Adobe released an update on 03/28/2012 and a security bulletin relating to Flash (Player):

Update to Flash (Player) version as recommended to see if that solves your problem.

There are 2 versions of Adobe Flash:

  • an ActiveX version for IE only
  • a Plugin version for most other browsers including Firefox
  • On a Windows system, you should always update both individually.

You do not appear to have the Plugin version for Firefox installed. If you did, in Add-ons > Plugins you would see "Shockwave Flash (version)". If "Shockwave Flash" is there and is disabled, click the "Enable" button.

Check your Plugins often --> http://www.mozilla.org/en-US/plugincheck/

  • only the most popular/used Plugins are known by this page
  • page will detect only installed, enabled Plugins

Install or update Adobe Flash

  1. Using Firefox, go to the following link and SAVE the download to your desktop so you can find it later. Un-check any items on that page that you do not want to download (i.e., "McAfee Security Scan Plus":
  2. When the download is finished, close Firefox (File > Exit OR Firefox button > Exit)
  3. Click or double-click on the file you just saved to your desktop
    • In the installation window that appears, click the box to the left of "I have read and...." to place a check mark in the box
    • The "Install" button in the lower right corner will now be highlighted, click it.
    • The installation is quick.
  4. Start Firefox and test your installation here: https://www.adobe.com/software/flash/about/
  5. To update/install the ActiveX version for IE only, repeat the process, but use IE to go to the above website.

NOTE: Some users of 64-bit systems have found it necessary to download, Save and install (with Firefox closed) the 32-bit Plugin for Firefox manually from the following (4th link labeled "32 bit Flash Player Plug-in (All other browsers)"):

I've downloaded and installed the update to Flash plugin 11.2,202.228,then went through various sites to see what would happen,plugin crashed on CNN,once on Youtube,didn't crash in Yahoo Mail but ads had a hard time coming in which made it difficult to navigate in Yahoo Mail,as to a movie/tv site I watch all the time,plugin crashes frequently,send out report than reload the page,which takes longer now,several seconds,than plug in crashes again,I'm still checking out other sites to see how it responds.I also checked on Internet Explorer 8 just to see how the Active X version worked over there,doesn't crash,but IE is so slow loading up content that it doesn't make a difference.

You might want to follow Adobe's troubleshooting steps of using their uninstaller to remove ALL Adobe Flash from your system. Download/run both 32-bit and 64-bit uninstallers to be sure that something is not missed as the current Adobe Flash installer contains both. Then re-install Flash per the above instructions that I posted.

Also have a look at the information in this Adobe article: http://helpx.adobe.com/flash-player/kb/installation-problems-flash-player-windows.html

Sorry that you are having so many problems with Adobe Flash, but it has become troublesome for many users of late. On my XP SP3 system, I have experienced no problem with Firefox and current Adobe Flash versions.

I followed the above directions you suggested,downloaded the flash uninstaller for 32 bit connection n 64 bit,the 32 bit uninstalled the flash,my computer wouldn't accept the 64 as a legit file,fine,reinstalled the flash plugin for 32 bit connection,latest version and have now gone from just bad to worse,movies won't buffer,than the plugin keeps crashing,so watching movies is out,videos on Youtube kept crashing,plus now the pages hang or freeze,Cnn the same problem,actually it was almost unmanageable,that I finally left the site in disgust.I thought when I came to firefox that my computer experience would be one of enjoyment,but now has become a nightmare.I left Chrome because the browser kept crashing(a common problem I learned),Internet Explorer is so slow you can't do anything in it,so Firefox was a new option,since I don't watch tv,we don't have any video stores near us,plus I'm on a tight budget,plus handicapped,during the winter months I'm on my computer quite a bit and is a great enjoyment for me,I can watch whatever tv shows I want,along with movies,or surf the net,now all that is being slowly taken away from me,I may reconsider going in search of another browser that is hopefully reliable.

Here is some new information about recent Adobe Flash problems. You keep say "crash". Are you actually getting a crash notification or is Flash just not working on some sites or are you getting a message to upgrade to a newer version?

The problem explained in the post below, could be affecting a lot of sites who have not updated their code for the change made by Adobe.

For Yahoo mail, reply from Cww for an explanation and workaround in this post --> https://support.mozilla.org/en-US/questions/924230#answer-323590

Same explanation may apply to other sites not recognizing your installed version of Flash (Add-ons > Plugins > "Shockwave Flash" version); for a workaround, contact the site.

Just noticed 2 things.

  1. You mentioned that you also updated the ActiveX version of Flash; that is for IE only.
    • Are you having problems with Flash in IE also?
    • If so, are the same sites affected.
  2. You posted that you have 224MB RAM
    • Firefox 11 recommended RAM is a minimum of 512MB (see --> https://www.mozilla.org/en-US/firefox/11.0/system-requirements/ )
      • Consider adding more RAM (to see what you need for your system and how much RAM your system will accommodate, visit www.crucial.com and choose your system manufacturer, model series and model number. Print the information. You can look at what crucial has available and look at other sites, like big-box stores, Amazon.com and Newegg.com. Crucial.com has video and/or printed instructions on installing RAM.)
    • Is your processor a Pentium 4?

Another thing, do both "firefox.exe" and "plugincontainer.exe" have the correct permissions set in your firewall?

The latest Active X version is now not on my computer,since Internet Explorer is so slow to respond at the best of times,though I didn't appear to have any problems crashes,just takes to long to get a video to play. When I checked system requirements for Firefox 11 I got a different number for the RAM,it was under 200 but over a 100,don't remember correct number,unless I read something wrong. I did check the www.crucial.com site,they didn't even have my computer manufacturer or system model (Award/AWRDACPI),so that wasn't much help to me. I believe my Processor is (AMD Athlon(tm) XP 2200+) I did check the firewall exceptions,Firefox.exe was there,but not plugin-container.exe,which I've now added. I'll keep working on finding my computer manufacturer, an required info
