Windows uses a different version of the flash player then Firefox.

If you have problems with current Shockwave Flash plugin versions then check this:

• see if there are updates for your graphics drivers

• disable protected mode in the Flash plugin (Flash 11.3+ on Windows Vista and later)

both you guys are missing the point...HOW DO YOU DISABLE HARDWARE ACCELERATION IN FLASH WHEN YOU CANT GET TO THE FLASH MENU...ITS CRASHES WHEN YOU TRY TO GET THE GRAPHIC SO YOU CAN RIGHT CLICK TO GET TO THE MENU.....IM IN A CATCH 22 HERE btw I installed Waterfox which is the 64 bit equivalent of firefox which uses the same plugins and addons and same profile and it works FINE so the problem is with firefox NOT the flash player. I'm not new at this , sorry but I'm a little frustrated at this point.

Open your file browser to this folder; C:\Windows\SysWOW64\Macromed\Flash

Locate (or create) this file and open it in Notepad. Add this line;

ProtectedMode=0

Sorry, forgot the filename.  :-/

Open mms.cfg

You can disable protected mode in the Flash plugin via the Plugins Add-ons page (about:addons)(Tools > Add-ons > Plugins). See:

FredMcD - thanks the additional line added to the flash folder worked and Adobe flash is working again

Glad to help. Safe Surfing.
