whatwhere is the plug-incontainer? happened to the plug-in container? it disappeared with the latest version and now firefox freezes multiple times each day.

I don't see the plug-in container in the Windows Task manager since the last update of Firefox and now FF is freezing multiple times a day (since the previous update, before yesterday's). It takes several minutes after I see this until it unfreezes, and it's quicker to "end task" and re-start Firefox than wait. This most often seems to happen when the computer's been idle for awhile, rather than when I'm using it.
