A quicker firefox

Some great tricks to speed up your firefox browser here
Here a few in the list I tried and that real speeds up the browsing

1. Access the firefox config by typing about:config in the address bar
2. Change network.http.pipelining to true
3. Change network.http.proxy.pipelining to true
4. Change network.http.pipelining.maxrequests to 8
5. Create a new variable content.notify.interval (right-click in the window and select New -> Integer). Click OK and enter value as 500000
6. Create a new variable content.notify.ontimer (right-click in the window and select New -> Boolean). Click OK and enter value as true
7. Create a new variable content.switch.threshold (right-click in the window and select New -> Integer). Click OK and enter value as 250000
