[ubuntu] plugin container pushes cpu % to above 70 or 80

view story

http://ubuntuforums.org – when using firefox 16, a lot of times it's flash plugin-container child process hogs cpu power and raises it's percentage to numbers above 70 or 80 (as I see when using the program "top" in the terminal) even when no firefox tab i have open is using flash player, I'm using the latest version of flash, via 11.10's update manager, and the fan (i'm assuming) is noticeably louder for long periods of time. There's no performance problems that i notice, but it's very annoying and i feel this is being really hard on my laptop and overstressing and overheating it. Is anyone else having this (Hardware)
