Brand new HP Pavilion g series laptop. HP Pavilion g6x customizable Notebook PC 

   • Genuine Windows 7 Home Premium 64-bit
   • 2nd generation Intel(R) Core(TM) i3-2330M (2.2 GHz, 3MB L3 Cache)
   • Intel(R) HD Graphics 3000 [HDMI, VGA]
   • 4GB DDR3 System Memory (1 Dimm)
   • FREE UPGRADE to 500GB 5400 rpm Hard Drive

I have Norton 360 installed and keep receiving a notice that Firefox is using a lot of CPU. Last time notice came up it said that Firefox was "100% of at least one CPU". For being brand new my laptop is slow.

What can I do to fix this?

Hi glenhine,

Have you looked at the Knowledge Base article Firefox uses too much memory or CPU resources - How to fix? There is also some good information in Firefox uses too much memory or CPU resources - How to fix.

Hopefully this helps!
