More information and further troubleshooting steps can be found in the Troubleshoot Firefox crashes (closing or quitting unexpectedly) article.

If you haven't already, try disabling the protected mode feature added in Flash 11.3. It has security benefits, but is not compatible with all systems for some reason.

You can do that by creating or editing a settings file. The following pages/posts provide different approaches:

• Adobe support article under the heading "Last Resort": Adobe Forums: How do I troubleshoot Flash Player's protected mode for Firefox?

• Manual steps: https://support.mozilla.org/questions/968190?page=5#answer-509209

• Batch file to automate the manual steps: https://support.mozilla.org/questions/982093#answer-518078

Flash needs to completely unload from memory (exiting and starting Firefox up again might help) before this takes effect.
