FredMcD, I can't even disable protected mode, my computer updated yesterday morning and I have hardware acceleration disabled. God I hate Fartwave Crash.

Why can't you disable protected mode?

Start your Computer in safe mode. Then start Firefox.

FredMcD, I just want this piece of junk fixed.

Shockwave Flash is an Adobe product - it's up to them to fix it. All we can do here at Mozilla Support is offer suggestions that have worked for us and other users.

Have you tried Adobe Support? https://forums.adobe.com/community/flashplayer

Mozilla is working an a project code named Shumway - http://mozilla.github.io/shumway/ - that will play SWF files and eliminate the for having the Flash Player installed for Firefox.

the-edmeister, here is my report on the error: https://forums.adobe.com/message/6962585

the-edmeister, I am on Firefox 34 and it still crashes.

Did you disable smooth scrolling as mentioned here? https://forums.adobe.com/thread/1648411 Plus there's two places to disable hardware acceleration; in Flash abd in Firefox.

Also, Adobe has [once again] released a new version of Flash. Version 16.0.0.235 https://get.adobe.com/flashplayer/

Hello people, sometimes I would get the message "Shockwave Flash may be busy or it may have stopped responding". There is no way I can fix this. I have tried Google and they don't show tutorials on how to permanently fix this. What year is this? 2002? Not it's not. It's almost 2015. Can you please fix this for Firefox 34 or newer?

Most people forget about the "Online Setting" you can do http://www.macromedia.com/support/documentation/en/flashplayer/help/settings_manager07.html

I'm now using Firefox 35 and it still crashes.

In Firefox 35 and later you can toggle this pref to true on the about:config page to disable protected mode in the Shockwave Flash plugin:

• dom.ipc.plugins.flash.disable-protected-mode = true

You can open the about:config page via the location/address bar. You can accept the warning and click "I'll be careful" to continue.
