What can I do to make Firefox run faster?

Keep reading if you’re looking for ways to improve your Mozilla Firefox surfing experience. We’ll go over the best methods for getting Firefox to run like new again.

Method 1. Update Firefox to the latest version

It’s simple to update Firefox to the current version. Make sure you have some time for this because it should only take a few minutes.

  1. Hover over Help in the context menu after clicking the menu button. Select About Firefox from the drop-down menu.
  2. Firefox will search for updates and, if any are discovered, will immediately download them. To update to **.**.*, click the Update to **.**.* button.
  3. Click the Restart to update Firefox option after the process is finished. Your browser will download and install the updates, giving you access to every new feature and bugfix.

Method 2. Enable hardware acceleration

Firefox is a strong browser that can be accelerated with hardware to make it run quicker. If you wish your computer’s resources to be utilized more efficiently, enable this setting!

  1. To get started, open Firefox and type “about:preferences” in the address bar. To get to the preferences page, press the Enter key on your keyboard.
  2. Keep your cursor on the General tab and scroll down to the Performance section. Make sure the “Use suggested performance settings” option is turned off.
  3. There should be a new option available. To enable hardware acceleration, enable “Use hardware acceleration when available.”
  4. If necessary, increase or decrease the content process limit. If your machine has more than 8GB of RAM, you can keep it at the default setting of 8. Otherwise, if Firefox is significantly slowing down your computer, lower the limit.
  5. Check to see whether your browser is now faster.

Method 3. Manage your tabs

Close any tabs that aren’t in use to ensure that your resources aren’t wasted. You can use an extension that suspends inactive ones automatically, or you can manually close them! We advocate utilizing an add-on like Richard Neomy’s Auto Tab Discard.

Method 4. Clear your cache, cookies, and history

Clear your browser’s cache to make it run faster and avoid any issues caused by the information saved inside. If anything doesn’t look or work right, clean away all of those pesky cookies to prevent it from happening again.

  1. Click the three lines in the top-right corner to bring up the Firefox menu, and then select Settings from the list of options.
  2. Go to the Privacy and Security section. Scroll to the bottom of the page until you find the Cookies and Site Data heading.
  3. To access the interface, click the Clear data button. After you’ve selected both options, wait for Firefox to finish deleting your data.
  4. Scroll down to the History section once the initial process is completed. To clear your history, go to this page and click the Clear History button.
  5. Choose the objects you want to get rid of. Make sure you go over everything thoroughly so you don’t lose important information like your saved passwords. Click Clear Now once you’ve picked everything you wish to get rid of.
  6. Make a habit of repeating this procedure anytime Firefox becomes sluggish.

Method 5. Disable Add-ons

Third-party add-ons, in particular, can significantly slow down your browser. Remove or disable any add-ons you don’t use very often to reduce the chances of this happening.

  1. Click the menu button in Mozilla Firefox, then select Add-ons and Themes from the context menu.
  2. Toggle over to the Extensions tab. Look for any extensions you don’t use any longer, as well as any strange entries. For example, extensions that you are unfamiliar with or that appear shady and come from an unknown company.
  3. Click the More actions button and select Remove from the context menu to uninstall any extensions you don’t want to keep on your device.

Method 6. Turn off Accessibility Services

When utilizing Accessibility Services, several Firefox users have complained that the browser is slow. Turning them off will prevent this and provide you a speedier experience!

  1. Click the three lines in the top-right corner to bring up the Firefox menu, and then select Settings from the list of options.
  2. To access the Permissions section, go to the Privacy and Security page and scroll down.
  3. If it’s checked, uncheck “Prevent accessibility services from accessing your browser.” Restart Firefox to test if the modifications have taken effect and if the browser is now faster.

Method 7. Minimize memory usage

Firefox includes an option to keep memory use to a bare minimum. This may aid in the speeding up of the browser.

  1. To get started, open Firefox and type “about:memory” into the address bar. To go to the memory management page, press the Enter key on your keyboard.
  2. Click the Minimize memory consumption button under the Free memory column. Following that, the browser will free up whatever RAM it isn’t using, which may assist.

Method 8. Disable Firefox Data Collection

Firefox is continually coming up with new methods to improve your surfing experience, such as anonymously reporting your browsing habits. However, this may cause your browser experience to slow down, therefore disable those data collecting settings if necessary!

  1. Go to Privacy and Security > Settings.
  2. The Firefox Data Collection and Use header can be found by scrolling down the page. Make sure this section’s choices are all unchecked.
  3. Check whether your experience has improved by restarting your browser.

Method 9. Tweaks in the advanced configuration

Many options are available in Firefox’s accessible configs menu, which may be altered with only one click! Adjust these parameters to make the browser run faster.

  1. In the URL bar of Firefox, type “about:config.” To get to the advanced configuration page, press Enter. To continue, click the I’ll be careful, I promise button.
  2. Make the following modifications:
  1. Set browser.download.animateNotifications to false
  2. Set security.dialog_enable_delay to 0
  3. Set network.prefetch-next to false
  4. Set browser.newtabpage.activity-stream.feeds.telemetry to false

  16. Set toolkit.telemetry.updatePing.enabled to false
  1. Restart Firefox and check how it compares to before making these adjustments. After making these changes, you should notice Firefox running much smoother.

Method 10. Refresh Firefox

If nothing else seems to be working, you can try resetting Firefox to its basic settings without having to reinstall it. This will guarantee that your browser is set to factory defaults and that no customizations are slowing it down!

  1. To get started, open Firefox and type “about:support” in the address bar. To go to the support page, press the Enter key on your keyboard.
  2. Look for the section called “Tune up Firefox.” Click the Refresh Firefox button under this.
  3. To confirm the procedure, click Refresh Firefox again in the pop-up box, and then wait for the browser to return to its default state. Check to see if it’s still operating slowly after that.
