Firefox cannot download youtube video

firefox can play youtube video but it doesn't show real player download pop-up window and cannot download with real player.

I found that the plugin container for Firefox will not work with the Real media plugin. It crashes every time. Firefox itself handles the plugins just fine, so I bypassed the plugin container for that plugin by adding a setting in the about:config window setup.
* dom.ipc.plugins.enabled.i386.<name of plugin> - set to false
You can find the names of the plugins by typing about:plugins into the address bar and hitting the Return key.
Another thing you can do is set Firefox to hand off to the Real Player as a helper application to play the media, from Options > Applications.

I used to watch n download YouTube videos on Firefox till ystday. Now, the videos wont play and the download stopped working, while the videos do play on Chrome

I used to watch and download YouTube videos on Firefox. Since yesterday, videos have stopped loading, and an error message is shown saying videos can't be played. When I click on the download button, a new page pops up (which never used to happen before) which says "Server not found: Firefox can't find the server at r12---sn-h557sne7.googlevideo.com."
I have tried almost all suggestions found in various forums. The problem is not yet rectified. Its irritating.

You can try these steps in case of issues with web pages:
You can reload web page(s) and bypass the cache to refresh possibly outdated or corrupted files.
*Hold down the Shift key and left-click the Reload button
*Press "Ctrl + F5" or press "Ctrl + Shift + R" (Windows,Linux)
*Press "Command + Shift + R" (Mac)
Clear the cache and cookies only from websites that cause problems.
"Clear the Cache":
*Firefox/Tools > Options > Advanced > Network > Cached Web Content: "Clear Now"
"Remove Cookies" from sites causing problems:
*Firefox/Tools > Options > Privacy > "Use custom settings for history" > Cookies: "Show Cookies"
Start Firefox in <u>[[Safe Mode|Safe Mode]]</u> to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem.
*Switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance
*Do NOT click the Reset button on the Safe Mode start window

I cannot open youtube videos to full screen after downloading the latest version of flash. HELP

I cannot open youtube videos to full screen after updateding flash to the latest version (11. something) HELP! youtube says it is adobe's problem

To help troubleshoot we'll need the following system information:
Operating   system
Browser
Flash   Player version
When reporting issues with video or audio, it's also helpful to get your system hardware and driver details. Instructions for finding this information can be found here:
Windows
Mac
Finally, sometimes video and audio problems are caused at a lower level and not directly related to Flash Player. I recommend trying both of the links below to see how they perform. If the problem exists with both, then Flash Player is most likely not the culprit as the HTML5 video link does not use Flash Player when playing. You can verify the use of HTML5 by right clicking the HTML5 video and looking for the words "About HTML5" at the bottom of the context menu.
HTML5   video
Non-HTML5 video

I CAN NOW... NOT DOWNLOAD YOUTUBE VIDEOS AFTER UPGRADING TO THE NEWEST VERSION OF ADOBE FLASH PLAYER

LETS SOLVE THIS RIGHT NOW! I UPGRADED TO THE NEWEST ADOBE FLASHPLAYER AND NOW I CANNOT DOWNLOAD, USING MY REALPLAYER, ANY YOUTUBE VIDEOS WHICH I HAVE ENJOYED DOING FOR THE LAST, LIKE, 5 ******** YEARS!!!! MY FAITH IN ADOBE HAS JUST BEEN SHATTERED! PLEASE KEEP ME AS AN ADOBE CUSTOMER AND KEEP ME FROM SCREAMING BLOODY MURDER. FIX THIS PROBLEM PLEASE!!!

That's NOT (Repeat: NOT) a Flash Player caused phenomenon. YouTube is converting ALL their videos to HTML5 and RealPlayer (which is pure unadulterated garbage IMHO) isn't able to download them now, and won't be able to until they update their software to handle the format change.
Since Adobe DOESN'T run YouTube (Google does) they can't do anything about this. YOU CAN.
If you use Firefox, you can download AntVideoDownloader and use it to download YouTube videos.
1. It's a plugin, and NOT a full applicaiton, so it takes up less space on your HD.
2. It works with Flash Player (unlike RealPlayer which is a competitor program)
If you don't use Firefox, sorry. AntVideoDownloader DOESN'T work with IE, or Chrome.

How to download youtube videos to ipad without using a computer.

How to download youtube videos to ipad without using a computer??? Looking to download some videos people created using Dr. Jean music. My kid used Dr. Jean in preschool and wanted to keep singing them at home.
Looking for a friend that doesn't use a computer. I myself have downloaded some kids educational stuff and added to itunes and then put on ipod/ipad using firefox.
Is there an easy way, so they don't go to the photo roll??
thanks in advance.

There are some Apps you can use, but be careful they will only download these videos inside the App, so you won't ba able to play them in your video app or share them.
Most popular is the app called "Video Download" but there are a lot of alternatives for free and even with more quality which you can pay for.

"Activity window" in Safari no longer works to download YouTube videos. Why not? Workaround?

For years I have used Apple's recommended standard technique whenever I wanted to download a Flash video embedded in a YouTube page to my hard drive:
- Open a YouTube page and click on the video's "play" button to get it started;
- Press command-option-A to then open up Safari's "Activity Window" which lists all the components of the page;
- Find on the list the component for the loading Flash video, which is usually much larger (measured in MB rather than KB) than all the other components, and also is usually still in the process of loading, so it's easy to spot;
- Double-click the component's name on the list in the Activity Window, and voila, the video downloads to my hard drive.
This "trick" is described everywhere as THE standard way to download YouTube videos (and similar page components); and I have used it successfully for many years.
HOWEVER, sometime very recently (not sure when, exactly -- a few weeks or months ago) YouTube has changed the way its pages are coded, so that this technique no longer works. When I open the Activity Window, instead of seeing one large loading video file that's easily identifiable, I see a whole series of large files, all exactly 1.7mb big (no matter how large the file size of the actual video in question is), and they constantly increase in number -- at first there are two such files, but over the seconds and minutes more and more appear. Furthermore, many files with no named size are constantly loading and then disappearing. And here's the whole point: I've tried double-clicking on ALL of these files, dozens of ways on dozens of YouTube pages, and none of the are the video file I seek and none of them cause the file to download to my hard drive.
If I click on one the mysterious 1.7mb components, I indeed get a ".flv" downloaded to my hard drive, but it's not actually a Flash video; clicking on its downloaded file icon just brings up a blank box or an error message saying that it's not really a video file at all. I think it's some sort of "decoy" file or something to do with streaming Flash code.
To see what I mean, just go to YouTube, load any random video page, and then open Safari's Activity WIndow and try to download the video that way.
This happens on an iMac running Safari 5.1 on OSX 10.6.8, and also on a MacBook Pro running Safari 5.0.2 on OSX 10.6.5, and on a few other new-ish Macs I tested it out on, but failed to note their version numbers.
I'm presuming that this problem is not specific to my computer, but is caused by the way that YouTube altered the background code for their pages. I don't know if the glitch is an intentional attempt by YouTube to prevent downloads, or if it is an accidental "bug" of the new code. Either way:
How can I fix the problem? Is there some other lesser-known built-in way for Safari/Mac to download the new kind of YouTube videos? Or is there some reliable freeware or shareware or plug-in or extension or whatever for Safari that would enable YouTube downloading?
I tried a freeware program called "Evom" that was highly touted, but it too was thwarted by the new YouTube code and failed to extract any videos from the YouTube page, even though that's what the application was designed to do.
As a side note, I will say that I also have (though rarely use) FireFox for Mac, and the "Unplug" plug-in installed on it, and that ALSO "broke" recently and no longer has the capacity to recognize or download YouTube videos, even though previously it worked fine. This is why I think the issue is not specific to my set-up or computer, but is due to a change in YouTube's underlying code.)
Any help with an explanation, solution or workaround would be much appreciated (by me and by millions of others who I assume are facing the same problem!).

Carolyn:
I just now did exactly as you recommended. Result? No change.
Even after trashing the files and restarting and everything else, the Activity Window and YouTube behave exactly as they did before.
(I had actually previously tried something very similar to your recommendation, and it didn't have any effect then either.)
In case it's helpful, here's an example of what one of the mystery components that load endlessly in the Activity Window is listed as:

I have a macbook pro running snow leopard. Just recently I cannot view youtube videos and other online videos. I recently updated my flashplayer plugin and I believe that is the problem. Is the latest flashplayer plugin compatible with 10.6.8?

I have a macbook pro running snow leopard. Just recently I cannot view youtube videos and other online videos. I recently updated my flashplayer plugin and I believe that is the problem. Is the latest flashplayer plugin compatible with 10.6.8? If this is so, I need to find an older flash player plugin to reinstall. I do not want to upgrade from 10.6.8 at this time because I have 18 yrs. worth of financial records on Quicken that I have read will not work with Lion and I've read bad things about running music programs on Maverick.

1) Quicken 2007 for Intel (Snow Leopard, Lion, Mt. Lion and Mavericks) is a full featured app that can be downloaded from Intuit for $15 and will work with your data file if you are using Quicken 2005, 2006 or 2007 (if you version is earlier, let me know for more instructions on easy conversion):
http://quicken.intuit.com/personal-finance-software/quicken-2007-osx-lion.jsp
2) Partition your hard drive, or add an external hard drive and install Mavericks there and "dual-boot" to operate your music programs in Snow Leopard and experiment with them in Mavericks.
DO NOT install Mavericks over Snow Leopard!

Cannot dowload YOUTUBE Videos through RealPlayer anymore since your update...I can through IE, which I hate!

Since I updated to Firefox 5.0 , I am unable to download YOUTUBE Videos through RealPlayer...that download Icon has disappeared. I opened I.E. and guess what! I can still download through them...however I absolutely HATE I.E. and love Firefox.
What has changed? What did you guys do?

Dear Pat, please forgive my total ignorance about programs. I'm confused as to why when I had only my Windows Media Player with a plain Adobe I could watch all videos and such, and now suddenly I can't watch them unless I install the Adobe Flash Player and a number of other programs too???
I try to avoid using up so much more memory as programs take, as my computer is pretty old (though works well) and it doesn't have much capacity for installing more memory.
"If you want to play Youtube videos, you will need Adobe Flash Player."
If there's no other choice, I'll install Adobe Flash Player, but will this be sufficient to view videos/Youtube, etc. without having to install more programs?
"If you want to play downloadable videos such as MPEG files, you will need Windows Media Player."
Does "downloadable videos such as MPEG files," mean to copy a video to another place via downloading it? I wondered how to do that when sometimes people ask me to email them a video and didn't know I could use the Windows Media Player which I already have...
"For other file formats you may need other players such as QuickTime or Real Player."
Would you kindly tell me which are the "other file formats" and how can I tell if they are really necessary for me?
"To see what version of Flash Player you have, click on this link http://www.macromedia.com/software/flash/about/ "
I must not have it since each time I try to open a video or Youtube it doesnt let me view it and a flashing popup urges me to "GET THE LATEST FLASH PLAYER".
"P.S. If you don't need/use Adobe Photoshop Album Starter Edition, you can uninstall it from Add/Remove Programs."
Thank you for telling me, I've uninstalled it and am happy! :) Also thank you for alerting me to NOT install Adobe Media Player.
So far I haven't been able to open any of the videos, Youtube, etc. I receive, so will appreciate it so much if you and/or others could help me understand this, for which, my deepest thanks!! :) Adela

Cannot play youtube videos

I cannot play Youtube videos on my MacBook Pro. I am using Safari. I checked to see if Google had signed me up in their test program and I am not. The apple store upgraded flash.
Any ideas?

If you are trying to view YouTube content from Safari, that requires Flash which cannot be installed on an iPad.
A workaround would be to download the You Tube app > YouTube for iPhone 3GS, iPhone 4, iPhone 4S, iPhone 5, iPod touch (3rd generation), iPod touch (4th generation), iPod touch (5th generation) and iPad on the iTunes App Store

Formerly I could download YouTube videos by double clicking the largest size page element in the Safari activity window address column. Now in V 5.0.5 page elements are not shown, just the page title, and under that about:blank. Suggestions? Thanks.

Formerly I could download YouTube videos by double clicking the largest size page element in the Safari activity window address column . Now in V 5.0.5 page elements are not shown, just the page title, and under that "about:blank". Also, the activity window used to show sequential activity and now each new page replaces the last. Thanks for any suggestions re how to restore previous activity window function.

Not all YouTube videos are available for downloading, but:
There is the Free iTube Grabber which can capture almost any audio and/or video stream (it says here) but only works with Intel Macs.
http://itube-grabber.en.softonic.com/mac
Firefox Download Helper is also supposed to work, you have to be logged into YouTube first.
and the RealPlayer Downloader that comes with RealPlayer SP for Mac from:
http://www.real.com/realplayer/mac
which also downloads videos from YouTube.
There is also iTubeX which allows you to download videos (Flash, HTML5 and others), .mp3 and .swf files from almost every website as easily as possible:

how to download youtube videos on Macbook Pro?

If I told you how, I'd also have to get rid of this thread. We can't discuss how to circumvent copyright restrictions, and many Youtube videos have just that.

With ios 7.03 I cannot expand youtube videos to screen size but get white blanks all around the stream

since the update to ios 7.0.3 I cannot expand Youtube videos to screen size - instead, the features around the video dissappear and are replaced by white fields. With my ipad mini I do not have that problem.
Does anybody know advice?

Reset the device:
Press and hold the Sleep/Wake button and the Home button together for at least ten seconds, until the Apple logo appears.
If that doesn't help, tap Settings > General > Reset > Reset All Settings
