== This happened ==
Every time Firefox opened
== don't know

What does the Adobe test page say?
http://www.adobe.com/software/flash/about/
Start Firefox in [[Safe Mode]] to check if one of your add-ons is causing your problem (switch to the DEFAULT theme: Tools > Add-ons > Themes).
See [[Troubleshooting extensions and themes]] and [[Troubleshooting plugins]]
If it does work in Safe-mode then disable all your extensions and then try to find which is causing it by enabling one at a time until the problem reappears.
You can use "Disable all add-ons" on the ''Safe mode'' start window.
You have to close and restart Firefox after each change via "File > Exit" (on Mac: "Firefox > Quit")

  • Ever since upgrading to Mavericks, Adobe Flash Player doesn't work.

    I upgraded from Snow Leopard to Mavericks recently and since then, sites do not recognize that I have Adobe Flash Player installed at all. I currently have the most updated version: "Plug-in version 11.9.900.170 is installed." I noticed this when family and friends sent me e-cards. I go to the sites to view them and it tells me I need to download Adobe Flash Player.
    I have uninstalled it twice and downloaded it twice. Installation is always successful and complete but when I test it to view an e-card sent to me from a reliable site, it still states that I need to install it to view the card. I HAVE IT!! lol  I don't understand why the sites are not recognizing it on my computer.
    I've tested it out on both Safari and Firefox and it doesn't work on either. Safari is 7.0.1 (current).
    Can anyone help me fix this? Troubleshooting on Adobe Flash Player basically tells me to uninstall and re-install. Still doesn't help. ~sigh~
    Thanks in advance for any help!

    If you're sure you've installed the latest version of Flash, take each of the following steps that you haven't already tried. After each step, relaunch Safari and test. For a "missing plug-in" error, start with Step 5.
    Step 1
    If you're only having trouble with YouTube videos, sign in to your YouTube account and load this page. You may see a link with the text "Leave the HTML5 Trial." If so, click that link.
    Step 2
    If you're getting a "blocked plug-in" error, then from the menu bar select
     ▹ System Preferences… ▹ Flash Player ▹ Advanced
    and click Check Now. Quit and relaunch your browser.
    Step 3
    Triple-click anywhere in the line below on this page to select it:
    /Library/Internet Plug-Ins
    Right-click or control-click the highlighted text and select
    Services ▹ Open
    from the contextual menu.* A folder should open. Delete the following item, or anything with a similar name, if present:
    Flash Player (failing).plugin  
    You may be prompted for your login password.
    *If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combinationcommand-C. In the Finder, select
    Go ▹ Go to Folder...
    from the menu bar, paste into the box that opens (command-V). You won't see what you pasted because a line break is included. Press return.
    Step 4
    Re-download and reinstall Flash. Download it from the domain "get.adobe.com". Don't click a link from any other website, including this one, because you can't trust links. They may be an attempt to trick you into installing malware masquerading as Flash. Type the address into the browser window. Never download a Flash update from anywhere else.
    Step 5
    If you get a "missing plug-in" error, select
    Safari ▹ Preferences... ▹ Security
    from the Safari menu bar and check the box marked
    Allow (or Enable) plug-ins
    Then click the button marked
    Manage Website Settings...
    if present and make sure that the website is not blocked for Flash.
    Step 6
    Select
    Safari ▹ Preferences... ▹ Extensions
    from the Safari menu bar. If any extensions are installed, disable them.
    Step 7
    In the Safari preference window, select
    Privacy ▹ Remove All Website Data
    Close the window. Then select
     ▹ System Preferences… ▹ Flash Player ▹ Advanced
    and click Delete All. Close the preference pane.

  • Is it correct that "Shockwave" (an Adobe plugin) is necessary for viewing YouTube etc.? If so why can we never find Previous versions for Firefox, when a BIG problem is found, as with new Adobe Flash Player 10.2 FF Plugin??

    Flash Video NOT working of Facebook YouTube etc...
    Adobe Flash Player 10.2 (Latest) is the problem..
    installing and uninstalling Doesn't resolve the problem.
    A Rollback to Earlier Version DOES work...

    Adobe Flash player, previously known as Shockwave Flash is required for YouTube videos. You can get earlier versions from http://kb2.adobe.com/cps/142/tn_14266.html

  • How come adobe flash player does not work on my macbook air

    when on yahoo and i select to watch a video it doesn't play and any other website with a similar format.
    But i have downloaded and installed adobe flash player but yet i am still experiencing these problems. Is there another way or am i just missing something?

    If you can't install or update Flash, follow these instructions.
    If you have installed the latest version of Flash, please take each of the following steps that you haven't already tried. After each step, relaunch Safari and test. For a "missing plug-in" error, start with Step 8. Back up all data before making any changes.
    Step 1
    You might have to log out or restart the computer before a Flash update takes effect.
    Step 2
    From the Safari menu bar, select
              Safari ▹ Preferences... ▹ Privacy ▹ Remove All Website Data...
    and confirm. Close the window. Then select
               ▹ System Preferences… ▹ Flash Player ▹ Advanced ▹ Delete All...
    In the sheet that opens, check the box marked
              Delete All Site Data and Settings
    then click Delete Data. Close the preference pane.
    Step 3
    If you're only having trouble with YouTube videos, log in to YouTube and load this page. You may see a link with the text "Leave the HTML5 Trial." If so, click that link.
    Step 4
    a. If you get a warning of a "blocked" or "outdated" plug-in, then select the Security tab in the Safari preferences window. In the list of plugins on the left, there should be one—and only one—entry for "Adobe Flash Player," showing the same version number that you installed. Select that entry. On the right there will be a list of websites for which you have specifically allowed Flash, if any. It's normal for the list to be empty. Below that is a menu labeled
              When visiting other websites
    From that menu, select either Allow or Ask.
    b. If you still get the alerts, then go back to the Flash Player preference pane and select the Advanced tab. Click Check Now. Quit and relaunch the browser.
    c. If the alerts still persist, triple-click anywhere in the line below on this page to select it:
    /System/Library/CoreServices/CoreTypes.bundle/Contents/Resources
    Right-click or control-click the highlighted text and select
              Services ▹ Open
    from the contextual menu.* A folder should open. Inside it, there should be a file named "XProtect.meta.plist". If that file is missing and you know why it's missing, restore it from a backup or copy it from another Mac running the same version of OS X. Otherwise, reinstall OS X.
    *If you don't see the contextual menu item, copy the selected text to the Clipboard by pressing the key combination command-C. In the Finder, select
              Go ▹ Go to Folder...
    from the menu bar and paste into the box that opens by pressing command-V. You won't see what you pasted because a line break is included. Press return.
    Step 5
    In the Safari preferences window, select the Advanced tab and uncheck the box marked
              Stop plug-ins to save power
    Step 6
    Open this folder as in Step 4:
    /Library/Internet Plug-Ins
    Delete the following item, or anything with a similar name, if present:
              Flash Player (failing).plugin
    You may be prompted for your login password.
    Step 7

  • Adobe Flash Player does not work with Safari. What can I do?

    Hi,
    I have a MacBook Pro, Retina, 15 inch, late 2013,  2 GHz Intel Core i7, using OS X 10.9.4. I have installed Adobe Flash Player. In my System Preference, in the advanced settings, it is set to install updates also tells me that I have the NPAPI Plug-in (version 14.0.0.145) installed but not the PPAPI Plug-in. Is this the reason why it does not work with Safari (keeps telling me to download the app, which I did but still does not work)? Is there any way I could fix the problem? Please, help.

  • Adobe Flash Player 11 NOT working after several attempts to download, uninstall, & reinstall

    I have problems with Adobe Flash Player 11 NOT working after several attempts to download, then uninstall, & re-install. 
    I uninstalled the previous versions of Adobe Flash Player from my computer PRIOR to attempting to install the new 11 version, so now I'm unable to view videos, etc., 
    I'm using Windows Vista 32 bit, Internet Explorer 9.0 (which I closed when I got error messages during Adobe Flash Player 11 Installation.  I've  disabled my AVG -Virus also during the installation of Flash Player 11.   
    FYI, I'm not computer savvy so the YouTube video by Adobe Tech was too complicated to follow AND I'm unable to view  (DUH!) it since I have no Flash Player program installed (doesn't make sense!) .
    Thanks for keeping it simple (KISS for me).

    I've tried uninstalling and reinstalling some 30 times now ..rebooting, you name it.
    I haven't been able to use flash since Adobe kindly shoved that latest update down my computer's throat.
    Right after getting the 'successful' installation message I restart IE9 ..go to my channel on youtube and immediately get the message:
    The Adobe Flash Player is required for video playback.
    Get the latest Flash Player
    I tried Chrome and on two or three it worked but then even after closing out of them ..Chrome slowed down to a crawl and finally informed me that Flash had stopped working.
    This has entirely wasted 3 nights of my time. It is 2:30 am and I should have had at least 2hours sleep already to rise at 6:30 but no, thanks this I'm still up and no doubt millions of other computer users are having just as much fun.. Everyone I know that allowed the updates to install ..is having the same problem ..Chrome/IE9/Firefox ...you can truly call it Adobe's Universal Cluster ...
    I live with Adobe. At work we have 6 fully Adobied LR4/CS5 & 6/InDesign workstations. I'm a photographer using nothing but Adobe products and quite frankly I feel this is the worst treatment you have ever given your customers.
    Please stop the CYA and just fix the damm thing! I realize you didn't write it Chris but surely you can get Adobe management to address this instead of just trying to get their users to try and debug it for the airheads that released it. Has anyone stopped to consider the financial damage being done due to videos not playing the ads that support the sites and no doubt stream revenue to Adobe? These guys have rolled the online experience back 5 years minimum and Adobe will probably pay the price for it. Re-issue a working version and go back to the drawing board!

    Hi, Your Flash files are all correct for IE. I'm sure they are also for FF, since Flash Player is working.
    What you can try is something that has helped other users and maybe this will help you with IE. Try turning off the User Account Control and then Restart your computer and see if IE is working now.
    Open User Accounts by clicking the Start button , clicking Control Panel, clicking User Accounts and Family Safety.
      and then clicking User Accounts. Click Turn User Account Control on or off.
      If you are prompted for an administrator password or confirmation, type the password or provide confirmation.
      Select the Use User Account Control (UAC) to help protect your computer check box to turn on UAC, or clear the check box to turn
      off UAC, then click OK.
    Let me know whenever you can, no hurry.
    Thanks,
