Right-click (for Apple users ctrl+click) anywhere in the about:config window, select New–>Boolean from the pop-up menu.

Step 7:

Mozilla applications regularly render what has been received at any instance, instead of waiting for a page to completely download to display it to the user. This option controls the maximum amount of time the application will be unresponsive while rendering pages.

Right-click (for Apple users ctrl+click) anywhere in the about:config window, select New–>Integer from the pop-up menu.

Step 10:

Notify Backoffcount
This option controls the maximum number of times the content will do timer-based reflows. The page reflows only once when it has finished downloading after reaching this number.

Right-click (for Apple users ctrl+click) anywhere in the about:config window and select New–>Integer from the pop-up menu.

Step 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 switches back to low-frequency mode when you have not been active for a certain amount of time. This preference controls that amount of time.

Right-click (for Apple users ctrl+click) anywhere in the about:config window and select New–>Integer from the pop-up menu.

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

Step 12:

NGLAYOUT INITIALPAINT DELAY

Mozilla applications render web pages incrementally, they display what has been received of a page before the entire page has been downloaded. Since the start of a web page normally does not have much useful information to display, Mozilla applications wait a short interval before first rendering a page. This preference controls that interval.

Right-click (for Apple users ctrl+click) anywhere in the about:config window and select New–>Integer from the pop-up menu.
steps in speeding firefox

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

Enter 0 and click OK when prompted to enter a value.

  1. Like what you said, I agree that pipelining is one of the most effective ways to speed up firefox. Aside from this method, we can speed up firefox by getting the latest patches available. Setting time for automatic updates when you’re sleeping or while you’re computer is idle is another great idea to reduce the amount of interference to your web browsing tasks.
