FireFox - Speed it up.

The following FireFox Browser Tricks will probably only work if you have a high-speed / broadband internet connection. If you have a dial-up internet connection, then even if you try the following tricks, chances are you wouldn't notice any difference after applying these tricks.

By default, FireFox browser is already a fairly fast browser, but here we will offer some "tricks" that you can do to help speed it up a notch.
Type in: "about:config" (without the quotes) in the Address bar and press Enter. You may get a warning message, so if you wish to continue, click on the "I'll be careful, I promise" button on the warning page.

On the "about:config" screen, scroll down to the "network.http.pipelining" options.
Firefox normally processes all HTTP requests sequentially. Once it sends one out, it waits for a response before sending the next request to a server.

Set the "network.http.pipelining" and "network.http.proxy.pipelining" to a value of "true".

Now set the "network.http.pipelining.maxrequests" option to 30 and Firefox will now send up to 30 HTTP requests at once, theoretically, although not always, making your browser that little bit faster.

Before you close the window, right-click anywhere on the "about:config" page and select "New->Integer". Then type in "nglayout.initialpaint.delay" (without the quotes) and enter 0 as its numerical value. Firefox will now render pages immediately instead of waiting its default 250 ms, a slight but noticeable difference when you're surfing the Web.
