Firefox slowness on Ubuntu 10.04 and 10.10

I've been experiencing a very annoying slow browsing experience on my Firefox but I've found a fix for it. Type about:config in the address bar and hit enter.

from there you should see a list of configuration lines. Look for the following:

- network.dns.disableIPV6 

- network.http.pipelining

- network.http.proxy.pipelining

on all of these click with the right button and toggle them from false to true. Lastly look for

-network.http.proxy.pipelining.maxrequests

change this one from whatever is there (2 in my case) to 8

I hope this helps.
