I have both those boxes checked & rarely have a problem:
try toggling preferences which look CPU-intensive & see what happens.
Occasionally, I do have a problem with a particular WWW page,
when I have to kill Firefox via 'htop', but it's rare (probably JS).
The 3.0 version was running very slowly on my 2003 machine (AMD Athlon),
but 3.5.2 is as fast there as here on my 2007 machine (Core 2 Duo).

I use Gcc 4.3.2-r3 & have CFLAGS="-O2 -march=native -mtune=native -pipe".
