Shiretoko uses CPU when viewing pages with flash

Asked by Nigel Cundy

Binary package hint: firefox-3.5

I'm running jaunty

When I visit certain websites containing video, even without playing the video (though not every website containing video), the CPU usage for shiretoko goes to 100% and remains there until I close the tab. An example is but I have seen it for several other sites as well. I have noticed no problem in firefox3, epiphany and other browsers, the cpu usage remains normal

dpkg -l | grep firefox

"An example is"

This site is not suitable for any browser... to much information, to many things from foreign sites are loaded through the backdoor... etc.

If so many flash-Applets are to be loaded a Linux System has to struggle a bit, as the display has to be handled by the processor. Its Adobe who lets us suffer indeed.

You should also try opera as a browser. That one is really a lot faster than the others usually used with Ubuntu.

Same thing happens when browsing ubuntuforums for awhile, it uses way too much cpu while loading.
Has anyone found a fix for this?
