book is on your computer, select the book and sync your iPad.

I bought a HD and the Itunes Stores say that the movie (Pretty Women) has Itunes Extras. Why I can not find it? It is a mistake from Apple? What happen if I buy the movie because the Extras and now I can not watch it? I have an Ipad last generation.

What version of iOS do you have on your iPad (Settings > General > About > Version), and is it connected to wifi ?
From Buy and play movies with iTunes Extras - Apple Support :
Here’s what you need to stream the new iTunes Extras:
Mac using OS X Mavericks v10.9.3 or later and iTunes 11.3 or later
PC using iTunes 11.3 or later
Apple TV (2nd and 3rd generation or later) using Apple TV software 6.2 or later
iPhone, iPad, or iPod touch using iOS 8 or later (You need to connect to Wi-Fi. Extras won't appear if you're connected to a cellular network.)
An active Internet connection
You can use the steps below on your Apple TV, Mac, PC, or iOS device for any purchased, HD movie that features Extras:
On your Apple TV, select Movies, then select your movie to see the Extras menu. Extras aren't available from the Computer tile on Apple TV (Home Sharing).
On your Mac or PC, open iTunes and go to the Movies section in your iTunes library. Double-click your movie. If there's no Internet connection, the Extras menu will be skipped. The movie will immediately play if you already downloaded it.
On your iPhone, iPad, or iPod touch, tap the Videos app, then tap your movie. If you're connected to the Internet via Wi-Fi, the Extras menu will appear.

Vine.co can not watch videos on other browsers do not have the problem with firefox firefox there just did not work, delete cookies, history

vine.co can not watch videos on other browsers do not have the problem with firefox firefox there just did not work, delete cookies, history

I think this problem may be caused by Yahoo's changes making it incompatible with the klatest version of FireFox.
This is suddenly affecting many many people who use Firefox and are members of Yahoo Groups. All these people say they themselves changed nothing and have not been locked out before when using Firefox. But suddenly, within the last week, they are.
What did Mozilla do or what did Yahoo do to cause this problem? I can say that I was not blocking cookies and after trying a number of things to fix it, I went to Yahoo's home page and navigated to my group from here.
This problem is not anything a user did. Either Firefox is at fault or Yahoo is. I want to know which company is at fault and when they are going to fix it.

I can't watch YouTube videos on my brand new MacBook Pro with Lion. It says I need to download Adobe Flash Player but that won't install. Help!

The same thing happens to me, Safari asks me to update the Adobe FlasPlayer, I download, start the installation process, ask me my username and password in order to install, then see a window where I choose if I want to always install the updates , or ask first, or not inslate updates, and at this point it is not progress, I can not cancel the process, I turn off and turn on my machine.
What can I do ..??
Regards.

How can I watch youtube or anything except from airplay.
Thank you for your help!

Welcome to the Apple Community.
Unfortunately, a number of users appear to have encountered this problem. Some of these users have reported that the problem just disappears the following day or shortly after. Other users have found various other solutions to this problem.
Firstly, are you receiving any date and time errors when you turn on your Apple TV?
Check that you are properly connected to the Internet, by ensuring that you have a proper IP address and not one starting with 169. Also check that your location for the iTunes Store is set correctly, if so you might try changing it and then changing it back.
If the problem persists try restarting the Apple TV by removing ALL the cables for 30 seconds, or resetting it using the reset option under general. You should also try restarting your router, or if this doesn't work you might like to try a restore.

Hi, I got the problem with Firefox 27.0.1. I can not run Selenium on Firefox after login a website for automation testing. The browser is not responding.

Hi, I got the problem with Firefox 27.0.1. I can not run Selenium on Firefox after login a website for automation testing. The browser is not responding. However when I close Nunit, the page is back to be normal. The title is returned to the name of website without "not responding". I sure this problem did not happen on Firefox version 26. I just got this problem when firefox upgrading automatically to version 27. Please help me fix this problem because it is very important for my work. If you need more information pls send your concerns via my email address.
Thanks so much

Hi, the work around suggested above should put you in working mode in the meantime. However to help investigate the issue it is possible to analyze what is not loading or taking a long time by analyzing the network traffic or http headers of the Nunit web page.

You can get Firefox 3.6 from http://www.mozilla.com/en-US/firefox/all-older.html
You should still have your profile folder, so when you install 3. you will get your bookmarks and other user data back.
There is a third party version of Firefox that runs on OS X 10.4/10.5 and PPC Macs, for details see http://www.floodgap.com/software/tenfourfox
