This is only for people who use FireFox and want to browse the internet faster, I just tried it, and it works great.
And also, Firefox tend to take up a lot of cpu usage, we will change that too

First ;
Make a new tab, and write about:config in the browser menu.
You will see a lot of different lines etc, but you just need to right click wherever you want, and select "new - Integer"
Then you write browser.cache.memory.capacity, click ok. and then write 16384. (its 16mb).
Ok, so now firefox wont take up so much CPU usage.
Lets make it browse faster shall we?
Again, make a new tab and write about:config in the browser menu.
Search for network.http.pipelining, change it to true. (just click it twice)
Search for network.http.proxy.pipelining , and change it to true as well.
Search for network.http.pipelining.maxrequests , and change the value to 8, (higher numbers wont have any affect)
Then right click wherever you want, select "new - Integer"
name it nglayout.initialpaint.delay , and click ok. The value should be 0.
Now you're done.
Just restart FireFox and feel the difference

Ow if it doesn't change right away, you might have to restart the comp

I found this on a Swedish firefox FAQ btw.
