How To Speed Up Firefox Quantum in Windows 10

The focus of Mozilla with Quantum is that it’s up to 4 times faster than Google Chrome but little by little when using Firefox Quantum we may notice some slowness, and this can significantly affect the optimal performance of Quantum.

Through this tutorial, you will learn some methods to speed up to the maximum Quantum and thus enjoy its powerful functionalities.

Method #1: Auto Discard Firefox Quantum Tabs

Auto Tab Discard gives us the opportunity to configure specific rules to discard the Quantum browser tabs that are open automatically.

This plugin doesn’t close the tabs; it’s only responsible for suspending them so that they don’t use memory inadequately.

This Plugin is available at the following link:


Method #2: Configure Firefox Quantum Tracking Protection

Firefox Quantum has protection against tracing which makes use of a list provided by Disconnect to identify and block web crawlers and thus improve navigation and privacy.

Although it’s a good security practice, in some cases it has been mentioned otherwise, that the protection against tracking causes a negative impact on the computer.

To configure this, go to the Quantum menu and there click on Preferences:

firefox quantum preferences

In the new window go to the Privacy & Security section and in the section Tracking Protection, click Never.


Method #3: Configure Hardware Acceleration in Firefox

Although its name indicates an improvement in browser speed, hardware acceleration is responsible for using most of the resources, such as disk, memory, and graphics, to offer a better experience to the end user.

In a computer with high-end hardware this can be a vast improvement, but otherwise, can have a negative impact.

To disable hardware acceleration, go to Preferences > General and in the Performance section, disable the checkbox: “Use hardware acceleration when available.”
