Then use add-block.

Firefox also uses a lot of CPU here on my old laptop. I try not to use
too many extensions, they usually eat a lot of power too.
I minimised my extensions to add-block and no-scripts, which tunes
down the CPU usage. Especially no-scripts is great, my CPU load for
Firefox 3.0.3 is below that of the X server and stays at about an
average 10%, with about 10 open tabs.
Also avoid automatic tab reloads, this is very power consuming.
