[Bug 247462] [NEW] Firefox 3.0 consumes more CPU on Ubuntu 8.04 LTS

[Fazlur]

Public bug reported:

Binary package hint: firefox

Hi,
   After upgrading Ubuntu 7.10 to 8.04 LTS, What i observed is, firefox 3.0 consuming more CPU. It also slows down the system performance. Previously i was using firefox. which was good. 

Build details are as follows:

Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.9) Gecko/2008061015
Firefox/3.0

When scrolling the web page, it consume much more cpu. Here is the CPU
consumptions when i did the top.

  Pid     UID      PR   NI    VIRT      RES    SHR    S   %CPU   %MEM      TIME+               COMMAND
 6286  fazlur    20   0    362m   163m   24m   R   76            8.1         607:17.69            firefox

This is not a one time consumption. Till the time the firefox is
running, it consumes more CPU. I have installed some language related
extensions like inidc input extension, Lipikar, Padma and other
extensions like Server spy, show ip and ofcourse session manager.
