If the site requires flash, did you already try to disable it and see, if firefox uses still so much CPU?

[arab80ps (arab89ps)]

every thing right without flash player

but the same website goes perfectly when i use opera and flash

[goto (gotolaunchpad)]

Do you use gnash or the original proprietary flash?

[arab80ps (arab89ps)]

i use adobe flsh player 10

[goto (gotolaunchpad)]

From the ubuntu repository? Or downloaded from the flash site?

[arab80ps (arab89ps)]

from Ubuntu repository

[goto (gotolaunchpad)]

Then this bug should be filed against adobe-flashplugin.

[goto (gotolaunchpad)]

Or maybe flashplugin-nonfree? I'll change that. If anyone knows better, please correct.
