Open Firefox 1.0 and in the address bar type: about
:config
1. Find browser.tabs.showSingleWindowModePrefs and double click on it so it = true
2. Find network.http.pipelining and double click on it so it = true
3. Find network.http.pipelining.maxrequests double click on it and change it from 4 to 100
What do these changes do?
1. Then enables advanced tab options in your Tools/Options page ()
2. This enables option #3.
3. This makes FF use 8 threads to each page.. Bascially, if you thought FF was fast before, try it after this.
