hello, it might be an issue with the protected mode that adobe has introduced for its flash plugin for firefox. please make sure that the security software on your system isn't blocking/sandboxing the communication between firefox.exe, plugin-container.exe and the process for the flash plugin itself).

as a workaround you could try downgrading to flash 10.3 or disabling protected mode & see if this makes a difference.

in case you'd like to troubleshoot the issue further, it would be best to contact adobe's support & file a bug report at bugbase.adobe.com (choose "Adobe Flash Player" as the product & "Browser Integration" as the product area), since they will have a better understanding of the internals of flash protected mode & therefore may know what else might be at the root of the problem you were seeing.

Going back to 10.3 seems to have solved it. Many thanks. I gather Adobe are updating to 11.7 from July 17 2013 so maybe this will resolve it.

I have the crashing problem in FireFox 24.0

It just keeps on crashing randomly.
