Info: HTTP is the application-layer protocol that most web pages are transferred with. In HTTP 1.1, multiple requests can be sent before any responses are received. This is known as pipelining. Pipelining reduces page loading times, but not all servers support it!

03. Go back to the Filter search bar and type network.http.pipelining.maxrequests Double-click this option and set its value to 8.

Info: In IPv6-capable DNS servers, an IPv4 address may be returned when an IPv6 address is requested. It is possible for Mozilla to recover from this misinformation, but a significant delay is introduced.

11. CONTENT SWITCH THRESHOLD

You can interact with a loading page when content.interrupt.parsing is set to true. When a page is loading, the application has two modes: a high frequency interrupt mode and a low frequency interrupt mode. The first one interrupts the parser more frequently to allow for greater UI responsiveness during page load.

The low frequency interrupt mode interrupts the parser less frequently to allow for quicker page load. The application enters high frequency interrupt mode when you move the mouse or type on the keyboard and switch back to low frequency mode when you had no activity for a certain amount of time. This preference controls that amount of time. Right-click (Apple users ctrl+click) anywhere in the about:config window and select New and then Integer from the pop-up menu.

A. Enter content.switch.threshold in the New integer value pop-up window and click OK.

12. NGLAYOUT INITIALPAINT DELAY

Mozilla applications render web pages incrementally, they display what??™s been received of a page before the entire page has been downloaded. Since the start of a web page normally doesn’t have much useful information to display, Mozilla applications will wait a short interval before first rendering a page. This preference controls that interval. Right-click (Apple users ctrl+click) anywhere in the about:config window and select New and then Integer from the pop-up menu.

steps in speeding firefox

A. Enter nglayout.initialpaint.delay in the New integer value pop-up window and click OK.

steps in speeding up firefox

B. You will be prompted to enter a value. Enter 0 and click OK.

That’s it! Now restart Firefox and your browsing as well as downloading speed will be much more faster. Good luck.peace
