Firefox is a popular web browser that is known for its speed and flexibility. However, some users may find that Firefox is not as responsive as they would like it to be. This can be due to a number of factors, including the settings that are used in Firefox. In this article, we will discuss how to tweak Firefox’s responsiveness config setting in order to improve performance. First, open Firefox and click on the “Firefox” menu button (or press “F3”) and then select “Preferences.” In the Preferences window, click on the “Advanced” tab and then under the “Performance” heading, click on the “Responsiveness” button. The Responsiveness window will open. In this window, you can adjust several settings related to how Firefox responds to user input. The first setting that you will want to adjust is called “Speed.” This setting determines how quickly Firefox responds when users interact with it. You can adjust this setting by clicking on the arrow next to it and selecting one of three options: Fast, Normal or Slow. The next setting that you will want to adjust is called “Tapping Delay.” This setting determines how long it takes for Firefox to respond when a user taps on a link or an element within the browser window. You can adjust this setting by clicking on the arrow next to it and selecting one of three options: Fast, Normal or Slow. The last setting that you will want to adjust is called “Scroll Speed.” This setting determines how quickly Firefox scrolls through web pages when users drag their mouse across them or use keyboard shortcuts such as arrow keys or Page Up/Page Down. You can adjust this setting by clicking on the arrow next to it and selecting one of three options: Fast, Normal or Slow. ..


When Firefox is loading a page it uses one of two modes: There’s a high priority mode that doesn’t pay as much attention to your mouse and keyboard, but loads the page faster. There’s also a lower priority mode that interrupts the parser more often to respond to input events. It’s even documented at Mozillazine.

What we can do is tweak the amount of time before Firefox switches from lower priority mode back into high priority mode.

Type about:config into the Firefox address bar, and then filter by the following:

Most likely the key doesn’t exist yet, so you’ll have to set it by right-clicking in the empty area and selecting New \ Integer. Use these values when prompted:

Key Name: content. switch. threshold Key Value: 1000000

The default value is 750000, or 3/4 of a second. The more time that you tell Firefox to wait before resuming high priority mode, the more responsive the application will feel… but it will obviously take a little longer to load the pages. You could reverse this if you were more worried about speeding up page load time.

Note that this setting only works if you haven’t changed content.interrupt.parsing to false.
