Firefox won't display a google slideshow, but plays youtube videos, using winxp sp 3 and have latest flash installed.

When you hover over the area where the video should be, it shows a message with info about flashplayer, but doesn't show the video.
The video shows up in Explorer 8 and the latest Safari.
Here is the link for the web page I mentioned.. the video is at the bottom after the text..

Why won't Firefox for Android on my Kindle Fire HD play YouTube videos?

The default browser (Silk) on the Kindle Fire HD plays YouTube videos. Both Firefox for Android and Silk obviously use the same operating system and hardware. What needs to be done to/with the Firefox for Android browser so that it will play YouTube videos. Firefox on my desktop machine plays YouTube videos.

There is the old insecure Flash 11.1 Plugin that Adobe (and Google Play) has not supported since Android 4.0. As long as you have Android 4.3 or older then you can get the Flash plugin to work in manual install though Android 4.4 has made it so Flash will not work.
However Mozilla has made a workaround for Flash can still work in Firefox on Android 4.4 in as early as Firefox 27.0 if I recall.
There is this thread on getting Flash installed however the poster mentions Dolphin and not Firefox instead.
http://www.amazon.com/forum/kindle?_encoding=UTF8&cdForum=Fx1D7SY3BVSESG&cdThread=TxTR71JR4GVXQM
Not that some sites (News sites are among some I encountered) have since lately been requiring users using Flash 11.1 on Android, PlayBook and Flash 11.2.x on Linux to upgrade to more current (not possible) to view their Flash videos.

Google tv wont play youtube/videos

I have google tv I can no longer watch any videos or stream music & a pop up comes up stating I need to get flash player , but when I click on the link it says I alredy have flash player instaled on my gooogle chroome browser. So how do I fix this because it wont install something it says I already have? Also I have cleared everything out & restarted the google tv back to factory settings with no results.

Hi ldv22,
It's possible that you could have disabled Flash Player in Chrome. To reenable it:
Type “about:plugins” (without the quotation marks) into the address bar at the top of a Chrome browser window.
Click “Details” at the upper-right corner of the page.
Find the “Flash” (or “Shockwave Flash”) listing on the Plug-ins page and click the corresponding “Enable” button.
Close all Chrome windows and restart the browser.

Firefox won't open my Google calendar but Internet Explorer will. How can I fix this?

Firefox won't load .mov files online but plays them locally: QT problem?

My website has several pages with embedded .mov files, which used to play perfectly well, but now only give a question mark after the progress bar fills up.
For example, one of these pages is http://www.paulozelinsky.com/shivers-animation2a.html
Firefox can open this and similar pages that are stored in my computer (on a mirror of the site) and view the animations normally. But online it doesn't work. Typing the path to the online animation file into Firefox's URL field also produces an empty QuickTime window with a question mark, so it's not a matter of the page code.
Is it possible that QuickTime's plugin isn't compatible with Firefox, at least for .mov files like mine? (Created with After Effects 7, using Sorensen 3 codec). Does Firefox use plugins in the same way for playing a file on a web server as playing it in a local folder? Or could there be something going on with my web host?
I would at least like to know if this failure to load the animation is the same for other Mac Firefox users. I have heard that the animation does load, though slowly, for at least one PC Firefox user.
When I first noticed the change, the problem was occurring in Safari as well as Firefox, but now it is only in Firefox.
I have Firefox 3.6.8, and in HD/Library/Internet Plug-Ins I have QuickTime Plugin.plugin v. 7.6.6. I also see in there something called nsIQTScriptablePlugin.xpt.

Bump, bump. Please can anybody help?

Why when trying to play YouTube videos does it tell me I need JavaScript and adobe flash player but phone doesn't support

Get error message when trying to play YouTube video's say phone don't support adobe flash player but sometimes it plays them

This is because the html5 player will load the video by default. I have noticed lately that some channels required flash player. Do you have an example video by chance for further investigation?

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.
https://support.mozilla.org/kb/Troubleshooting+extensions+and+themes
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.

Answers in this forum have shown different things have worked for different people.
For some clearing YouTube cookies and the cache solved the problem. For details of how to do that see https://support.mozilla.com/kb/Deleting+cookies and https://support.mozilla.com/kb/How+to+clear+the+cache
Others had to go a step further after deleting YouTube cookies and block YouTube from saving cookies. In the Tools menu select Options to open the Options window. Go to the Privacy panel and make sure it is set to "Use custom setting for history". Click the Exceptions button, type in http://www.youtube.com and click on Block
Another option is to disable hardware acceleration for Flash. To do that right-click on a Flash video, select Settings, go to the first tab of the settings for the option to enable/disable hardware acceleration for Flash. This is something recommended by YouTube for those having problems - http://www.google.com/support/youtube/bin/answer.py?&answer=1209379

When I try to play youtube video I get the message of blocked plug-in, and I can not play video using Safari. (Youtube works fine with google chrome) I tried installing flash player HTML5 etc... but still no difference.

I just installed OSX Mountian Lion, and ever since then I can not play youtube video's. I get the message of 'Blocked Plug-in' in the youtube screen. I have tried installing Adobe Flash Player. HTML 5, also tried enabling/disabling java, but nothing worked out. Is there any way I can play youtbe vieos on Safar. (It works fine with Google Chrmoe, only safari has problem)

If you have the ClickToFlash extension installed, that can prevent Flash based video from streaming. Safari > Preferences > Extensions
It can also be installed as a plugin in /Library/Internet-Plug-Ins.
Try uninstalling the currently installled Flash plugin (required for most YouTube content) then reinstall new > Troubleshoot Flash Player | Mac OS
From your Safari menu bar top of your screen click Safari > Preferences then select the Advanced tab.
Select: Show Develop menu in menu bar
Now from the menu bar click Develop > Empty Caches

Frostbitblue,
in Safari’s Preferences, select its Security tab, and make sure that its “Internet plug-ins: Allow Plug-ins” checkbox is checked.

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.

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.

I took some videos using my iPhone 5c and uploaded them to my computer. I can play the videos in iPhoto, but when I open them in QuickTime, they are dark and silent. Why can't I see them in QuickTime?

Make a temporary, backup copy (if you don't already have a backup copy) of the library and apply the two fixes below in order as needed:
Fix #1
Launch iPhoto with the Command+Option keys held down and rebuild the library.
Select the options identified in the screenshot.
Fix #2
Using iPhoto Library Manager to Rebuild Your iPhoto Library
Download iPhoto Library Manager and launch.
Click on the Add Library button, navigate to your Home/Pictures folder and select your iPhoto Library folder.
Now that the library is listed in the left hand pane of iPLM, click on your library and go to the File ➙ Rebuild Library menu option
In the next window name the new library and select the location you want it to be placed.
Click on the Create button.
Note: This creates a new library based on the LIbraryData.xml file in the library and will recover Events, Albums, keywords, titles and comments but not books, calendars or slideshows. The original library will be left untouched for further attempts at fixing the problem or in case the rebuilt library is not satisfactory.
