Blazing Fast Firefox...
A dial up internet connection is a frequent cause of temporary insanity, leading to all sorts of damage, from raving lunatics throttling the unfortunate pedestrian to CRT monitors being hurled from 16th floor windows (and killing the unfortunate pedestrian?. Pipe-lining is your friend. It simply enables Firefox to load multiple things on a page at once, instead of one at a time.

1: Type “about:config” into the address bar and press "Enter". Type “network.http” in the filter field, and change the following settings (double-click on them to change them):
2: Set “network.http.pipelining” to “true”
3: Set “network.http.proxy.pipelining” to “true”
4: Set “network.http.pipelining.maxrequests” to a number like 20. This will allow it to make 20 requests at once. Don't set it too high though..
