How to disable plugin-container


First open Firefox to google or blender nation with all plug-ins/extensions/add-ons un-installed. plugin-container.exe is opened and working memory set is at at over 750mb with over 10,000 handles as soon as it opens Firefox is over 300mb. This has been constantly since updating from 3.5.x Since installing 3.6.13 memory consumption hasn't been as bad firefox.exe is still using 350mb and plugin-container.exe just under 200mb on initial load. This all occurs with only one tab and one window open on load.
