Firefox tricks

Firefox tricks:-

1. faster loading

network.http.pipelining = true
network.http.proxy.pipeling = true
network.http.pipelining.maxrequest= 50 
nglayout.initialpaint.delay = 0

2. for USB or portable media 

browser.cache.disk.enable = false
browser.cache.memory.capacity = as much ram as you can ...

3. tunnel dns
To prevent Firefox from doing NS lookups enter {{about:config}} in the URL text field
and double click on the {{network.proxy.socks_remote_dns}} to set it to true.
