This is probably a different situation, but for me, I discovered just
how much browsers can be greatly slowed down if there are slow/bad
DNS server entries.  Make sure that *all* of your DNS server entries
are good in the /etc/resolv.conf file (can be set with System->
Administration->Network (DNS tab)).  The odd thing is, only the
browsers that were very slow, but everything else seemed to work
fine.  You can check FF against your local web-server just to make
sure it is not a DNS resolver issue or the Internet infrastructure.

For me, FF works well with:

Fedora release 9 (Sulphur)
Kernel 2.6.27.9-73.fc9.i686 i686
Intel(R) Core(TM)2 Duo CPU     E6550  @ 2.33GHz
CPUs: 2
2017MB RAM

... and my daughter's system, also an F9 with a different
and faster Intel Motherboard, Duo-Core, 2GB RAM

FWIW,
Dan
