Not really a fan of the new plugin-container "feature". If FF crashes on me once every three months, that's a lot, and it's usually something boneheaded I did to cause the crash. I disabled the plugin-container...thanks, but no thanks.
Anyone interested in disabling it, set these five values in about:config all to false, then restart FF
