Can you provide some steps to reproduce this issue? You start Firefox, and then what happens? Does the issue happen immediately, or after you open some websites (which?) or is it not clear exactly what is triggering the plugin-container memory/cpu usage?

The same is happenig in my system. 

From previous release of Fx 41(beta or aurora) was getting the browser hanging, after a refresh and disabled  oop for flash in mms.cfg and the plugin setting was resolved.

With the release of Fx 41(release channel) the problem got back, I have restricted to the process plugincontainer, kill it and the browser got responsive again.

The hang of plugincontainer is intermitent and don't get any report(doesn't crash).

In related websites say is related to dom.ipc.plugins.asyncInit setted to true, but in my case is false already. Was the flash plugin whitelisted to async comunication?

Perharps i need another option to complete disable the async options for the addons.

The workaround was revert back to Fx 40.0.3
