I HAD THIS PROBLEM ALSO AND FIXED IT BY DISABILING SHOCKWAVE FLASH 11.3.300.257 AND JUST USING 11.2.202.233. BOTH WERE IN MY ADD ONS FOLDER. I love my real player and wont give it up and thankfully it works just fine now. Plays videos and has the little download bar popping right up. Hope this helps you. This problem arose when I upgraded to Firefox 13

I have Shockwave Flash 11.3.300.257 in my Add-ons Manager in the plug in Folder. Is that where you meant. but i dont have the other one.

You can find a download link for Flash 11.2 in this thread: https://support.mozilla.org/en-US/questions/930087

i ALREADY HAD BOTH VERSIONS FOR THE FLASHPLAYER IN MY FOLDER WHEN I UPDATED BUT THANKS ANYWAY jsher2000. Spent 2 days and many relaods to find this simple solution by myself. Tried other methods including the one about using about:config.

I went to the link to download the 11.2 and a window pops up that won't let me load that because it is not the latest offering.

use jscher2000's link above. then go to cor-el's link in the answers. See also https://support.mozilla.org/en-US/kb/flash-113-crashes.

That is what i tried and I got the pop up keeping me from D-loading the 11.2

Wait a minute, do I have to uninstall 11.3 first. I am worried that if I do I am going to mess something up.

I don't know why you are having this problem getting ver11.2. Hopefully someone else will have the answer and post. Like I said I am not a computer guru. And everybodys computer system has differences. Goodluck! ( I have both in my folder and it dosen't conflict for me}
