You Tube videos won't play using FireFox 12

Fire Fox will not play YouTube videos. When I go to the site, I see just a black box with no error messages. The video never loads. I have uninstalled flash player and re-installed with no success in playing you tube videos. IE will play you tube videos! I have disabled all anti-virus, firewall, plugins, etc and FireFox still will NOT play YouTube videos. Please help!

This still did not work. I have noticed that FireFox will not play any video on any website. I am able to play all video using IE browser.

You Tube videos won't run in Firefox, will in Safari!

I can no longer get videos to run in You Tube. I'm running the latest Firefox and Lion. All I see are black shapes. The videos do run in Safari, however. Fix? Workaround? Thanks.

Didn't help. But thanks. Would completely deleting Flash and then reinstalling work?

You Tube videos won't play Windows 8.1, Shockwave Flash, HTML5, updated

I have tried in Firefox, Explorer and Chrome. It doesn't work in any of them using shockwave flash or HTML 5. I did get HTML 5 to work for a little bit but nothing at all is working now. I have a new ASUS computer running Windows 8.1. I installed Cyberlink software which installed Quicktime and I wonder if that has something to do with it.

Try disabling graphics hardware acceleration. Since this feature was added to Firefox, it has gradually improved, but there still are a few glitches.
You might need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.).
Then perform these steps:
*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.
*In the Firefox options window click the ''Advanced'' tab, then select "General".
*In the settings list, you should find the ''Use hardware acceleration when available'' checkbox. Uncheck this checkbox.
*Now, restart Firefox and see if the problems persist.
Additionally, please check for updates for your graphics driver by following the steps mentioned in the following Knowledge base articles:
* [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]]
* [[Upgrade your graphics drivers to use hardware acceleration and WebGL]]
Some problems with Flash video playback can be resolved by disabling hardware acceleration in your Flash Player settings. (See [[Flash Plugin - Keep it up to date and troubleshoot problems|this article]] for more information on using the Flash plugin in Firefox).
To disable hardware acceleration in Flash Player:
#Go to this [http://helpx.adobe.com/flash-player/kb/video-playback-issues.html#main_Solve_video_playback_issues Adobe Flash Player Help page].
#Right-click on the Flash Player logo on that page.
#Click on '''Settings''' in the context menu. The Adobe Flash Player Settings screen will open.
# Click on the icon at the bottom-left of the Adobe Flash Player Settings window to open the Display panel. [[Image:fpSettings1.PNG]] 
# Remove the check mark from '''Enable hardware acceleration'''.
# Click '''Close''' to close the Adobe Flash Player Settings Window.
# Restart Firefox.
This [http://www.macromedia.com/support/documentation/en/flashplayer/help/help01.html Flash Player Help - Display Settings page] has more information on Flash Player hardware acceleration, if you're interested.
Does this solve the problem? Let us know.

You Tube videos will only play at 360p and 240p, no 480p. Was working before yesterday.

Standard definition You Tube videos will only play at 360p and 240p, no 480p. HD videos will play at 720p, no 1080p. It was working until yesterday. I have not made any changes to Firefox. I tried upgrading to the latest version. This is not helping either. I don't have this problem when using Internet Explorer. The problem exists on both of my computers.

hello kmcvety, this should be an issue which is going to be resolved in firefox 36 - you could try it out right now in the beta version:

Hi my computer you tube video won't work every time I watch it says block plug in what does it mean?

HI my computer you tube video won't work and every time I want to watch you tube it says block plug in and also my face book crush saga I used to play all my games now none of it won't work

When you have installed the latest version of Flash Player from Adobe:

MailOnline videos won't play in Firefox unless in safe mode although they're fine in Explorer.

It's for my mum, honest. Firefox 25, java and flash uptodate but the Mail Online videos won't play unless I start Firefox in safemode. A large white rectangle appears but nothing else.

You can try these steps in case of issues with web pages:
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 > Cookies: "Show Cookies"
Start Firefox in [[Safe Mode|Safe Mode]] 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.
If it works in Safe Mode and in normal mode with all extensions (Firefox/Tools > Add-ons > Extensions) disabled then try to find which extension is causing it by enabling one extension at a time until the problem reappears.
Close and restart Firefox after each change via "Firefox > Exit" (Windows: Firefox/File > Exit; Mac: Firefox > Quit Firefox; Linux: Firefox/File > Quit)

Flash Player Update Not Working -You Tube videos will not play!!

I have just updated to the latest ver
sion of Flash Player (10.2.152.32) and now You Tube will not play videos - I get sound only. I am using IE8 and Windows XP SP3
Shockwave Flas Object is showing as installed and enabled.
What is wrong? I have uninstalled and reinstalled and all messages show installtion as complete but still no You Tube video although when I have click Adobe test aniamtion links these work OK

Hi, There is new Technology with the latest Flash Player version that you may need to adjust a Setting.
You may want to go to this site: http://www.adobe.com/software/flash/about/. Right click on the Flash logo, Settings,
then UNcheck the hardware acceleration in Display Settings.
If that doesn't solve the issue, you may need to update your Video card Driver.
Now one thing I'd like to mention is that the Adobe Flash Player Team are wanting to document issues with the latest Flash Player version and issues such as you and others are having. If you would like to give them feedback directly, it would be appreciated as they are trying to duplicate these in house. The link to that is:

Embedded Video won't play in Firefox

I have a youtube video embedded on a website. When played in
IE it's fine, but when played in Firefox the entire page gets
replaced by this error:
Not Found
The requested URL /embed src="

Additionally, a 404 Not Found error was encountered while
trying to use an ErrorDocument to handle the request. "
I do have the newest Shockwave for FF installed on my pc
(10.x) and I've been told that it's not just my FF that it crashes
in.
Here is the link to the video:

Any ideas?

What is the scripting error? Object not found? Did you upload
the Scripts

You tube videos do not play and other sites, ie property, do not display pictures, running 7.0.1

looking at estate agent web sites recently which contain series of pics which you can see as slide shows in an enlarged window do not appear in larger window, but are visable as thumb nails, also you tube videos do not run. This is not the case in internet explorer

Here is a solution for the videos anyway first install the firefox add on Add-on Compatibility Reporter that can be found here
https://addons.mozilla.org/en-US/firefox/addon/add-on-compatibility-reporter/
next restart firefox then install the add on unplug that is found here
https://addons.mozilla.org/en-US/firefox/addon/unplug/
once that is done you might need to make sure that unplug is enabled. if done correctly after its setup you should be able to use the web player you have installed in windows to stream the videos you find on the net.

Certain youtube videos won't play in Firefox

Firefox 20.0.1, windows 7, flashplayer up to date.
Certain youtube videos won't play. The advert beforehand plays, and then the video just displays a black screen, no loading, trying to skip to a later time in the video doesn't work. It seems to be certain youtube users whose videos won't play, users whose videos I was able to watch only yesterday. The featured video on the user's channel is watchable, but not when opened separately.
IE won't show the affected videos either.

In addition to these symptoms, I've noticed that I can view these troubled videos on my cellphone just fine, but neither my XP or Win7 machine, which have all software updated can view. So if it was on youtubes side, it wouldn't work on my phone either.

Videos won't play on Firefox

I have windows vista home edition, 64 bit; I have both IE 9 and Firefox although I mainly use Firefox. I downloaded the latest flash player (11.9.900.170) to both IE and Firefox; the plug-ins are active. Flash player plays on IE but not on Firefox; on youtube nothing displays; there is either a white space or it says the "video is no longer available"
I've removed older versions of flash player and reinstalled; that didn't work; I've removed firefox and reinstalled; that didn't work either; I always seem to have a problem with every new flash player update and firefox.
What am I doing wrong?

Can you post a link to such a video that gives you the error message?

You Tube videos don't play. The site comes up, but a blank white screen where the video should be.

When I try to play videos from You Tube, I get a blank white screen where the video should be. When I go to full screen the whole screen is white. Originally the white screen happened on the expanded view only.
IE doesn't have the problem, but Google chrome and Firefox 4.0 do.

Start Firefox in [[Safe Mode]] to check if one of the extensions is causing the problem (switch to the DEFAULT theme: Firefox (Tools) > Add-ons > Appearance/Themes).
*Don't make any changes on the Safe mode start window.

Try to disable the hardware acceleration in the Flash Player.

Videos won't play in firefox but will in chrome

Have found the solution to my problem, switched to google chrome end of problem.

hello, if you just want to leave feedback you can do so at https://input.mozilla.org/feedback ...
in case you want to troubleshoot the issue in firefox we might need a bit more information of what's going wrong. what happens when you try to play videos - are there any error messages? in addition, could you go to the firefox ''menu ≡ > help ? > troubleshooting information'', copy the contents of that page and paste them here into a reply on the forum? this might give us more of a clue what is going on...

Video won't play in Firefox

A Quicktime video plays perfectly when viewed on Safari, but in Firefox the video is blank. It plays, but only with sound. What do I do?
Here is the page:

Thanks for the help.

I publish all my movies in .m4v file format. Either with QTPro/X "Save for Web" or from iMovie or straight to .m4v in QTPro/X.
Some I convert to to and from flv/wmv with VisualHub/iSquint.
And wmv made on a PC I either convert on a PC with [Format Factory|http://www.formatoz.com> or on a Mac as described above.
They are displayed in Flash Video players, QuickTime and HTML 5.
And you don't need .flv or wmv. Flash/Silverlight players support .m4v files.
Same movie, multiple displays.
And with the advent of HTML 5 I use OGG audio and video.
