How to Speed Up Mozilla Firefox?


With the development of Firefox Quantum. Mozilla became one of the fastest browsers out there. Now it’s known for consuming 25% less RAM than Chrome does which not only improves the browser’s speed but also increases the overall system’s efficiency.

Still, there is no limit for perfection. Even at its super-fast speed, Mozilla’s speed can all be significantly increased. So, if you want to boost your browser to the highest possible levels of performance, we assembled a list of tire-and-proven methods.

The best thing is, neither of these requires you to have any technical expertise whatsoever. All you need to do is follow several simple steps – and we lay them all out in this guide.

1. Use A Smaller Portable Version

Some laptops cannot take huge functionality of a full Firefox version. Al security add-ons, design improvements, and countless extensions – old devices just can’t take all this workload.

The fix: to increase the speed of your browser, opt for simplicity instead and use a light portable software.

How to do it?

The fix: turning the Toggle Tracking Protection Off.

How to do it?

  1. Go to Firefox’s Options menu and pick the ‘Privacy and Security’ panel. 
  2. Find Tracking Protection in am menu and disable it

2. Turn of Multi-Process Windows.

While the majority of users considered Firefox Quantum a huge improvement, this certain;y wasn’t the case for everyone. In fact, some felt that Firefox Quantum update slowed the browser down. The curious thing is, they weren’t wrong either.

The issue is that Firefox Quantum turned Firefox in a multiprocess browser, just like Google Chrome. Older Firefox’s versions launched a program in a single operating system, running united Java Script processed for processing UI and web content.


The latest versions, on the other hand, adapted Chrome’s approach to data processing and run UI and web content in different processes. However, old Windows versions or hardware can be incapable of taking this workload.

The fix: Go to ‘about config’ settings in your Firefox, find a command ‘browser.tabs.remote,autosart., press the button edit the settings to ‘False’.

3. Edit Content Process Limit

The multiprocess approach also impacted the amount of processed content. Now that UI and web content are separated into different categories, the browser has to handle four times and many procedures and some computers just can’t take such numbers.

The fix: decrease the number of processes if you use an old device; increase them if you use a powerful PC.


How to do it?

  1. Open Firefox settings panel.
  2. Find a ‘Performance’ panel on the lower part of the page.
  3. Take down the tick from ‘Use recommended performance settings’. 
  4. Open dropdown menu near ‘Countdown processes’ and increase or decrease them depending on your PC capacities. The lowest number is 1; the highest one is 7. 

You can experiment with different numbers figuring out the option that suits your device best. Just a word of a warning: if you push the number too high, you may experience some crashes. No worries, though – you can always come back to settings and decrease the number again. 

4. Improve Your Scrolling Speed

Your online speed depends on the huge part on your scrolling’s responsiveness. If you read books online or browse through long documents, you need your scroll to keep up with your reading speed. Sure, it hugely depends on your system’s speed and the age of a device  – you can only push so much. Still, some efficient tweaks can significantly improve the situation. 

The fix using Quantum-compatible extensions for increased scrolling speed – like YASS (Yet Another Smooth Scrolling). The add-on allows you to modify scrolling speed, sensitivity, acceleration ad, even scrolling automation. You can determine the speed of automatic scrolling or increase the seed closer to the page’s bottom. 

5. Make A Good Use Of Tab Discard

Using multiple tabs simultaneously is the fastest way to slow down your browser. Still, sometimes you can’t just close the page, especially if you are researching or doing online shopping. What to do when merely removing a tab is not an option?

The fix: install an add-on hat puts your tabs on a waiting mode if they remain inactive for a specified period. The tabs are not closed, just suspended from using the huge amount of your RAM. You can choose some tabs to be always active – these are typically the ones you use the most.


How to do it?

  • Open Firefox and go straight to the Settings.
  • Find the ‘Add-ons’ button and select ‘Extensions’. 
  • Search for extensions that support tab discard. 
  • Install the extension that you liked the most. 

6. Turn Accessibility Services Off

Some users noticed that using Firefox Quantum led to Mozilla crashes and memory leaks. However, in most cases, it’s not the problem of the update per se. Some users happen to face a bug of Firefox Accessibility Services – although it’s not a common occurrence.

Accessibility services provide users with page voice readers, braille interface. If a bug occurs, they keep consuming you RAM even though you never requested accessibility assistance.

The fix: open Settings and disable these additional services if you don’t rely on them. 

How to do it?

  1. Open Settings and select the ‘Options’ menu. 
  2. Open ‘Privacy and Security’.
  3. Find the panel with the command ‘Prevent accessibility features from accessing your browsers’ and put a tick a box nearby. 

7. Set a Low-Resolution Mode if you use Mac

Windows users can skip this one. 

Retina screen of you Mac that you are usually so proud of tends to play bad games with Mozilla’s speed. The browser starts taking its sweet while to process graphics and pages load much slower than they usually should. 

The fix: put Firefox Quantum into a low-resolution mode. 

How to do it?

  • Go to your Mac’s settings, select the Firefox app, and click Get info. 
  • The ‘Info’ panel presents you with resolution settings. Select the command to ‘Open in Low Resolution’. 
  • Now Firefox will produce the graphics of lower quality and take less time to process all graphics images.

8. Disable Toggle Tracking Protection

Toggle Tracking Protection prevents browsers from loading a third-party content – pop-ups, push-ups, ad tabs, also protecting you from malvertising and spam ware. Even though theoretically it’s supposed to increase your browsing skill, it takes a lot of time for a browser to analyze reach page. On a fast device, you’ll never notice the difference, but on the older device or Windows version, these adverse effects will be.


9. Make Sure You Have Enough Space

The longer you use the browser, the more data it gathers and stores.

The fix: To keep the speed aways at the stead level, be sure to clean the memory in time. 

How to do it?

  • Type a memory command in the address bar. 
  • The browser loaded the memory page with Settings. Here you choose ‘Minimize memory usage’ in the ‘Free memory’ panel. 


  • If your Firefox Quantum is glitching, it means, you have to adapt the browser to your device’s technical capacities. 
  • By disabling excessive accessibility and security functionality, you can free memory up for essential functions that you use.
  • Avoid opening many tabs but if it’s necessary, use a dedicated extension for efficient tab management. 
  • Control memory usage. On a memory tab, you can check how Freifox disposes of your system’s resources and edit settings.
  • Prioritize speed over quality of graphics and add-ons. The more complicated is the browser’s functionality, the slower will the overall speed be.
