When I installed Ubuntu on a laptop at home, my Internet performance was horrible.  I had installed Ubuntu before, but never had any issues.  I then installed Etch, same issue, same laptop.  I tried other OS's without any success.  I then tried an older version of Debian and it worked fine.  I searched Google and found a little blurp about window size and routers and the newer kernels.

I don't know if this will help you, but with the machine running, open a terminal window, go to root mode and cat /proc/sys/net/ipv4/tcp_window_scaling.  If it is set to 1, change it to 0 with echo "0" > /proc/sys/net/ipv4/tcp_window_scaling.  Close FF and try again.

The difference was night and day for me. 

There are a few work arounds, but if this works and you want a permanent solution, add "net.ipv4.tcp_window_scaling=0" to /etc/sysctl.conf.

I know there are other settings, but this worked well for me.

When firefox doesn't connect, what does the status bar say it's doing? 
looking up host, waiting for reply?

What's the output of "ifconfig -a" ?

If there are any errors, it's my typing.  This is worse than sneakernet; 
I couldn't figure a protocol to write the ./ifconfig -a output to a 
floppy and then cut and paste in WinXP Thunderbird. I had to print it 
out and then reboot into WinXP, open  Thunderbird, type it in by hand, 
and I'm a lousy typist.
