You can check for problems with current Flash plugin versions 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

Also make sure that you have the latest divers for your graphic display card.

I had the same problem. I disabled protected mode and hardware acceleration, and now it seems to work :)

See Adobe Flash plugin has crashed - Prevent it from happening again - Solution 2 Downgrade to Flash 10.3.

I uninstalled Flash Player and Flash Plugin using Windows Control Panel (Programs and Features) then installed Flash Player 10.3.

the thing is, flash player 10.3 has been block-listed. i installed and re-intalled 11.6 and it worked for two days and then started freezing again. i am going to try fixing the protected mode thing. i hope it works though.

Does it work for you kanau? It worked several days for me, but to day the problem was back again but now it was even worse. Now Flash Player freezes Firefox completely.

i didnt do anything with the hardware acceleration but i did fix the protected mode and it has been running well. i will report again should anything happen. like the stupid freezing thing.

Given how much problem Flash-player has been for almost an year by now, wouldn't it be easier for all involved if it became built-in feature, like PDF did since the latest update?

Is there anywhere a dumped down for amateurs version/explanation to disabling protected mode? I'd rather not try something I don't know how to reverse...

The link posted previously by cor-el is pretty straightforward I think. It also tells you how to do if you want to reverse the process. Look for "Disabling Protected Mode in Flash 11.3"

Unless mms.cfg is a secret/hidden file, I don't see it. So that way doing things is a bust.

I see only FlashInstall.txt, flashplayer.xpt, FlashPlayerUpdateService, FlashUtil32_11_2_202_235_Plugin, NPSWF32_11_2_202_235.dll. which one of thses am I supposed to work on?

more options

None of them. That's strange, I have "don't show hidden files" checked and I can see it. Perhaps if you check " show hidden and secret files" in windows, you can see it?

or if you use 7 perhaps this will help I don't know, I use vista.

Found this on another place here on the forum

"If the mms.cfg file does not exist, create one using any standard text editor (e.g.. notepad)"

Go there and have a look:) https://support.mozilla.org/sv/questions/941748

So just creating a mms.cfg in txt-file with nothing but ProtectedMode=0 does the thing?

It seems so, i don't really know. You could give it a try.?
