Flash crashing since Flash update to 11.5 and Firefox update to 17.

About 4 days ago, Adobe Flash Player updated to 11.5 and started crashing multiple times a day. So when Firefox updated to 17 today, I immediately uninstalled Firefox and reinstalled the new versions in hope that the problems would be fixed. When that wasn't the case, I followed all the steps for Flash 11.3 and nothing has worked. This is only happening in Firefox. Flash works fine in Google Chrome and in Internet Explorer. My school's primary requirement is that I use Firefox with Flash to do my schoolwork. This is an issue if I have to restart Firefox multiple times during my session. 25% of all Flash crashes also crash Firefox. I need help soon.

The problem seems to be caused by Firefox's Protection Mode. I think I have a fix, but I'm hesitant to post it at the moment. I want to give it a day or two to see if there are any other problems. But if anyone is that desperate for a fix, Google "Disable Firefox Protection Mode" and that will give you instructions on how to do it.

Has anybody figured out how to fix Adobe Flash 11.5 with Firefox 17? Every site I go to, flash crashes. I'm trying to get some games played on pchgames.com and can't because flash is crashing MORE NOW than ever before. I even tried to submit a couple of screen shots but they're not being accepted.

You can check for problems caused by recent Flash updates and try these:

  • disable a possible RealPlayer Browser Record Plugin extension for Firefox and update the RealPlayer if installed
  • disable protected mode in Flash 11.3 and later
  • disable hardware acceleration in the Flash plugin

None of those things worked. I even changed an integer in the program of Flash and nothing has helped. Still crashing like a son of a bitch.

I have this same problem and at one point was loading flash player plugin twice in processes. It loads 2 as normal. I was loading 4. What it does now is it seems to work normally then suddenly it is going wild using 100% of the CPU and locking everything up so i have 2 exit using task master and end the plugin process. which ends FF . Also has caused at least 3 cases of blue screen. The problem seems 2 be in the way the plugin handles flash player input and other CPU activity at the same time. Like it lost its' braking power and just floor the flash player content to the CPU.

thanks SilverWolf

Looks like NOBODY has ANY real solutions as to why Adobe Flash 11.5 keeps crashing like a son of a bitch.

Has ANYBODY been able to contact Adobe and tell them that the latest version of Flash Players is ****** and to come up with a different version?

Edited for language. See Forum rules and guidelines. aw

Does anyone know if this would work? I've never done anything like it so I'm a little apprehensive.

"You can disable Protected Mode in Flash 11.3 and above by adding the line ProtectedMode=0 to the Flash "mms.cfg" file located in:

   (Windows 32bit) C:\Windows\System32\Macromed\Flash 
   (Windows 64bit) C:\Windows\SysWOW64\Macromed\Flash 

For example, on a Windows 7 64-bit system, open the C:\Windows\SysWOW64\Macromed\Flash folder, copy the file "mms.cfg" to the desktop, open it in Notepad, add a new line ProtectedMode=0 and then close Notepad, saving your changes. Next, go back to the C:\Windows\SysWOW64\Macromed\Flash folder, rename the original file to "mms.cfgBAK" (to save it as a backup) and then drag and drop in the modified "mms.cfg" file from the desktop"
