Starting with Firefox release 70, the browser is called Firefox Browser. Here’s how to use the latest privacy and security features, some of which come from Quantum.
Firefox Uses Multiple Processes
Before the Quantum update, Firefox ran everything in a single process. If a website or web page were loading poorly, the entire browser would perform sluggishly. If a tab crashed, the whole browser would crash.
To solve this problem, Firefox Quantum allowed users to control the number of processes the browser could run. By default, Quantum used four processes to view and render web content. Most modern computers come equipped with a multi-core CPU, so the default setting works well for the average user.
How to Disable Firefox Browser’s Default Performance Settings
With the latest Firefox Browser, users can’t specify a maximum number of processes. However, they can disable Firefox’s recommended performance settings and turn on hardware acceleration, so the browser uses your computer’s graphics processor instead of its CPU to display graphic-heavy content.
Here’s how it works:
Launch Firefox and select Firefox > Preferences. (On a Windows PC, select the menu icon (three lines), then select Settings. ) Scroll down to Performance. You’ll see Use recommended performance settings checked, which is the default setting. Uncheck Use recommended performance settings. You’ll see Use hardware acceleration when available automatically appear with a checkmark indicating this feature is activated. Firefox Browser will now use your graphics card to display media-based web content.
Firefox Now Uses Less Memory Than Chrome
The Quantum overhaul made Firefox quicker and lighter on system resources and added a more modern, minimalist-style interface. Using the Photon design language, Mozilla’s developers produced an intuitive browsing experience that displayed more web content. In addition to being twice as fast as Firefox 52, Quantum used 33% less memory than Google Chrome.
Quantum’s speed boost still endures. Mozilla says the Chrome web browser uses 1.77 times as much memory as the Firefox Browser.
How to Customize Tracking Protection in Firefox Browser
The release of Quantum introduced the option to enable Tracking Protection while browsing. Previously, this option was only available in Private Browsing mode.
Firefox Browser has even more robust Tracking Protection functionality. Here’s how it works:
Launch Firefox and select Firefox > Preferences. (On a Windows PC, select menu icon (three lines) > Settings. ) Select Privacy & Security from the left pane. Under Enhanced Tracking Protection, select Standard, Strict, or Custom. Standard offers balanced protection and normal page-load times. Strict has stronger protections, but some sites or content won’t work well. Custom allows you to choose which trackers and scripts to block. You also have the option of sending websites a Do Not Track signal. Choose Always or Only when Firefox is set to block known trackers (default).
How to Take Screenshots in Firefox Browser
Firefox Quantum introduced a built-in screen-capture option accessible from the Page actions drop-down. In version 88 and later, Firefox removed the ability to take screenshots from the address bar. However, it’s still easy to take screenshots in Firefox in three ways.
Use the keyboard shortcut Ctrl+Shift+S (Windows PC) or Command+Shift+S (Mac). Right-click anywhere on the screen, then select Take Screenshot.
Or, add a screenshot function to the toolbar:
Right-click on the toolbar and select Customize Toolbar. Drag the Screenshot icon into the toolbar. Access the screenshot function from your toolbar.
Automatically Restore Firefox Browsing Sessions
Firefox Quantum introduced the ability to restore your previous session when you launch the browser. The feature still works: Go to the History tab and select Restore Previous Version, and it will restore your last session tabs.
