Disabling Unnecessary Features
Disabling unnecessary features can significantly speed up Mozilla Firefox. One of the most effective ways to do this is to disable animations. Firefox displays small animations when opening or closing tabs, but you can avoid some hang-ups by disabling them.
To disable animations, open a new tab and enter “about:config” in the address bar. Then, set browser.tab.animate to False and browser.panorama.animate_zoom to False. This simple tweak can make a big difference in your browsing experience.
Another feature that can slow down your browser is prefetching. Prefetching loads pages before you visit them, guessing which links you’ll click on. If you have unusually slow load speeds, a buggy prefetch could be the issue. You can disable prefetching by making the following changes in the about:config page: change network.dns.disablePrefetch to True, change network.prefetch-next to False, and change the value of network.http.speculative-parallel-limit to 0.
Add-ons can also slow down your browser greatly, especially third-party ones. Make sure to remove or disable any add-ons you don’t use often to minimize the risk of this happening. To uninstall any extensions you don’t want to keep on your device, click the More actions button and select Remove from the context menu.

Disable Add-ons

Disabling add-ons can significantly speed up your browser. To do this, enter "about:addons" in the address bar or click the menu icon and select Add-ons.
Disable one add-on at a time and browse for a while to see if it speeds you up. Visit the same page to remove the add-on permanently or re-enable it, depending on your test.
To remove or disable add-ons, start by clicking on the menu button and then select Add-ons and Themes from the context menu.
Switch to the Extensions tab and check if you notice any extensions you don’t use anymore or suspicious entries. For example, extensions you don’t recognize, or ones that look sketchy and come from an unknown company.

Consider Disabling Prefetching
Prefetching can be a sneaky feature that slows down your browser, but it's actually designed to help. It loads pages before you visit them, guessing which links you'll click on. If it's working correctly, it should only use idle browser time and increase load speed.
However, if you're experiencing unusually slow load speeds, a buggy prefetch could be the culprit. You can try disabling it to see if it makes a difference.
To disable prefetching, you'll need to make a few changes in the browser's settings. Open a new tab and enter "about:config" in the address bar. This is where you'll find the settings that control browser behavior.
Changing network.dns.disablePrefetch to True will disable the first form of prefetch. Next, change network.prefetch-next to False to disable the second form. Finally, change the value of network.http.speculative-parallel-limit to 0 to disable all prefetching.
Here's a step-by-step guide to disabling prefetching:
- Change network.dns.disablePrefetch to True.
- Change network.prefetch-next to False.
- Change the value of network.http.speculative-parallel-limit to 0.
If you're not sure if prefetching is the issue, you can try reversing these changes to see if your load speeds improve.
Disable Data Collection

To disable data collection, you'll need to restart your browser after making the changes. This will ensure that the new settings take effect. After restarting, you can check if your experience is better.
Here are the steps to disable data collection in Firefox:
- Navigate to Settings > Privacy and Security.
- Scroll down on the page until you see the Firefox Data Collection and Use header. Make sure that all options in this section are unchecked.
- Restart your browser and check if your experience is better.
